Yes. Please wait. I was busy with other personal projects, so I haven't been doing armbian stuff for a few weeks.

Driving the ili9488 LCD (4.0 inch cheap chinese clone)
robertoj replied to robertoj's topic in Allwinner sunxi
I don't know what you could improve right now... But I know that LCD only receives data. My LCD works the same, with its MISO pin connected or disconnected. -
Yes, that's a typo. The dc (data/command) should be PC7, and the MOSI (LCD's SDI) is PH7

OrangePi Zero LTS ili9341 TFT LCD (and later OrangePi Zero 3)

Yes. Probably this week. -
Is your LCD at least turning white on powerup? Did you connect the "LED" pin in the LCD, to 3.3V? Send a drawing of how you are connecting the LCD to the orange pi zero 3.

Thank you Pearo, What does "S/N" mean? I just ended up using my orange pi zero 3 gpio without the additional DTS, which made connector numbering available in the gpioinfo command... There were comments that made it sound not really necessary, and it was more work than I wanted to take on. The solution for me was: https://forum.armbian.com/topic/33800-orange-pi-zero-3-gpio/#findComment-181191 This was 2 years ago, and I haven't even thought about it, all this time.

Great I thought RiscV was still much slower than ARMs of similar prices.

I got surprised by "GPU: Mesa llvmpipe" ... but then I searched, and it means CPU rendering. But still very nice!

I just thought that a inserting a cpio file would be accepted, just like inserting a c file into the linux source code. I have never done a source file insertion myself, with neither C or cpio file... but I assumed it would work, since it is a common need for linux patches. In this page, they talk about the "--new-file" feature of the diff command https://unix.stackexchange.com/questions/37287/how-to-include-a-new-file-into-a-patch

Thank you guys for the work toward this RiscV SBC The website http://www.orangepi.org/html/hardWare/computerAndMicrocontrollers/details/Orange-Pi-RV2.html claims 130% faster than ARM A55 (which is 25% slower than my H618)... have you tested that? Are the USB, GPIO, SPI and MIPI DSI working? Are there any NPU examples provided by Orange Pi?

I missed the fact that you have an orange pi zero 2w... I think there's a success experience with that orange pi in this thread or in this Allwinner section. Please share if you have success -

Hi Pami, I haven't had time to check your connection list and DTS. The LCD you showed is exactly the same I have I have both ili9486 and ili9488, and they work with the same connections, same DTS, same bin, same driver You should be able to copy all the wiring I describe in the DTS, the DTS, bin/txt and armbianEnv.txt line, and it should work. Start from a fresh self-built armbian OS, with the panel-mipi-dbi driver activated in the linux config phase. -
A long time ago, I made an armbian guide, which included adding a kernel patch. Can you try this method? "Move them* to ~/armbian-2023.05/build/userpatches/kernel/archives/sunxi-6.1 (using the scp command or sshfs)" * would mean the cpio file (use diff3 to convert to patch file**) and any linux configuration patches needed to make your initramfs. ** diff3 linux_orig_source_folder linux_source_folder_with_cpio_file https://github.com/robertojguerra/orangepi-zero-full-setup/blob/main/README2.md#73-add-the-tv-encoder-driver-to-the-linux-kernel-source
