Hi Roger, >> >> For now, I'll use GPMC address-space size = 0x380 as it matches with >> actual hardware and is working. > >How did you get 0x380? > >From DRA7 TRM, GPMC address range is 0x5000 0000 : 0x5000 02D0 >So the address-space size should be 0x2D4 (as last register@2D0 is 32-bits wide) > I think that is copy-paste error in documentation. In the same TRM, you 'll find the correct address offsets for GPMC Registers in below *Section: 15.4.7.1 GPMC Register Summary* Register Starting Offset End Offset GPMC_BCH_RESULT4_i 0x0000 0300 + (0x0000 0010 * i) 0x5000 0300 + (0x0000 0010 * i) GPMC_BCH_RESULT5_i 0x0000 0304 + (0x0000 0010 * i) 0x5000 0304 + (0x0000 0010 * i) GPMC_BCH_RESULT6_i 0x0000 0308 + (0x0000 0010 * i) 0x5000 0308 + (0x0000 0010 * i) Where i = 0 to 7 .. So that makes last address 0x5000_0378 (for GPMC_BCH_RESULT6_7) As the each register bank (i) is incrementing at 0x10, so last accessible address is 0x37F. I have already raised documentation bug for AM335x TRM, Need to raise the same for DRA7xx TRM. >For the ELM module it should be 4KB i.e. 0x1000 > Yes, that is correct.
