I am looking for help to resolve this error when booting from a properly formatted SD card.

This version of barebox and it's environment has been working well since it was last built on 1 Jul 2014.

Here what I did to get to this situation:

We needed to disable a debug option in the Linux kernel, and this was done through running:

$ ptxdist-2012.03.0 kernelconfig

and disable the option through the menu for CONFIG_USB_DEBUG

Then ran

$ ptxdist-2012.03.0 go

$ ptxdist-2012.03.0 images

and the resulting images are as follows (edited for brevity) and we only need the solo image

16 -rw-r--r-- 1 16352 Jul 1 12:14 barebox-default-environment

356 -rw-r--r-- 1 362703 Jul 1 12:14 barebox-phytec-pbab01s-512mb.img

31476 -rw-r--r-- 1 32230790 Aug 4 10:46 root.tgz

47232 -rw-r--r-- 1 48365568 Aug 4 10:47 root.ubi
45508 -rw-r--r-- 1 46600192 Aug 4 10:47 root.ubifs

Note as expected the linuximage and root.* binaries were regenerated. (I'm assuming the option to include the kernel config in the rootfs may have caused the rootfs to be re-built.

The modified images were then copied to an SD card and then I tried to boot from the SD card to ensure changes worked before flashing NAND (imx6s)

This is what resulted in the above message

mmc2: registered mmc2

barebox-environment environment-mmc.9: setting default environment path to /dev/mmc2.barebox-environment

envfs: wrong magic on /dev/mmc2.barebox-environment

no valid environment found on /dev/mmc2.barebox-environment. Using default environment

running /env/bin/init...

I have also tried using new SD card and still running into the same error.

I have verified that I can use another SD card prior to the change to the Linux kernel and that SD card will boot.

Is it possible that the bootloader (barebox) should have been rebuilt?

Any help would be much appreciated.

Regards,
