I worked on the Giant Board some more today. Its lack of JTAG debugging is maddening. I can't get the console UART1 to work, so I'm not sure how to proceed. I'm just guessing, and swapping SD cards a lot. Urgh.
I think it has something to do with the device tree that the Giant Board uses with U-Boot. I can compile, debug, and run just fine on the SAMA5D2-XULT board. But the SD Card that boots that board into NuttX just gives me garbage on the serial line, maybe because of the clock divider being different. The SAMA5D2-XULT boot.bin and u-boot.bin don't use a device tree. If you have any ideas I'd like to know them. I'm stuck. -adam On Wed, Aug 19, 2020 at 10:55 AM Adam Feuer <a...@starcat.io> wrote: > Greg, > > That keyboard/screen combo looks pretty cool.
