Kernel kills init

For Developers
1

I'm trying to run OpenWRT/LEDE on a sama5d3 xplained board.

So far, I have everything set up, but after booting the kernel, init fails to load.

Kernel panics, and the device reboots.

This is with OpenWrt GCC 5.5.0 r5932-9c4fe10.

Any help welcome.

hi leventelist,

we need some more information.
Is this a upstream Image or did you made some tweaks?
Are some additional hardware and kmod installed?

Thank you for coming back to me.

This is the same with the upstream SD-card image, and also with my own
built one.

https://downloads.lede-project.org/snapshots/targets/at91/sama5/openwrt-at91-sama5-at91-sama5d3_xplained-sdcard.img.gz

This is where I've downloaded the image. I've copied it to an SD-card with
dd.

The hardware is a recent D3 Xplained board. I don't really installed kmod.

Any help appreciated. Also, I want to port the whole thing to the SAMA52D
chip with internal memory.

Strange/Stupid question but did you gunzip the image and the made a dd?

Yes. Otherwise it would not even boot the kernel.
