TDA4VM: TDA4VM: Card did not respond to voltage select for mmc0

Dear SIr:

Our software uses Linux RT SDK 08_00_00_08 and the hardware design uses SD card and EMMC

Currently we can boot from an SD card and met an issue that mmc0(emmc) cannot be detect on custom evm board in uboot and linux.

And we always got "Card did not respond to voltage select".

We try to use ""mmc rescan" in uboot, but still the same.

Is there any setting need to fine tune?

=> mmc rescan
Card did not respond to voltage select! : -110
mmc_init: -95, time 168
=> mmc list
sdhci@4f80000: 0
sdhci@4fb0000: 1
=> mmc dev 0
Card did not respond to voltage select! : -110
mmc_init: -95, time 181

请问是否有参考过下面的帖子？emmc硬件接法是否和EVM板一样？https://e2e.ti.com/support/processors-group/processors/f/processors-forum/851042/tda4m-card-did-not-respond-to-voltage-select-error
