Hi Salman,

S80KS2564GACHV043 is not supported by GPMC.
Please refer to section 12.3.3.4.10 GPMC pSRAM Access Specificities in AM243-TRM to see the compatible interface protocol for PSRAM-GPMC

Also, refer to this E2E thread (+) AM2432: pSRAM for AM243x - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forums

Thanks & Regards,

Hi Salman,

Sorry for the delay in responding.

The PSRAM which we have validated for GPMC is IS67WVE4M16EBLL (8MB).
GPMC can support any PSRAM with similar signals as in the above mentioned PSRAM.

Thanks & Regards,
Rijohn
