Hi All,
I have progressed a little bit with the nano r6s. With the EFI EDK on an sd
card
and the file "install76.img" copied on an USB disk the installation was
possible.
To install it, I have to select DTB instead of ACPI in EFI Bios. The emmc card
is
not recognised but an USB disk and the sd card are available.
To avoid the problem of the lack of serial console, one can type
at the boot prompt of the loader of OpenBSD the command "set tty fb0".
However, once the installation is done, after a reboot, the serial console is
used again.
This could be avoided by typing the correct command at boot to switch to the
frame buffer
console but then, after the begin of the boot correctly displayed on screen,
the following message (approximately retranscribed) is displayed
"can't open /dev/console, device not configured".
By letting the boot running in the serial console, a problem seems to arise
since
the ssh port is never open (seen with the command "nmap -p 22 172.36.36.0/24").
Any ideas to solve this problem? Should one configure the console by
escaping to the shell before reboot? If this is the case, how to do that?
Thanks for your help,
