Serial Output Garbage after initial messages
#1
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 ?
