Hi Sascha,
Thanks for the quick response! I tried imx_v7_defconfig but it seemed
to be as ill-suited for what I am trying to do as
freescale-mx6-sabresd_defconfig.
What I am trying to get is an ELF file that I would be able to use
with DS-5 debugger by uploading it directly into RAM and also an image
that I would be able to supply to the build-in ROM bootloader.
Imx_v7_defconfig specifies TEXT_BASE as 0x0 which isn't much better
for the purpose of using DS-5 since that memory is mapped to boot ROM.
For now I just ended up setting it up manually to 0x10000000 in menuconfig.
Thanks,
Andrey
