reTerminal unable to install Raspbian 64bit and get LCD drivers to work

danon · October 30, 2023, 10:17pm

I am unable to get Raspbian 64bit to install with the reTerminal display drivers to operate the LCD display propertly.

Here are the things I’ve attempted:

All the steps outlined in this forum topic reTerminal - blank screen after flashing OS ... again!
I have installed the original 64bit reTerminal image, the display does not work
I have installed Raspbian 64bit successfully so that the desktop is visible via the HDMI port and then have installed the drivers as outlined reterminal-dm-flash-OS/#install-drivers
When I tried to go through the STM 32 f;ash / version upgrade process as documented at eTerminal-FAQ/#q1-how-can-i-update-the-stm32-firmware-for-reterminal-lcd the command “i2ctransfer -y 1 w2@0x45 0x9b 0x01” returns “Error: Sending messages failed: Input/output error”
The command " i2cdetect -y 1" returns the following

If I flash the SenseCap Edge OS, the screen works fine, but I want a vanilla raspbian installation. reterminal-dm-sensecraft-edge-os-intro/

I’ve done about 8 flash installations so far of different raspbian images and simply cannot get the LCD screen to work by following the instructions. What would you recommend as next steps?

tasman · October 30, 2023, 11:26pm

Hello, I have also had a lot of trouble getting the screen working.
Getting the same errors when trying to upgrade STM32 chip firmware.

I had upgraded it before so i dont think that it is the problem, but i have tried everything else.
My screen now is on but will change to static flickering and then come back in an endless loop.
There is also no touch input.
I have had screen issues with 2 different ReTerminals.
Not tried a different OS though. Interesting that it works with the SenseCap Edge OS. I will try this as it will confirm that it is a software problem over a hardware problem.

Cheers

Hello everyone,

Regarding reTerminal, we would like to inform you that our official drivers are currently not compatible with the latest 64-bit or 32-bit images provided by Raspberry Pi Imager. Additionally, Ubuntu Server is also not supported.

If you intend to use Ubuntu, we recommend opting for Ubuntu Desktop (tested and fully functional on versions 22.04). For Raspberry Pi users, it is advised not to use version 6.1 and instead stick to the previous version 5.10

danon · November 6, 2023, 9:49pm

Are you referring to kernel version 5.10? I downloaded and flashed this version and the system will not boot Index of /rpd_x86/images/rpd_x86-2022-07-04

can you point me to an image that will flash successfully?

Seeed_Seraphina · November 7, 2023, 3:08am

It looks like you have selected a Raspberry Pi image for PC/MAC, which is why it won’t flash into the Raspberry Pi properly

You can download the image from this url:
https://downloads.raspberrypi.com/raspios_arm64/images/

In fact, kernel version 5.x works fine after flashing the driver! Here you can find the kernel version for each date:
https://downloads.raspberrypi.com/raspios_arm64/release_notes.txt

I tried the image shown in the picture, his kernel version is 5.10.92. After using driver, can successfully light up the LCD

tasman · November 8, 2023, 8:53am

Thanks for your reply, how can we ensure future updates will not break this?

Seeed_Seraphina · November 8, 2023, 9:31am

As of now, the mentioned images can all be used with the drivers we currently provide, and this will remain unchanged for the foreseeable future.
If there are any changes, we will also notify you on Weekly Wiki as soon as possible!

@Seeed_Seraphina I’m facing the same issue

Downloaded https://downloads.raspberrypi.com/raspios_arm64/images/raspios_arm64-2022-01-28/2022-01-28-raspios-bullseye-arm64.zip
Installed driver; for some reason they updated my kernel too

cd /tmp
git clone https://github.com/Seeed-Studio/seeed-linux-dtoverlays --depth 1
./scripts/reTerminal.sh

Before: L5.10.92-v8+
After: 6.1.21-v8+

After reboot, still no screen.

Whatever I do, I can’t get the dislay to work again.

I’m also confused why your script would move the kernel from 5.* to 6.* even though it’s not supported. Reported this on Github here.

EDIT: Tried again

EDIT

So, this is funny.

Out of options, I dissambled the device to check connections; Of course everything was just fine; Pulled-out the battery for a sec; Put it back together. Boot … Working.

Why?

Did that reset something?

Seeed_Seraphina · November 10, 2023, 3:35am

Hi, we still recommend you to use our 64-bit factory image. The factory image contains the required drivers and will solve the problem of the LCD not working!

tasman · November 13, 2023, 10:27pm

Hi, that is great news, but does this mean we cannot “sudo apt update && sudo apt upgrade -y” without first putting a hold on kernel updates? Are there any other packages that will need to be held also?

Or would we just have to manually update any individual packages that an updated application may require? If so, this will be very time consuming to identify.

Are there updated drivers being worked on? Currently due to the need for the device to function, i have the most updated Raspbian OS installed and all of my services are functioning, but none of the functionallity of the reTerminal, i may as well just have used a CM4 IO board and not purchased the reTerminal at all.

Seeed_Seraphina · November 14, 2023, 3:31am

We have made new updates to the drivers. We tested them yesterday, and as expected, the LCD can be used after installing the driver.

Maybe you can try again.

tasman · November 15, 2023, 10:35pm

Hi, this is great news that you have updated the drivers! I have performed the following steps

sudo rm -r seeed-linux-dtoverlays

git clone --depth 1 https://github.com/Seeed-Studio/seeed-linux-dtoverlays

cd seeed-linux-dtoverlays

sudo ./scripts/reTerminal.sh

And get this

Is it that i should be on a different kernel version?

tasman · February 1, 2024, 9:09pm

Hi,

Still the same issue 5 months later.
If i reinstall the OS to the seeed studio OS i will lose all my config, and even then it will only work until I sudo apt update && apt upgrade.

takashi · February 1, 2024, 11:30pm

Hi @tasman ,

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

tasman · February 5, 2024, 3:00am

Hello Takashi,
The install on 2023-12-05-raspios-bookworm-armhf.img.xz worked well.
Screen working, even showing less artifacts than when it has briefly worked before.
However, after a update and reboot it still shows up black

Version Info:
Linux fac-reterminal 6.1.0-rpi7-rpi-v8 #1 SMP PREEMPT Debian 1:6.1.63-1+rpt1 (2023-11-24) aarch64

Thanks.

tasman · February 5, 2024, 3:02am

Should i have not updated? I used the --keep-kernel flag on install, how do i prevent kernel upgrades from update commands such as apt upgrade?

takashi · February 5, 2024, 4:10am

Hi @tasman ,
Thanks for trying it.
Please let me know so I can try to reproduce it here as well.

What exactly did you do “after an update”? (Run “sudo apt upgrade”?)
It looks like the kernel is running on aarch64. Can you add arm_64bit=0 to /boot/firmware/config.txt and reboot?

FYI
I create the issue.

[2023-12-05-raspios-bookworm-armhf] after a update and reboot it still shows up black

tasman · February 28, 2024, 3:16am

Hello, apologies for the late reply.

It seems i was using the wrong image for 64bit.

I installed
2023-12-05-raspios-bookworm-arm64.img.xz
Install reTerminal driver (https://github.com/matsujirushi/seeed-linux-dtoverlays/blob/main/README_reTerminal_RasPiOS.md#install-script)

./scripts/reTerminal.sh
reboot
apt update
apt upgrade
reboot

The kernel is upgraded and the screen is showing.

I repeated this process twice as after the first time, there was a point where the touch panel stopped working, even rebooting would not get it to respond (screen still on, just no TP).
After repeating the above steps, it happened again but was fine after a reboot and hasn’t happened again.

Thank you very much!

mansson · March 19, 2024, 3:14pm

I’m happy for all of you who has successfully revived your reTerminal. I reflashed the STM32 according to instructions elsewhere, then performed the steps described by @tasman. Still blackness on both screen and HDMI. ssh still works, so I guess I will continue the struggle…

I think dmesg is trying to tell me something:

[ 6.642370] mipi_dsi 1-0045: I2C read id failed: -5

PJ_Glasso · March 19, 2024, 3:43pm

Hi there,
From lurking I think the I2C address you flashed is WRONG, that’s what it is dmesg too.
Run I2c scanner, what do you get? change it , then reflash again is working AFAIK, which ain’t much. I want to get one but I see a lot of people had issue’s with these things. seems like too much trouble.
