I am using buildroot on at91rm9200 based platform with NOR flash. It's
not latest buildroot, but the one published by Ulf Samuelson in 2006.

Subject: [Buildroot] ATMEL SAM9 board
Hi all,
I have a prototype board based on AT91RM9200+AT45DB64.
I have evaluated the buildroot framework starting from the at91rm9200df
configurations set that is tailored on the AT91RM9200-EK. Changes were
made since my board has a different ethernet PHY and a different GPIO
map, to leds, MMC/SD, etc..
The most important difference with respect the at91rm9200df
configurations set is that I need the linux kernel mounts the root fs
read-write on the dataflash.
I have changed the u-boot bootcmd and bootargs accordingly (defenv) and
the linux kernel .config in order to use only the legacy AT91RM9200 SPI
driver (the only SPI driver that detects the dataflash).
U-boot and linux work fine but I still have problems with the file
system image. It seems that the kernel doesn't find initrc (busybox),
there are not scripts outputs to console.
I suppose the problems can be solved (hints will be appreciated) but I
have to decide between keeping the AT91RM9200 board as production board
or to design a new board based on another ATMEL SAM9.
My question is: in your opinion/experience how good buildroot supports
ATMEL SAM9 + Dataflash or ATMEL SAM9 + NOR Flash platforms?
Thank you,
Mike.
