PROCESSOR-SDK-DRA8X-TDA4X: MCU1_0 cannot be successfully started with EMMC boot mode

Part Number: PROCESSOR-SDK-DRA8X-TDA4X

Hi 

I am using custom board with 7.1 Linux SDK and the board is using EMMC-BOOT mode.

The board is designed with OSPI Flash and EMMC.It doesn't have SD card.

After searching and querying, it is found that there is an open issue with the OSPI boot in SDK7.1.I hope TI can solve it as soon as possible!

-------------------------------------------------------------------------

Therefore we have to use EMMC to boot our board.After my test on our board, I found that whether I boot my board with EMMC-BOOT boot mode or EMMC-USER boot mode,the MCU1_0 cannot be successfully started runinging /opt/vision_apps/vision_apps_init.sh without any log from MCU1_0 .

After I switched to DFU and started, I found that everything was normal.I could see MCU1_0 printed message using /opt/vision_apps/vision_apps_init.sh

-------------------------------------------------------------------------

I thought it was my board problem, But I tested it on EVM board and found it was the same result with EMMC-BOOT boot mode or EMMC-USER boot mode

After I switched to DFU or SD boot mode, I could also see MCU1_0 printed message using /opt/vision_apps/vision_apps_init.sh

--------------------------------------------------------------------------------------------

Could you please help me analysis the qustion?Is this a known problem or do we need to change the code?
