Tool/software: Linux
Hello，
I want to use the Linux to my own board card, which is started by emmc，and the processor is TDA2SX
Due to different hardware, I have modified the DTS file, attached is the DTS file I modified, and the log.txt file is the printed debugging information of kernel startup, which shows that emmc cannot be mounted.
