reTerminal - Raspberry Pi black screen problem

Products & Technology Raspberry Pi
#1

Hi,
I have confirmed a problem with the screen not displaying on certain Raspberry Pi OS versions, even with the latest reTerminal driver.

  • 2023-05-03-raspios-bullseye-armhf.img.xz
  • 2023-10-10-raspios-bookworm-armhf.img.xz
  • 2023-12-05-raspios-bookworm-armhf.img.xz

So I tried modifying the driver script.
Would you all like to try it?

If it works properly, please click :heart:(“like this post”).
If it fails, please let me know the image of the raspberry pi os you used and the steps to reproduce it. :pray:

Summary

  • I will modify the operation for Raspberry Pi OS. Unchanged for Ubuntu.
  • For Raspberry Pi OS, --keep-kernel option recommended. (DON’T upgrade the kernel.)
  • Raspberry Pi OS 64-bit kernel + 32-bit userland is NOT supported. (Change to 32-bit kernel + 32-bit userland with arm_64bit=0)

reTerminal unable to install Raspbian 64bit and get LCD drivers to work
New reTerminal, powers up with blank screen

This worked for me, all sorts of issues with blank displays. One thing I did need to do was pull the power out after the install, a reboot did not bring the screen back. Great work ! Running Bookworm (the Seeed supplied version, which did not enable the screen)

Hi @lakid ,
Thanks for message. I am very happy.:blush::smile:

Oh…
Could you tell me more details? I think I’ll try it out.

  1. Raspberry Pi OS image (e.g. 2023-12-05-raspios-bookworm-arm64)
  2. Did you apt upgrade before installing reTerminal Driver?
  3. What is the STM32 firmware version? (If you have installed reTerminal Driver, you can check it with dmesg | grep mipi_dsi. Latest version is v1.9.)

  1. 2023_11_15_bookworm_64.img
  2. No, the screen never worked with the image above. I followed your instructions from your branch on github and it all worked.
  3. [ 9.201813] mipi_dsi: (i2c_md_probe) STM32 firmware version 1.9

I’ve got an E10-1 expansion module and when that gets plugged in, the display doesn’t work and I get a ton of
Feb 09 10:39:42 reTerminal kernel: i2c-bcm2835 fe804000.i2c: i2c transfer timed out
in the logs
but thats another issue to tackle
thanks !
