SK-TDA4VM: MMCSD driver to communicate with eMMC is not working

SuryaPrakash Durairaj

Part Number: SK-TDA4VM

Hi,

I am running fatfs console test example to communicate with eMMC on SK-TDA4VM board using processor SDK RTOS version 08_06, when I run the code, eMMC initialization is getting failed.

The above piece of code is in  MMCSD_v2_initEmmc function of file MMCSD_v2.c, when this command is transferred, I am getting COMMAND EXECUTION FAILED error in the MMCSD_v2_transfer function.

There is no code change I am just running the example code in SDK and it is not running. Please support me to resolve this issue.

    Hi Surya,

    The SK-TDA4VM does not have an onboard eMMC, since the SK boards remove many peripherals and onboard devices to cut down on cost.  eMMC examples would not work on the SK board due to this hardware limitation.

    For evaluating our eMMC examples and other PSDK RTOS examples, the recommendation would be to buy the J721E EVM board which has the same SoC as the SK-TDA4VM board, but has more of the peripherals and devices including the eMMC pinned out: https://www.ti.com/tool/J721EXSOMXEVM
