Should not be a problem when using SD card.

DennisDNguy commented 1 year ago

I'm using SD card, but I afraid that the image won't run probably. Does anyone know how to increase the 4 MBytes limitation?

Spudz76 commented 1 year ago

It's not limiting, it's warning you. Since you know it's not an issue for SD simply ignore it.

I did not locate anywhere in at91 where IMAGE_SIZE gets set which is probably the issue, then I guess it defaults to the worst possible size, 4M. During SD build it should be setting it to 64M as that is the size it uses for a boot-partition.
