1900ACv1 still not functional.

"iptables" once again has output "illegal instruction" ("xtables-legacy-multi iptables" has the same output).

Before you say "USE iptables-nft INSTEAD!", that executable is *not* in the 63485 build for 1900ACv1. However, it *is* in the 63485 build for 1900ACv2...not sure if that means anything.

/dev directory continues to have almost nothing in it. dnsmasq fails to start because /dev/random doesn't exist. It looks like the MTD devices are getting created:
Code:
/usr/sbin # ./mtdinfo
Count of MTD devices:           11
Present MTD devices:            mtd0, mtd1, mtd2, mtd3, mtd4, mtd5, mtd6, mtd7, mtd8, mtd9, mtd10
Sysfs interface supported:      yes

But, no /dev entries are created for those.

dmesg output is attached.

I will forward again. It would've been nice to have output of cat /var/log/messages as well as the output of all commands in a text file as well. I was told last time that it was the same image as the rest of the devices, but image sizes are not the same for V1 and V2.

i can only assume a compiler bug here since the armadaxp cpu has less registers than the cpu used in the v2 models
