The following settings were made to save the u-boot env to eMMC.
U-Boot 2022.01
CONFIG_ENV_IS_IN_MMC=y
CONFIG_SYS_MMC_ENV_DEV=0
CONFIG_SYS_MMC_ENV_PART=0
The write operation succeeds once, but then the eMMC stops responding.
Writing by ums is also successful, so writing itself seems to be OK, but there seems to be a problem in the subsequent operation.
What are the problems with writing to eMMC?
