Is anyone doing anything special to get into the uart of the R2S? I know the baud rate is 1500000 I can not seem to get this to work on any device or any adapter so far. I have tried three different adapters and every time I try to access the R2S at that baud rate I just get garbage characters. I was able to adjust the baud rate in the OS I loaded however this means the uboot is still at that 1.5M. Any tips or info would be very helpful!
Note: the RPi4 in question is running aarch64, so the serial device may be different than expected.
Code: Select all
cu -l /dev/ttyS1 -s 1500000
