Hi Kalyan,

At the moment the openrd image will only run if loaded into RAM through
openocd.

I'd discussed with Tanmay about running the openrd binary: I'd tried to
load it into RAM from the resident u-boot via TFTP, and that fails too.

In your case it will also certainly fail because the board config file
contains #define CONFIG_SKIP_LOWLEVEL_INIT, which as the name implies
skips very early and critical initialization code -- and without this
code u-boot won't start from Flash (this config option is used precisely
when running u-boot from RAM).

Can you try removing the #define and let us know if that fixes things up?

I'm not sure it will, though, because it fails when run in RAM from
u-boot with the #define, which means it probably does not do some
critical init --one that openocd does when it runs u-voot from RAM,
since in that case it works.

Amicalement,

Albert.
