Hello everyone,
I tried to install OpenBSD on Raspberry Pi 4B.
Flashed UEFI firmware onto sd card and OpenBSD on Flash drive.
I used https://github.com/AshyIsMe/openbsd-rpi4/blob/main/README.md
for step by step installing.
It booted into OpenBSD bootloader terminal, typed "set tty fb0" and
typed "boot" after ~10 seconds it just throwed blank screen,
The lights on my RGB keyboard stopped.
Is there any way to fix it?
Best regards,

I recently reformatted my RPI 4b. It was a relearning process. What
worked for me getting OpenBSD on the thing was dd'ing the image on the
sdcard and booting with UART console. I have a USB to UART adapter I
believe it is a CP2102 kind. You connect it to ground (there is several
grounds on the pinout) and TX and RX pins for UART0. Make sure it's
_not_ in 5V mode, and if you happen to switch TX and RX there is no
output. In this case it's not bad, just swap them and reset. Here is a
link to the pinouts of a raspberry pi: https://pinout.xyz/pinout/uart
it is indicated here that the GPIO pins for TX and RX are 14 and 15.
In general it's good to have a CP2102 in the household. They aren't
very expensive. I have also found that while working on a BL808 riscv
board that short circuited ESP32 which has a builtin CP210X also would
work. One day I'll return to getting the Ox64 (BL808) to try to get it
working again, and I'll use these.
Good luck!
