AM2432: GPMC 32-bit Data

MCU-PLUS-SDK-AM243X: GPMC driver supporting Non-mux 32bit Data bus and 23bit Address

Part Number: MCU-PLUS-SDK-AM243X
Other Parts Discussed in Thread: SYSCONFIG

Hi,

Mari asked on another thread below. 

https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1158748/am2432-gpmc-32-bit-data/4364328#4364328

In this thread, we received the following comment.

>  Since GPMC is not currently supported in the MCU+ SDK, the SysConfig does not support GPMC.

Do you have a plan to release GPMC driver supporting Non-mux 32bit Data and 23bit Address ? If you have, could you tell us the schedule ?

Also, why there is no description and the GPMC use case of Non-mux 32bit data in the data manual or TRM ?

Regards ,

Hideaki

    HI Hideaki-san,

    The GPMC PSRAM driver for MCU+ SDK will be released in 08.06.00 on 3/30/2023

    GPMC NAND driver for MCU+ SDK will be released in 09.01.00 on 11/30/2023

    GPMC FPGA driver for MCU+ SDK will be released in 09.02.00 on 3/28/2024

     We will update the datasheet and TRM for the 32-bit data support in non-multiplexed mode.

    Best regards,

    Ming
