Does Boot ROM have a NAND driver?

[positron]

Is the internal Boot ROM has functionality to write to the NAND?

Is the Boot ROM code opensourced, like AT91BootStrap from ATMEL?

Got it from here.

Thanks

Any links for OBDS? BTW, what it is?

Boot ROM just reads from NAND flash but doesn't write to. If you are looking for simple code for NAND read/write, OBDS is a good reference.

Not sure if it has that functionality as such, but it's main point is to read bootloader/bootstream (depending on device you have in mind) from boot device.

Code is not open-sourced, but behavior is documented in reference manual.
