Actually, I'm not sure about the sam9rl. The previous code was doing: switch (at91_soc_initdata.cidr & AT91_CIDR_SRAMSIZ) { case AT91_CIDR_SRAMSIZ_32K: sram_size = 2 * SZ_16K; break; case AT91_CIDR_SRAMSIZ_16K: default: sram_size = SZ_16K; }
So the SRAM size should be 16k or 32k but what I get from the only cidr registered for sam9rl (0x019b03a0, also from the datasheet) is SRAMSIZ= 0xb which give 64k. Could you confirm?
