AM437X GPMC address map

Hi,

We have two GPMC chip selects interfaced with NOR protocol memory where we are facing issue in accessing these memory.

Below is the GPMC base addres and size configuration I am using,

CS1 - GPMC_CONFIG7_1[5-0]=0x1
GPMC_CONFIG7_1[11-8]=0xF

CS2 - GPMC_CONFIG7_2[5-0]=0x2
GPMC_CONFIG7_2[11-8]=0xF

1)In my understanding, we should use chip select base address starting from 0x01000000(CS1 base address). Am I correct here?
2)In case of CS2 I have set size to 16MB, is it possible to increase the size to 32 or 64MB with the same base address(0x2000000)?


Thanks,
Vishakh
