kobs-ng with kernel 3.19.x

1.) First you have to integrate the device detection according to

 

https://github.com/benavrhm/kobs-ng-patches/blob/master/kobs-ng-3.0.35-4.0.0_explicit_rom.patch

 

2.) Unfortunatelly the misc-dcpboot support were dropped with current kernel version. But you can replace drivers/crypto/mxs-dcp.c with an older version from from kernel version 3.14.

 

Now kobs-ng seams to by running well. The image validation works wih zero and otp written aes keys. (using kobs-ng option -z or -d)

 

But after reboot the FCB block is corrupted using kernel version 3.19.x. It works well with previous version 3.9.x. The FCB block is the only one written in non-eec raw mode.

 

Searching the community I found an entry regarding nand-mtd-gpmi driver using non-eec mode

 

http://lists.infradead.org/pipermail/linux-mtd/2014-September/055269.html

 

Are there any suggestions how to use kobs-ng with mainline kernel, where raw nand write works together with kobs-ng?

- any patches for kobs-ng

- any patches for the nand-gpmi.c driver

Birger
