i.MX6Q Boot from NAND

i.MX6Q Boot from NAND

[andreas.willig]

Hi,

has anyone in the community successfully managed to get Barebox running out of NAND on i.MX6Q/DL? I cannot find any support for BCB / FCB in the BB sources and am hitting problems while migrating from i.mx28 (MXS?) sources of BCB. U-Boot seems to run from NAND on i.MX6Q but is not an option for our project.



Mit freundlichen Grüßen aus Berg/ With kind regards

So far I used kobs-ng for doing this, I didn't have luck with migrating
the i.MX28 BCB code so far. Somebody asked the same question a while
ago, but I can't remember who it was. He didn't report success so far
either.

Philipp has recently sent a patch which turns off the GPU clocks in
barebox. This could help a little. The path sits in -next right now.
