Hello,
The note was intended to remind everyone about the additional steps required when installing a 32-bit OS, ensuring that users can use it properly.
The content related to the reTerminal series on our Wiki has been thoroughly tested and verified to be accurate. If you encounter any issues while using the reTerminal, you can find answers in our FAQ section.
We appreciate your interest in and support for our products.
Hello @Seeed_Seraphina,
When I install the OS provided in the wiki I directly have the driver to control the screen and all the reTerminal sensors, but when I update the OS it overwrites the driver and so I no longer have access to the sensor data, and the screen no longer lights up. When I install the driver manually as described in the wiki, it still doesnāt work.
The only time it works is when you install the unmodified OS, and then you have access to the screen but no longer to the sensor data and the dashboard to see the sensor data, which is a problem for me, as I bought the reTerminal for the screen and sensors.
Is there another way to update the bone provided in the wiki, without the update overwriting the driver.
Oh I see. Iāll discuss it with my colleagues.
Interesting, I am experiencing the same issue with the reTerminal as the original poster.
Attached is the log of the errors, and a repeat of the issues above.
No joy ā¦ still a blank screen.

Wow, Nice work!
I am AMAZED at how they (seeed) nurfed this product execution UP 
. No doubt with TERRIBLE software/firmware installation and implementation. a very BASIC thing like "Apt, Get, Updateā¦WTH?
I certainly hope they get it figured out and solved B4 I order one FORSURE!!!
Itās a Very Nice piece of Hardwareā¦ Lotās of options and interface capabilities.
I do Understand there was an intension for a user to define OS. and install it.
Roll your own , so to speak. FAILā¦
SEEED , needs to Inform the users on the Wiki of the previous debacle and Layout a clear repeatable procedure to Un-screw this Light bulb. and fix any prior to shipping!

Can you contribute this to the upstream provider? They must not know about this issue.
I completely agree.
I will make a request to Seeedās reTerminal Team. 
Thank you for confirming.
Iām glad itās working well. 
I will make a request to Seeedās reTerminal Team.
I tried a second machine and found it was not working. I will need to dig deeper to find out what might be causing the issue.
For those following along, the git clone command I used was from @takashi 's own repository:
git clone --depth 1 https://github.com/matsujirushi/seeed-linux-dtoverlays
Hi @beadon ,
Ohā¦
Could you tell me details?
cat /boot/firmware/config.txt or cat /boot/config.txt
lsmod | grep mipi_dsidmesg | grep mipi_dsiYes, let me get back to you shortly. The device is far away. I also suspect youāre right that the kernel modules may have been loaded incorrectly. Its possible that the kernel modules from an old attempt may be sitting around and caused issues when this (new) fix was applied.
I have reached out to an engineer closer to the device to snag this information on our behalf.
Thank you! I have struggled with this for two years. I had put this on āback-burnerā until now, when I tried one more time. 03/13/2024.
This step actually worked for me!
Thank you again.
Hello, our engineers are reviewing and addressing this issue. If there is any result, we will reply in this post as soon as possible
Ok, I have this information now. It looks like there might be a problem with I2C ?

I appreciate your assistance !
Hi @beadon ,
Thanks for information!!!
mipi_dsi 1-0045: I2C read id failed: -5
reTerminal-bridge dtoverlaydtoverlay=reTerminal-bridge to check?No, the reTerminal E10-1 expansion is not in use, we do not plan to use it.
ā /boot/config.txt line disabled, rebooted.
also commented reTerminal to check i2c. ā¦

Attempting to set the STM32 device into boot mode ā¦ nothing ā¦
sv@raspberrypi:~ $ sudo i2ctransfer -y 1 w2@0x45 0x9b 0x01
Error: Sending messages failed: Remote I/O error
However, confirmed that we probably don;t need to update the STM32 based on this mapping , showing what I believe is the latest firmware , according to the guide:
sv@raspberrypi:~ $ i2cdetect -y 1

Have now uncommented :
dtoverlay=reTerminal,tp_rotate=1
and restarted. still no screen turning on.
