ag123 Posted May 8 Author Posted May 8 @OttawaHacker connect to the board using a usb-uart (debug) serial dongle. the boot messages would normally show up there, or that if it booted to the prompt, you could login as root and run dmesg to see what goes wrong try also the other u-boot https://github.com/ag88/1.5GB_Fix_for_Armbian_on_OrangePiZero3/ to see if that helps. there is a sequence of patches that needs to be applied and I've done that with my implementation. Unfortunately, in my case I hardcoded the 1.5GB memory as I found that for 1.5GB boards, the mainline u-boot incorrectly detected memory as 2GB or 4GB inconsistently. For once it says 2GB, then 4GB, then 2GB, and the algorithm would probe into the wrong memory size. so 'hardcoding' it ensures that it is 1.5GB no more / no less. you can use the distributed Armbian images https://www.armbian.com/orange-pi-zero-3/ and subsequently apply the u-boot patch from my repository. If you don't use dd , you can try using the python script that I've provided in my respository to patch u-boot into the image. Checkout instructions in my repository. 0 Quote

Am I missing something? @OttawaHacker This is a minimal build, probably it has no HDMI output. As @ag123 said, you need a serial cable to see output. Or you could access via SSH, looking at your router for DHCP address. Other option would be to use a build with desktop like this one, and apply patch the same way. Any way, pull request was already merged, so you can wait for next community release in a few days. 0 Quote
voapilro Posted May 8 Posted May 8 @ag123 @OttawaHacker I saw community builds already generated here. I could check that they have u-boot DRAM patch, so I tried both of them in my board, and they boot normally 🙂 also minimal one having HDMI output. 1 Quote

bjorn Posted May 11 Posted May 11 It works, thanks @ag123, good work ! For some reason the Armbian Image is far slower than the Orange Pi Debian image in UI mode. I am guessing its maybe because the Armbian Image comes only with Gnome which is probably heavier UI framework to run. 0 Quote

TRay Posted May 13 Posted May 13 I would like to ask about the entry in armbiaEnv.txt in the ArmBian distribution for Orange Pi Zero 3 overlay_prefix=sun50i-h616 does it have anything to do with the file in the directory? /boot/dtb-6.6.30-current-sunxi64/allwinner/sun50i-h618-orangepi-zero3.dtb For OZPI version 3 there is a prefix sun50i-h618 and in armbianEnv.txt there is overlay_prefix=sun50i-h616 shouldn't it be sun50i-h618 ?? I'm asking about this because I have a problem with using overlay for w1-gpio for OZPI v3, so I am looking for the source of the problem in various places 0 Quote

It is a warning about what something sees as an invalid or incomplete configuration in Device Tree, rather than a real problem with the hardware. 0 Quote
D Posted June 1 Posted June 1 (edited) Hi! OrangePi Zero 2w user here: I'm trying to understand why there is no `pwmchip0` in `/sys/class/pwm`. I'm using the latest kernel 6.6.31 with an extra dts overlay. I noticed that there is uart5 enabled by default, so I should see `pwmchip0`, right? Was there any regression reported? EDIT: also, why is there a definition for pwm5 when it does not exist? Edited June 1 by D 0 Quote
ag123 Posted June 1 Author Posted June 1 @D answer to that question is 'complicated', there are a bunch of DTS patches https://github.com/armbian/build/tree/main/patch/kernel/archive/sunxi-6.6/patches.armbian which are laid on top of mainline H616 DTS https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/boot/dts/allwinner/sun50i-h618-orangepi-zero3.dts https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/boot/dts/allwinner/sun50i-h616.dtsi you can try to decompile the dtb file back to its source to examine it dtc -I dtb -O dts -o ~/devtree.dts /boot/dtb/allwinner/sun50i-h618-orangepi-zero3.dtb 0 Quote
D Posted June 1 Posted June 1 Thanks for replying @ag123. I don't negate the fact that my dts might be broken (review below), but why can't see `pwmchip0` in `/sys/class/pwm`?

ag123 Posted June 2 Author Posted June 2 @D I'm really unfamiliar with DTS and such, hence there isn't much I'd help. But that are there any hints in dmesg etc? And as I suggested, try to decompile the dtb for your board and review that. In my case, I tried that for Orange Pi Zero 3 and did not see pwm devices listed. Hence, I'd guess those would need to be added by applying a .dtbo (device tree overlay binary). Accordingly, you may be able to check the same thing in a running system by checking them under /proc/device-tree as well. e.g. if you don't find them in /proc/device-tree, maybe that overlay isn't loaded. 0 Quote

Stefal Posted June 11 Posted June 11 Hi! Thanks for all the work on this board! I noticed that a reboot do a power cycle on the usb peripheral connected on the usb type A port. But not if I use the usb pins on the 13 pins header. Is there a way to enable a power cycle too ? I'm afraid it's not possible because the 5V pin is a in/out pin, but I prefer to ask. 0 Quote
Norite Dev Posted June 13 Posted June 13 Hi! Thanks for all the efforts! Was wondering is there a real GPU Mali support in the latest build? Can anyone tried to compile opencv (openCL) with GPU support? 0 Quote
ag123 Posted June 14 Author Posted June 14 well h618 isn't a 'high performing' cpu, so don't expect too much in terms of opencl etc, probably nil. and even GPU support is probably sketchy https://docs.mesa3d.org/drivers/panfrost.html https://bakhi.github.io/mobileGPU/panfrost/ https://en.opensuse.org/ARM_Mali_GPU GPU is a most undocumented aspects of these socs, many time you are left with 'you are on your own', no docs, no help, no hints, no nothing you can try plain old NEON https://developer.arm.com/Architectures/Neon https://developer.arm.com/documentation/dht0002/a/Introducing-NEON/Developing-for-NEON/Automatic-vectorization this would probably 'just works' 0 Quote
burger242 Posted June 16 Posted June 16 Hello, first post here. I have recently bought an Orange Pi Zero 3 4gb (its my first approach to any IoT so im quite noob), and i cannot make it work using armbian. Ive read a lot of users having troubels regarding the 4gb one, but I couldnt even make it reboot by following the "chinese" github. Generally, it boots the first time fine, but from then it has errors. I was wondering if you could please help me. Ive tried different armbian versions but nothing seems to work. Thanks. 0 Quote

What exactly have you tried so far? How are you determining it's not working? What kind of SD card are you using, and how are you installing Armbian on it? What are you using for a power supply and USB cable for power? What's the behavior of the status LEDs? Are you using a keyboard and monitor, or are you connecting to the board via SSH? Have you tried attaching a serial cable to it and reading the output over a serial terminal? 0 Quote
burger242 Posted June 20 Posted June 20 At first I thought I was having troubles installing Armbian in my Orange Pi Zero 3 4Gb. However, I have also tried Ubuntu, Debian and Orange Pi OS and none of them work. This is what I mean by not working, also including the process I usually follow: Format my 2tb Lenovo SD card, recently using SD Card Formatter Try to install the SO both using Balena Etcher and Win32DiskImager Insert and boot the Orange Pi. First and second/third boots work, usually after that it gives different errors when not booting, usually: "/dev/mmcblk0p1 does not exist" The only thing I did on those boots was "sudo apt update && sudo apt ugrade -y". Also, "sudo dpkg-reconfigure keyboard-configuration" to change the keyboard layout to Spanish. I am using a 5V 3A power supply. Leds are red when starting and then turn green; blinking. Im using a keyboard and a monitor I am not able to try a serial cable. PS: When trying with Armbian, i tried this Armbian Github, following the steps for 4GB. This is my Lenovo SD 0 Quote

Where do I get them for 4gb then? Is there any kind of tutorial/guide? Thanks Edited June 20 by burger242 0 Quote
