Hello, Installed OpenBSD 7.9 on Raspberry Pi5. It seems to be working fine as long as I boot with a serial. If I try to boot without serial, I see the green light, even after ~5 mins, I can't SSH, don't see it in the network (checked the client list in the router).
Are you using the three-pin debug header on the RPi5 (https://pinout.xyz/pinout/uart, check the 'Pi 5 is the exception' paragraph)? If yes and it's stuck on the u-boot prompt then check out [1] which refers to [2] and setting 'bootdelay' to -2 may help.
I got the issue of garbage on the serial line when I'm not connected to the debug header. And that interrupts the boot process at the u-boot stage.
Setting bootdelay and save it got it booting. setenv bootdelay -2 saveenv [1] https://marc.info/?l=openbsd-misc&m=176934607925591&w=2 OpenBSD 7.8 boot stuck at U-Boot> prompt on RPi 5 [2] https://marc.info/?l=openbsd-arm&m=176840254723277&w=2
After successful boot with serial, I can unplug and let it run/connect over SSH. I'm powering the Pi with a 5 V / 3.4 A cable. Attached the dmesg and /etc/ttys content. /boot/config.txt (default): arm_64bit=1 enable_uart=1 dtoverlay=disable-bt kernel=u-boot.bin Didn't modify much other than library relinking at boot-time and ntpd flags: pi5# cat /etc/rc.conf.local library_aslr=NO ntpd_flags="-s" No /etc/boot.conf. Internet connection is over Wi-Fi. pi5# cat /etc/hostname.x join mynetwork wpakey *** inet autoconf
