Hi u-boot list,
I am trying to migrate the Hummingboard platform to DM_SERIAL. See below what I got so far. Booting this on top of master (as of commit 8bc87a4c5) shows nothing on the serial console. Next thing I plan to try is toggle GPIOs in entry code to see how far the code proceeds.
Any idea where to look before I go down that way?
Thanks, baruch
