Sorry for resubmitting this but yesterday I submitted without a subject...
I'm a CS student and I've used OpenWrt for years. I'm writing to this
mailing list because I'd like to contribute to the project by adding
support of the aformentioned device.
From what I can see, there's already an open PR
(https://github.com/openwrt/openwrt/pull/3762). I've merged the current
master into my fork (https://github.com/eutampieri/openwrt) and I've
built it. I can boot it from ramdisk but as soon as I flash the
sysupgrade I get this into the serial log:
>|Kernel panic - not syncing: No working init found. Try passing init=
option to kernel. See Linux Documentation/admin-guide/init.rst for
guidance.|
As far as I can tell, the init var isn't passed from the bootloader
(uboot), but how can I fix this?
Thanks to Benjamin Kallus we've found that the problem may lay here:
[ 0.433506] 0x000002280000-0x000003f40000 : "firmware"
[ 0.441125] 2 uimage-fw partitions found on MTD device firmware
[ 0.447182] Creating 2 MTD partitions on "firmware":
[ 0.452225] 0x000000000000-0x0000005c0000 : "kernel"
[ 0.458674] 0x0000005c0000-0x000001cc0000 : "rootfs"
[ 0.464437] mtd: device 12 (rootfs) set to be root filesystem
[ 0.471011] mtdsplit: no squashfs found in "rootfs"
When I download the mtdblock for rootfs, I get
