Hi team,
Here's an issue from the customer may need your help:
SDK version: 08_02_00_03（ti-processor-sdk-linux-j7-evm-08_02_00_03-Linux-x86-Install.bin）
Porting this part to the custom board and start it with an SD card, but failed. After changing the main_sdhci1 node in device tree it can start normally and the reason why it failed is that the custom board mmc H/W portion of the power supply is different with the EVM.
Once started, the customer checked the eMMC related information and found that the eMMC was not recognized at all. And then in the uboot phase, enter into the uboot command line and look at it with the mmcinfo command, it reports as follows:
=> mmcinfo
Card did not respond to voltage select! : -110
mmc_init: -95, time 45
=>
While eMMC can be properly recognized when plugging into the EVM board with the same card.
Issue: how to make the 08_02_00_03 version of the SDK support SanDisk's eMMC without changing the hardware?
Could you help check this case? Thanks.
Best Regards,
Cherry
