We designed a SAMA5D board with 32MB serial flash on SPI0, and we'd like to boot u-boot(barebox) and Linux from there. Unfortunately, at91_bootstrap ( https://github.com/linux4sam/at91bootstrap ) supports only Atmel dataflash.
I had a look at the at91sam9g20-ek bootloader package, but the project is completely different from the one in github.
I see that there's support for a "recovery flash" which is an AT25.
Has anyone started working on this so that we can share progress?
Is there any piece of advice you can give to make the development straightforward?
Thank you in advance
