Buildroot RCM image

RCM loading

It is possible to boot paz00 into Buildroot in RCM (APX) mode from host PC with.

Starting from U-Boot v2014.07 tegra-common-post.h contain changes for distro loading, which disables initrd relocation:

...
 "fdt_high=ffffffff\0" \
 "initrd_high=ffffffff\0" \
...

this is breaks initrd image loading by kernel, error in dmesg:

...
[    0.000000] INITRD: 0x00540040+0x014a5523 overlaps in-use memory region - disabling initrd
...

To fix it we need to override this variables in RCM image script, boot.scr:

...
setenv initrd_high''
setenv fdt_high ''
...
