We have procured some units for integration.
No, I tried sudo dd if=/dev/zero of=/dev/fb1 and then sudo dd if=/dev/urandom of=/dev/fb1, everytime I made any change. oled never shows anything.
We have completed the integration of the SPI version of the ssd1306 to libretech-wiring-tool and the I2C one as well.
Which precise product are you using?
Updated the repo and tried the latest dts files. It is still not working by using dd command.
I tried it with my raspberry pi many times with no sweat.
Anyway I will turn to oled ili9341 as I found the resolution of ssd1306 is too low. I need to show lots of chinese characters on the oled screen and the smallest ttf I can find is at 8 pixel. The ssd1306 cannot suffice as it cannot present the entire clean content.
I will be glad to assist any test for ssd1306 if needed.
sudo dd if=/dev/urandom of=/dev/fbX bs=2
If the block size is larger than the buswidth, the transfer will fail and nothing will change on the display.
Can you provide a clearer picture of your GPIO wiring?
Both the ILI9341 and ILI9486 are already tuned for this board. If you need higher resolution, you can also consider the ST7735R and ST7789V. ST7789V does not support the DRM interface yet though, only FBTFT.
Thank you for taking time.
I tried it to both ssd1309 and ili9341, still not working.
For GPIO pictures, 7 lines with 7 different color. The oled in the picture is ili9341.
Relevant cmdlines are,
sudo ldto enable spicc spicc-ili9341
sudo ldto merge spicc spicc-ili9341
sudo reboot

By and large, the current situation is I still cannot make either the previous ssd1309 or the ili9341 to present anything by using fb device. The oled screen is never intended to be used to show the system output or desktop.
I’m trying to use it to show some information such as Chinese lunar calender and that’s it.
Did you move the jumper for the ILI9341 display? Without the jumper change, it will not display anything.
Also with regards to your previous screen where the corner was showing white static, it’s actually working.
- The reason for the static square is that the width/height are flipped. There’s a secondary problem of addressing.
- The fbtft does not have a way to configure the addressing mode or start offset and the display area is on the other side of the buffer. For example, the st7789 has a 240x320 buffer, but the LCD is only showing 240x135 attached to the wrong end of the buffer.
- The way to fix it with fbtft is to set the screen size to the full display area of the chip with the LCD only showing the half of the display area. This has the problem in that Linux will think the unshown half is shown.
- We are working on a DRM solution for this problem so we can skip fbtft’s limitation.

Yes, then reboot. Also do not put heatsinks on DRAM. They don’t need it.
Thank you. I removed the black heatsink from dram. The oled is not working.
Is the ILI341 working?
The ssd1306 overlay was tested against the display without CS. For your display, it might need to be tweaked. Do you have the link to where you bought it?
ili9341 not working, I will get back to take a close look later. I still think it’s pretty close to success, only I’m not familiar with the usage, I guess. I’m planning to test it on raspberry pi firstly to make sure it is fine.
For ssd1309: https://m.tb.cn/h.5203giw?tk=kcmndEifDdn
They send me the spec issued by solomon technology just those ones can be googled. If needed, I can send it to you later.
For the OLED, did you change the compatible ID to match your display?
For ili9341, I applied the dts file “spicc-ili9341.dts” written by your team.
For ssd1309, I simply used compatible ssd1306. The major difference between the two is the oled size, one is 0.96’‘, the other is 2.42’', so I didn’t change anything in the file “spicc-ssd1306-128x64.dts” and directly applied it.
If you don’t switch the compatible, it send the wrong parameters over SPI since the clocking is different.
ILI9341 should work as it’s been tested against a few screens already.
