I would say, and I bet @Jean-Francois Lessard agrees, that is not a matter of "messing with my code" thing, but rather a matter of principles. A kernel module is supposed to do a kernel module or, In simple words, it interfaces the kernel with the hardware. The kernel means are to give the userspace a way to access the hardware. The module should not run any user business (eg: display something user-specific at boot/shutdown/whatever), but should in turn provide a service for the userspace to control the hardware. That's a simple principle in software engineering that's called "separation of responsibility", and is generally considered a good habit to agree with that principle. By the way, if your board has one or more colored leds, they are generally set up in the device tree and access basic GPIO system, so they are turned on as soon as the kernel starts.

I have currently this on SD-card: root@rock3a:~# ls -1 /boot/vmlinuz-* /boot/vmlinuz-5.10.160-39-rk356x /boot/vmlinuz-6.12.12-current-rockchip64 /boot/vmlinuz-6.13.1-edge-rockchip64 /boot/vmlinuz-6.1.99-vendor-rk35xx Only with the 5.10 kernel from Radxa, I get both NVMe and SATA when I use the overlay 'rock-3a-sata.dtbo'. With 6.12 and 6.13, there is only SATA, no NVMe. 6.1 lets the kernel/board crash, I have not further looked into that. So I can reliably use the SATA HDD, also hd-idle spindown works, I monitor the powerconsumption per day on 12V level and it is great. So as a slow clone/backup NAS it works and is acceptable. But ultimate plan is to make it a fast/main NAS, using the NVMe as cache and also for OS, so only SPI+NVMe+SATA. 5.10 kernel lacks various Btrfs features, so that is a no-go. I need at least 6.1, although I know weird virtualization tricks to get it to work on a functional level, but then also, I might hit issues with KVM on the Radxa rk356x kernel. I got the kernel from: https://radxa-repo.github.io/bookworm/files.list Regarding power, I now use 12V as base (common GND), feed 12V into the Rock3A USB-C connector and 3.5inch 12V pin on HDD and tap 5V from Rock3A GPIO and that feeds the 5V pin of the HDD. As said, that works very nice and stable. So it still looks like the 'rock-3a-sata.dtbo' overlay 'hides/disables all PCIe', where it should not do anything with the PCIe3x2 where the NVMe is on. I saw this: https://patchwork.kernel.org/project/linux-rockchip/patch/20250106100001.1344418-2-amadeus@jmu.edu.cn/ but not sure if it is related.

Hmm the plot thickens dmesg | grep Open - gives me this - so it's not finding the vfd.conf file and is looking in the Device Tree for instructions as a fallback - so where does this vfd.conf file go?

@Jean-Francois Lessard You won't believe it, but I found my error(s) .... For the solution I had to look at the dts Paolo (https://github.com/paolosabatino/leds-fd6551) suggested in his code. I missed a line that effectively makes SDA really open-drain. However, pinctrl is not relevant in this context. The fist line is bloody important, the second not so: i2c-gpio,sda-output-only; i2c-gpio,scl-output-only; Although they do incur warnings in the kernel log, they are indispensable because without them, i2c signals don't reach the fd6551 controller. Now everything works as expected. It shows (in fact, it showed ...) 88:88 right at the start and after that the actual time. Great! I'm going to write a pull request for Nicolas' Github repo so that he can integrate it with the Armbian distribution. I also edited your tm16xx source code to show 'boot' instead of 88:88, which is not my cup of tea. You also have to make sure you compile the driver als built-in and not as a kernel object. So you get the 'boot' writing roughly around second 2.8 in the boot process when plugging in the mains adapter and this is early enough for me. I attach all of the sources to this post. I hope you don't mind too much that I messed with your code and I apologize upfront. Best wishes, Deetsh tm16xx_boot.c display-client-snippet.dts

NB - evtest does not come with Armbian Bookworm.

TY for your reply. They definitely can be controlled by echoing values to the `/sys/class/leds/` and even though the "trigger" is set to "netdev" and tx and rx files appear, I'm not seeing any activity on those LEDs with network activity. I can manually make the LEDs blink by doing something like echo heartbeat > /sys/class/leds/lan-led/trigger cat /sys/class/leds/lan-led/trigger will show the available triggers, and a [] around the currently selected one. cat trigger none usb-gadget usb-host rc-feedback bluetooth-power rfkill-any rfkill-none kbd-scrolllock kbd-numlock kbd-capslock kbd-kanalock kbd-shiftlock kbd-altgrlock kbd-ctrllock kbd-altlock kbd-shiftllock kbd-shiftrlock kbd-ctrlllock kbd-ctrlrlock mmc0 timer oneshot disk-activity disk-read disk-write ide-disk mtd nand-disk heartbeat backlight gpio cpu cpu0 cpu1 cpu2 cpu3 activity default-on transient flash torch panic [netdev] mmc1 It looks very configurable, just doesn't seem to be "automatically" working to show network activity.

@Meestor_X From what I can see in the schematic for the E20C, the Ethernet LEDs are wired directly to the Ethernet controller chip. Can not be accessed by the SoC/OS via GPIO, therefore there is nothing you can do to control their behavior. However I would think that it should just work out of the box, so there is nothing you need to do either. If it doesn't work then I dunno, ask Radxa or something

@Jean-Francois Lessard Thanks for your comprehensive answers. They helped me a lot, but as ill luck would have it, new questions arose ... As far as I can tell, the driver is loaded at second 2.7, which is perfectly early enough for me. Once the driver is ready to operate 8888 should be visible. Well, should .. I managed to get it running once and then I changed the config or the board dts or whatever and I never reached this state again, what a sh*t! May be you can spot any error in the dts, but I have the feeling that the error lurks somewhere else. You are so right, one can comment accurately on my questions if there is no dts you can look at. This time I attach my full dts to this post, promised. BTW, like I said before, I have an H96 Max V56, which has an FD6551 on the board. So there is no confusion. Rest assured, brightness is behaving as expected but is waaay to dark for me. If only those leds had white color ... Well I have made the led display "brighter" in a rather unconventional way -> I used a saw and sawed out a little rectangle from the front. Maybe my tv box doesn't look as pleasing as before, but the led display is much brighter now. Form follows function , ya know?! 🤣 Since the led display did work once, I think both SDA and SCL are configured correctly. i2c-6 is, in fact, the i2c node the kernel assigned to the tm16xx driver. When my tv box starts, somewhere in the kernel log I get i2c-gpio display-client: using lines 12 (SDA) and 11 (SCL) ... tm16xx 6-0024: Failed to set brightness: -6 tm16xx 6-0024: Failed to initialize display: -6 (-6 is ENXIO -> no device) The driver simply is unable to talk to the chip and I really don't know why. BTW my kernel has version 6.12.12 and the tm16xx is not built in but is a .ko Understood, I tried them and they worked, but thanks for the explanation (I found them earlier on your Github pages.) Yep, later. Led display isn't working right now ... 🙂 I have the feeling that using pinctrl would necessitate a "slight" rewrite of your driver and at the moment my inclination to go down this rabbit hole is, well, limited... But the question is,if there is a pinctrl definition regarding these two GPIO lines, will this definition interfere with the definition of the gpio lines in the display-client section? When using pinctrl I couldn't find any way to set the baud rate used for the communication. Is it unnecessary or is there some sort of auto-negotiation? So if you have any idea how I can arrive at a working led display again, please(!) let me know. Currently I'm at my wits end. All the best, Deetsh P.S.: oh, there is one thing I need to ask you: Do you know a way to make testing new versions of the dts easier than building an image and downloading in the emmc? myboard.dts

Hi, I got my recording from Headphone Mic fixed. Here is what I make work for me: a) have pinctrl-0..2 set in the i2s0 b) make sure the reg=0x11 for the i2c1-codec c) add the Mic Bias.

Works for me...

I managed to get the SPI to work. It is tested with the Minimal/IOT images with Armbian Linux v6.6 from the build date of end of January. I tried to copy the .dtbo files ( from above) to the following location: -/boot/dtb-6.6.72-current-sunxi64/allwinner/overlay The details can be found in the guide made by adif. 1. ls /dev > there is no spi 2. go to armbian-config What is spi* in orange pi zero3 ls /dev gpio readall 4. copy the .dtbo files ( from forum) to the following location -/boot/dtb-6.6.72-current-sunxi64/allwinner/overlay reboot gpio readall

Thank you @going I made the changes to the build as you suggested. No change. I modified the ftdfile to remove the serial@1c28c00. This changed the behavior, worsening it. I attempted to make an overlay to remove the serial port. That failed. I modified the ftdfile to remove the Bluetooth portion of the dtb. The results follow. I did read the examples on how to make an overlay. I need to spend more time figuring out overlays. Unless you have another suggestion, I'm going to get different hardware. I'm looking for a low cost, Arabian supported board with Ethernet and UART that can support PPS and supply 3.3v to my GPS board. I am avoiding wireless and USB solutions.

@dfahren thanks for your feedback. I'll try to answer your questions but they are rather broad and not strictly related to the driver itself. Plus, it's difficult to have a clear understanding without knowing your DTS configuration. 1. The display device is usable as soon as the tm16xx device driver is loaded by the kernel during boot (which will turn on all display LEDs at this stage, showing 88:88). There is no way to load the driver before that. Some other LEDs might be hardware controlled or configured by u-boot preloader, before the kernel is loaded, so you can't compare against these. Currently display.service loads the driver using ExecStartPre at basic.target, which is somewhat the earliest it can using systemd. There might be other ways to load the driver a couple of milliseconds before but I don't think it worths investigating. Anyway, the display-service won't show the correct local time before network and ntp will have loaded properly (local time is only available from user space, not within kernel space). 2. Display brightness is set by using controller specific values, there is no amps to control. You can try setting different `/sys/class/leds/display/brightness` values to see if there's a bug (0 is off and `cat /sys/class/leds/display/max_brightness` being the max value for your configured controller). If brightness is not behaving as expected, it is likely that you have not configured the right controller in your `compatible` string of the display-controller node in your DTS. You can check the controller model by looking at the controller chip on your device main board. 3. The display would not work with incorrect I2C SDA and SDL pins configuration. I guess that your i2c-6 is another unrelated device in your DTS. You can check which i2c device is used by your display controller using `ls -l /sys/class/leds/display/device` 4. "link" sysfs is not to control a led status but rather to configure some specific led trigger. You need to check specific led trigger module documentation to understand how to use these sysfs attributes. If you want to turn on or off a led without using a led trigger, you can do so: ``` # turn on a specific led/symbol echo 1 > /sys/class/leds/display\:\:lan/brightness # turn off a specific led/symbol echo 0 > /sys/class/leds/display\:\:lan/brightness ``` Please refer to https://github.com/jefflessard/tm16xx-display/blob/main/README.md for tm16xx specific documentation. 5. Use `display-utils -a` as documented in tm16xx documentation at https://github.com/jefflessard/tm16xx-display/blob/main/README.md then you can update your DTS. 6. If using software i2c (i2c-gpio) you should not require pinctrl. If using hardware i2c, it depends on the specific hardware configuration of your device.

I am attempting to boot my BPI-M2U. It will start the boot, but it does not get to the login prompt. Instead, it resets and starts the boot process over. I am using a 3A Power Supply rated for Pi's. I've tested with other power supplies. One of the BPI images does boot and run. The SD card is untested but works for the other OS. In case it was the SD card, I flashed the Armbian image to the eMMC and attempted to boot off that. I am using the Armbian_23.05.0-trunk_Bananapim2ultra_bookworm_current_6.1.24 image. While the exact spot it dies might change by a few lines, the following is about where it gets. I can build Armbian images from the git repo so any suggestions are welcome.

@cOrnelius YES I know how to maintain the current system manualy, but with the next release I' l have to do it again. @Igor, your PR modification looks like the right solution adding the missing group T H A N K S! P L E A S E can you also point me where I will find the right spot where I can define the right owner for the some specified directories like the: /sys/class/gpio ? Is there a list for mapping the right owner to a directory? that can be modified? Regards Wolfgang

sudo groupadd gpio sudo adduser wollik gpio

Hi Members, I'm setting and reading the GPIO PINs for different BPI's frequently only by bash by maintaining the /sys/class/gpio/xxx values. The only problem is that all these files belong to root :root and I have to use the sudo command in my scripts. I've read about putting a non root user to the gpio group will fix that. But on Armbian there is no "gpio" group ;( That seems the reason why the directory /sys/class/gpio is not prepared as root:gpio Please has someone an idea when this will be implemented? Regards wollik

@Christopher Ruehl congratulations, great finding! That could explain some of the compatibility issues people is still having. I have a couple of questions: 1) what is the purpose of enabling the internal gpio pull-up when there already is the external pull-up? 2) do you have any suggestions to apply to existing device tree to enhance compatibility for other users? Exchanging SMD components on the board is out of the league for most people Thanks!

Hi Pet, The axp209 modules should already be loaded by default, if not then they should at least be included in the kernel. This is the pmic onboard the cubietruck. Are you using a lipo or coin cell for rtc? You can check the current state by look at '/sys/bus/i2c/devices/i2c-x/x-0034/battery. Replace x with the i2c bus that the axp209 is assigned to. Normally this should be 0 but not always the case. For example this it what it looks like on my device: [ 2.973703] axp20x-i2c 1-0034: AXP20x variant AXP209 found [ 2.981221] input: axp20x-pek as /devices/platform/soc/1c2ac00.i2c/i2c-1/1-0034/axp20x-pek/input/input0 [ 3.000378] axp20x-i2c 1-0034: Backup (RTC) battery charging is disabled [ 3.000562] axp20x-i2c 1-0034: AXP20X driver loaded [ 5.367992] axp20x-gpio axp20x-gpio: DMA mask not set [ 5.382424] axp20x-gpio axp20x-gpio: AXP209 pinctrl and GPIO driver loaded [ 21.124944] axp20x-adc axp20x-adc: DMA mask not set best of luck Ryzer

>I think you only need spidev turned on in armbian-config This is what I did first, but could not find any ( in the /dev ) spi device. This triggered my to start searching for a solution and as far as I understand from this thread, there is a misconfiguration in the standard image. This is from the armbian website of the orange pi zero 3: Do you expect that in an image with an build Date of Jan 16, 2025 these fixes to get SPI to work are included? >I don't know why you copied a dtbo to /usr/lib/linux-image... Because I have very very basic understanding of the device tree. My thinking was, I do a sudo find -name *.dtbo -printf "%c %p\n" And see where the original files are ( that need to be changed). As I did not know what file are used during boot, I changed them both of them. I am still not really sure if you can replace these files on the sdcard and expect that they are used during boot. Is my expectation correct that I can just replace them on the sdcard and reboot, or do I need to rebuild and kernel/image ? What shows up in ls /dev/spi* ? /$ sudo ls /dev/spi* ls: cannot access '/dev/spi*': No such file or directory adif did get it to work and you can see that pin 24 if configured different. $ gpio readall +------+-----+----------+--------+---+ H616 +---+--------+----------+-----+------+ | GPIO | wPi | Name | Mode | V | Physical | V | Mode | Name | wPi | GPIO | +------+-----+----------+--------+---+----++----+---+--------+----------+-----+------+ | | | 3.3V | | | 1 || 2 | | | 5V | | | | 229 | 0 | SDA.3 | OFF | 0 | 3 || 4 | | | 5V | | | | 228 | 1 | SCL.3 | OFF | 0 | 5 || 6 | | | GND | | | | 73 | 2 | PC9 | ALT6 | 1 | 7 || 8 | 0 | OFF | TXD.5 | 3 | 226 | | | | GND | | | 9 || 10 | 0 | OFF | RXD.5 | 4 | 227 | | 70 | 5 | PC6 | ALT5 | 0 | 11 || 12 | 0 | OFF | PC11 | 6 | 75 | | 69 | 7 | PC5 | ALT5 | 0 | 13 || 14 | | | GND | | | | 72 | 8 | PC8 | OFF | 0 | 15 || 16 | 0 | OFF | PC15 | 9 | 79 | | | | 3.3V | | | 17 || 18 | 0 | OFF | PC14 | 10 | 78 | | 231 | 11 | MOSI.1 | OFF | 0 | 19 || 20 | | | GND | | | | 232 | 12 | MISO.1 | OFF | 0 | 21 || 22 | 0 | OFF | PC7 | 13 | 71 | | 230 | 14 | SCLK.1 | OFF | 0 | 23 || 24 | 0 | OFF | CE.1 | 15 | 233 | | | | GND | | | 25 || 26 | 0 | OFF | PC10 | 16 | 74 | | 65 | 17 | PC1 | OFF | 0 | 27 || 28 | 0 | ALT2 | PWM3 | 21 | 224 | | 272 | 18 | PI16 | ALT2 | 0 | 29 || 30 | 0 | ALT2 | PWM4 | 22 | 225 | | 262 | 19 | PI6 | OFF | 0 | 31 || 32 | | | | | | | 234 | 20 | PH10 | OFF | 0 | 33 || 34 | | | | | | +------+-----+----------+--------+---+----++----+---+--------+----------+-----+------+ | GPIO | wPi | Name | Mode | V | Physical | V | Mode | Name | wPi | GPIO | +------+-----+----------+--------+---+ H616 +---+--------+----------+-----+------+ Any tips that I can try ?
