I picked up the PolarFire SOC Icicle Kit during the crowd funding phase on Crowd Supply I've been playing around with the hardware off and on since I got it,
After attaching with minicom manually a few times, I eventually found the script below, it comes from the seL4 Test o the PolarFire SOC documentation. It works pretty well, and uses tio (which I find much more pleasant to work with) instead of minicom.
#!/bin/bash tmux new-session -d -s 'polarfire-serial-dashboard' tmux split-window -v tmux split-window -h tmux select-pane -t 0 tmux split-window -h tmux respawn-pane -t0 -k "tio /dev/ttyUSB0" tmux respawn-pane -t1 -k "tio /dev/ttyUSB1" tmux respawn-pane -t2 -k "tio /dev/ttyUSB2" tmux respawn-pane -t3 -k "tio /dev/ttyUSB3" tmux select-layout tiled tmux set -g mouse on tmux attach-session -t 'polarfire-serial-dashboard'
I've also setup the scripts as a gist here: PolarFire SOC Icicle Gists
After getting everything figured out I was able to boot, attached to all of the UART serial consoles attached, and interact with the linux login.
I was a little excited at this point, so I announced my accomplishment to the world:
Finally got around to playing with my Polarfire SoC Icicle Kit. Screenshot is minicom attached to all 4 (!) UART serial debug consoles. riscv64 running linux for now, want to play with the seL4 port though. Maybe an attempt to port #serenityos? 😃 #riscv #polarfire pic.twitter.com/q9EF98NhF3— Brian Gianforcaro (@bgianf) November 26, 2020
