Hello.
I am new here.
I am running the Dec 22 9legacy on a machine, and now want to create a bootable
USB on it.
The USB is for a raspberry pi 4 4GB, acting as a standalone auth only.
But booting the pi always results in the error
- boot: can't connect to file server: '/boot/kfs' does not exist
I searched the mailing list for solutions, but had no luck.
To make my bootable usb, I used following script.
; cat mkusb
#!/bin/rc
iso=$home/tmp/9legacy.iso
#disk=/tmp/9legacy.rpi
disk=/dev/sdU0.0/data
sd=sdXX
dev=/dev/$sd
data=$dev/data
dos=$dev/dos
plan9=$dev/plan9
nvram=$dev/nvram
fossil=$dev/fossil
test -f /srv/9660 || 9660srv
mount /srv/9660 /n/cd $iso
# partition the SD card | USB image
dd -if /dev/zero -of $disk -bs 512 -count 1
disk/partfs $disk
disk/mbr $data
{echo a p1 0 8; echo t p1 FAT32; echo a p2 8 '$'; echo w} | disk/fdisk -b $data
{echo a nvram 2551 2552; echo a fossil 2552 '$'; echo w} | disk/prep -b $plan9
# format and populate the dos partition
disk/format -b /386/pbs -df $dos
rm -f /srv/dos.rpi
dossrv -f $dos dos.rpi
mount -c /srv/dos.rpi /n/dos
cp /arm/9pi4 /n/dos
# copy pi specific startup files
dircp $home/tmp/rpi4 /n/dos
# format the fossil partition
fossil/flfmt -y $fossil
