You can also enable following options: CONFIG_MMC_IO_VOLTAGE=y CONFIG_MMC_UHS_SUPPORT=y CONFIG_MMC_HS400_ES_SUPPORT=y CONFIG_MMC_HS400_SUPPORT=y For HS400_ES mode also needs to add `mmc-hs400-enhanced-strobe` line to the emmc node in the Lichee's DT. HS200/HS400/HS400_ES modes work fine with eMMC on my Lichee Pi4A board. MicroSD works fine at UHS SDR104 too. Bus Speed for both devices is 198MHz > I tested reading from eMMC and SD-card as well as writing to SD-card and > found no problems. > > Tested-by: Heinrich Schuchardt <heinrich.schucha...@canonical.com> Thanks for testing!
