Hello, can you please tell me what the maximum total asynchronous memory size is the GMC can address is? I read 128MB - is that for each CS signal?

Thanks

    Hi,

    The GPMC total address range is 512MB, from 0x00000000 to 0x1FFFFFFF, with the restriction that the first 1MB of address space from 0x00000000 to0x000FFFFF is inaccessible externally. This address range can be distributed between the 7 available chip-selects in chunks of 16, 32, 64, 128 or 256MB.
