I got my Giant Board yesterday and worked on it for about an hour last night. I got the DBGU serial terminal working with U-Boot, and was able to make an SDCard that will boot to the U-Boot that comes with the Giant Board. I can fatload nuttx.bin. But when I run (go 0x20008040) nuttx doesn't boot. Doing the same sequence on the SAMA5D2-XULT results in nuttx booting...
The U-Boot version is different, so maybe the memory map is different? Or maybe the way U-Boot sets uo the chip? It's using a device tree set up for Linux. I also don't have an SWD debugger so can't debug right now. That's where things stand. If anyone has any ideas on how to proceed I would love to know them. -adam -- Adam Feuer <a...@adamfeuer.com>
