Serial Output Garbage after initial messages

[jamforlunch]

Hi, 

I've been trying for 3 days to get an linux image to boot on my RockPro64 without any success. I followed the initial sticky forum message and ended up waiting a day for 0% downloaded from various servers. 

Then I found the latest daily images and used a boot installer by concatenating the FW and partition, and burning the img to an SD in linux with dd. I cant seem to get a new single partition SD card to boot, I only had success with an SD I had used with my Pi - that has 3 or 4 partitions on it.

Anyway the new May 2022 installer got to 100%, then I got a flashing cursor where I could type, rebooted and back to the installer again.  Also, has anyone actually got a RockPro64 to install Debian and boot to it in the last 3 months ? If so, was there anything you had to do apart from create the SD image, answers the installer questions and let it install ? 

For the serial UART output, I watch it with 115200 baud, and I can see the initial messages, then it starts outputting garbage. Any reason it switches like that ? Is the first part the rom/boot at 115200, and then does the baud rate change when its running the installer ?

U-Boot and the OS can have different baudrates, try 1500000 if you want to read the second part.

U-Boot and the OS can have different baudrates, try 1500000 if you want to read the second part.

Thanks for the info, changing the board rate didnt work though. Now I have switched to using a Debian install from mr fixit - its an old kernel version 4 from 2019 - but its the only one I got working. 

Do you know if the latest Debian works on the RockPro64 - with all its peripherals ?

[t4_4t]

The Debian installer does not install 'boot-loader (u-boot)'.
In addition, the partitioning tools included with the Debian installer
It also does not reserve space for installing 'boot-loader'.

In short, following the installer's instructions(recommended) does not create bootable media,
and if you try to install 'boot-loader (u-boot)' later, you don't even have space for it.

It's unclear what the '...The latest daily images used...' you claim specifically refers to,
but the above symptoms are the same for both 'Bullseye' or 'Bookworm '.

If you haven't installed a boot loader on your eMMC or SPI-Flash, the problem above is probably the wreckage of trying with a 'Ras-Pi'.

Creating an independently bootable media image requires some ingenuity to avoid the above issues.
