QEMU command line for running evb-npcm845 image

[Stefan Berger]

Hi!

   I am assuming that running the 64MB image with qemu-system-aarch64 is 
possible somehow, but I wasn't able to run it:

$ /usr/local/bin/qemu-system-aarch64 --version

QEMU emulator version 8.1.2 (v8.1.2)

I get now output with the following line where I am pasisng size=32M for 
the image, which is probably wrong anyway:

$ /usr/local/bin/qemu-system-aarch64   -machine npcm750-evb -nographic 
-no-reboot    -net nic -net 
user,hostfwd=:127.0.0.1:5722-:22,hostfwd=:127.0.0.1:5743-:443,hostfwd=udp:127.0.0.1:5723-:623 
-drive 
file=./tmp/deploy/images/evb-npcm845/obmc-phosphor-image-evb-npcm845.static.mtd,format=raw,if=mtd,size=32M

qemu-system-aarch64: warning: nic npcm7xx-emc.1 has no peer

CTRL-A + X  terminates it as expected.

With size=64M I don't get very far:

$ /usr/local/bin/qemu-system-aarch64   -machine npcm750-evb -nographic 
-no-reboot    -net nic -net 
user,hostfwd=:127.0.0.1:5722-:22,hostfwd=:127.0.0.1:5743-:443,hostfwd=udp:127.0.0.1:5723-:623 
-drive 
file=./tmp/deploy/images/evb-npcm845/obmc-phosphor-image-evb-npcm845.static.mtd,format=raw,if=mtd,size=64M
qemu-system-aarch64: device requires 33554432 bytes, block backend
