I had done it directly in the device tree itself and didn't make an overlay then. But will this time around
-
The only difference between the boards is the SRAM, so the same overlay should just work on the pine64/64+, unfortunately I don't have access to a pine64+ at the moment to be able to test it.

Hi
I've just started work on the 5.4 kernel, will be testing that and getting relevant DTB changes into the patches. Once completed and working, I'll package things up as an overlay for those that want to use the MIPI-DSI.
If I get a chance to afterwards, I'll have a look at the dev branch to get something working there.
-
Hi, You'll need to remap the changes to the Pine64So device tree into the Pine64's, then you should be good to go.
The only major difference between the two is the dram, which is handled at spl/u-boot level.

Are the ribbon cables connected correctly, i.e. no misalignment etc.
[ 8.738486] sun6i-mipi-dsi 1ca0000.dsi: Attached device fy07024di26a30d
show's that it's attached the display unit.
I didn't have to add/change anything after booting up, ie no need to change armbianEnv.txt

I'm currently looking into a new project which will use (hopefully) the Rpi Waveshare hdmi based 4" lcd touch screen, linked to the pine64/Sopine
I'm at research stage, and will be looking into using a current 5.x kernel.
If anyone has any info on the waveshare lcd's I need to watch out for or suggestions to get further info (specifically the touch driver side), please post a response.
Progress on the project will be posted here, links will be added once I have some basics running.
This can hopefully open up the waveshare displays to other devices.
@Igor Yes I've read This post but am willing to do what I can to get Armbian to support the displays as best I can.

1. Looks like 5.6 mainline will contain all but HDMI Audio and MsgBox. Are we likely to have an official build based on 5.6 shortly after that becomes available?
2. Using the vagrant build method I tried cloning first just Gavinb's v9-a64-dsi branch, but got an early error in compile.sh when trying to create the config file
Should we clone the whole repo then point build at the specific branch? If so, how do we do that?
1 - Can't say how Armbian itself will move forward, as this is a specific branch for my requirements.
2 - Haven't worked with vagrant, so can't answer. Not that this branch has, and probably will remain fallen behind Armbian master.

Update - Touch panel is now working :)

@karlitos Hi, haven't made any progress the last 2 weeks, am on leave for holidays and only return on the 13th Jan when I can catch up on other test's that are being done during this time by someone else. He's currently checking through other kernel builds, so will generate patches once we can comfirm we have things workings on the I2c side.
-
I've already verified with i2cdetect, without loading the touch driver, using the normal overlay method, results are the same for both I2c-0 and 1

Thanks @pszypowicz problem I'm having is getting the I2C lines unlocked
[ 9.381132] i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0 [ 9.381155] Goodix-TS 0-005d: i2c test failed attempt 2: -110 [ 9.409109] Goodix-TS 0-005d: I2C communication failure: -110I have commited some debugging checks into the kernel, will be continuing with it today, after I sort out mac-addr issues I'm experiencing here in the office for the network changes we've had.
Image does work on the pine64, by adding in a patch to copy the sopine-baseboard.dts over the pine64.dts, should do the same on overwrite of the pine64-lts.

Finally, something that's actually displaying something now :)
Armbian build script https://github.com/GavinBa/build/tree/v9-a64-dsi
Kernel used https://github.com/amarula/linux-amarula/tree/v9-a64-dsi
I haven't tested everything as yet, aim was to get the display at least running.

Hi Igor
Thanks for responding.
I had already including most of that patch, however had missed /arch/arm64/Makefile changes which I've added.
Rebuilding and will continue to debug from there.

Hi
I'm jumped into this, using the above mentioned kernel https://github.com/amarula/linux-amarula/tree/WIP-A64-DSI and trying to run it on a Pine64-Lts (Sopine) board.
I have the Pine64 7" Lcd display which I'm trying to get running on the pine board.
I've patched the kernel to get the dtb's into a deb file and installed into the image.
However I'm getting a Bad Linux ARM64 Image Magic from u-boot when trying to start the kernel.
I've also noticed that the DT_fixup_script is failing on bad format as well.
Patchwork I've already done can be found here https://github.com/GavinBa/build/tree/amarula-WIP-A64-DSIIf anyone could suggest what I should be looking for to resolve the issue, I'd appreciate it.
Gavin

Not sure about working with v3.10.y of the kernel, as am working dev level on 4.14.y (However I locked it at 4.14.59, for beta purposes).
What I can tell you is we've been doing our own custom board, based on the R18/A64 with lpddr3 ram, so Sopine is the dev board.
I did do some tests today, working on figuring out why cpu_freq scaling is not working, (Can post image caps later, not at work atm), and went through the following:-
Downloaded and run Armbian script to build a fresh image Pine64so, Cli, Next, Stretch. Flashed onto an sdcard, and &^%$ it didn't boot.
Looked at the script, and yes U-Boot is 2018.something, so reverted it to 2017.11 as the tag, and rebuilt it, (again after adding 'debs' back to the clean level)
And what do you know, it boots this time, however Cpu_Frequency scaling still does not work
I'm compared the Kernel config files between a working system, being the OrangePi Zero with what I have for the Pine based board, not much differences other than the order everything is in.
Anyway, there's my bit in here to current known issues.

Hi, yes we have.
Just to update as well, we have managed to got the phy to respond to processor at uboot level by slowing down the MDC clock.
Found a reference path https://lists.denx.de/pipermail/u-boot/2017-February/281613.html
our u-boot 2017.11 did not have the MDIO_CMD_MDC_DIV_128 definitions and setting up miiaddr |= MDIO_CMD_MDC_DIV_128 resolved the clock issue.
Our next step is to resolve why the phy isn't transmitting data

I am currently developing a custom board which is based of the Pine64/Pine64-R18 dev board.
I previously had an issue with the ethernet not working at u-boot level using the sopine based R18 board, this I resolved by patching u-boot with the relevant emac sections that were missing from the device tree.
On the custom board we have used the R18 processor with the LAN8720 ethernet-phy chip rather than the RTL8211 used by the pine, and can't get the ethernet to initialise.
We have checked rmii clock timings etc and compared the custom board to the Pine and have noticed the following:-
MDC has been measured to be running at 18.6Mhz, resulting in 53ns pulse periods, on both our custom and the pine64 board.
The minimum MDC clock period for both the lan8720 and rtl8211 however is 400ns according to datasheet.
The ethernet is not working on the LAN, yet it is on the RTL.
It seems the RTL is capable of running at that speed, although spec is 400ns, but the LAN is conforming to it's spec.
Any ideas on how to slow this clock speed down to the minimum 400ns period would be appreciated.

You probably need to level shift your voltages.
The orange pi has 3.3v signals, and your rs232 converter is most probably a 5v device.
Try looking here http://www.hobbytronics.co.uk/mosfet-voltage-level-converter for a simple level shift circuit.

I agree the pins are used for the WiFi module, however I do not have a physical device connected. I am in the process of trying to isolate those pins from it.
However there seems to be a different issue that's arisen with the current merges going on, in the sense that the working PB based overlay, tested in 4.14.41, causes the board to go into kernel-panic mode when the kernel starts up on any newer version, I.e 42 and 43.
I'll open a different thread for that after a bit more testing, as this can wait until we start piecing everything together in the project with it own full device-tree.
A64 - Efuse - Driver patch
in Off-topic
Posted
Hi
We've made a patch for the current a64 megous 5.10 kernel which enables writing to the 2K SID/Efuse security area of the A64/R18 processor.
Our initial investigations have found that the A64 doesn't seem to match the tables found in the SID Register Guide, however we've proceeded to perform various write tests and are presenting our results here for anyone that may found it useful in further development. There shouldn't be any issues using the same patch in the 5.14 kernel, as the driver code is still the same. The patch won't be pushed upstream, and is for dev purposes only, as the original intend of the driver is to be read-only. (This is EFUSE area
)
The armbian branch with the patch is on github
Our tests have resulted in some erratic behavior with the registers as has previously been reported by Icenowy during her tests.Additionally we have only found a total of 32 fragmented bytes that we've been able to write to.
A reply to this post shortly will show a map of the writable efuse area that we found.
