Hi,

So, I quickly built the bootstrap for A9263 and it was ~71KB in size.
This is OK for the A9263 with 96KB of SRAM, but the A9G20 only has
2x16KB. So, I think I'll need to update at91bootstrap to unbrick my
device. at91bootstrap is ~4-5KB from what I observed. But thanks for the
inspirtation!

Happy hacking,
