Yes, this is what I tried before without success, but then I looked
again and realized… that I missed the option to choose the correct
output just below the “Kernel low-level debugging functions” option
because the text line was too long and I didn't see it chose
“EmbeddedICE DCC channel” by default instead of the UART. Big fail for
Still, no output.
Oh, and that was it! Why isn't it selected by the DT config? I see that
it's in the defconfigs, but selected nowhere by any option. Is there a
particular reason for this?
Then I saw the kernel log, I witnessed that it worked well, it just
couldn't find a root fs (I was booting with dummy parameters). So the
DT I made is actually working!
Thanks for your help, the patch will be following,
