How LS1043A boot from emmc?

Hahawell — Wed, 12 May 2021 06:21:24 GMT

Hi,expert!

Our Linux system boots from SD card now, We hope that it boot the system from the EMMC on the PCB board,and SD Card and EMMC use the same SDHC interface.

We don't find any informations about the operations.

Otherwise,the debug uart intreface and the ethernet interface work well,and there is a QSPI flash on the PCB board.

I hope someone can give us some advise.

Thanks.

It is impossible to simultaneously use SD card and eMMC.
