I use our own ls1028 board, the emmc model is the same as ls1028ardb.
When running OpenIL-1.10 version, emmc will report the following error when starting up.

When I use the LSDK-20.12 version to test, there will be no problems when writing emmc hs400 mode.
I copied the kernel Image compiled by LSDK-20.12 and directly copied it to the image of openil-1.10 to test and there would be no problems.
I wonder if there are some problems in hs400 mode of emmc driver of rt-linux.
