5 # Test U-Boot's "mmc write" command. The test generates random data, writes it
6 # to the eMMC or SD card, then reads it back and performs a comparison.
12 This test relies on boardenv_* to containing configuration values to define
13 which MMC devices should be tested. For example:
15 env__mmc_wr_configs = (
17 "fixture_id": "emmc-boot0",

26 "fixture_id": "emmc-boot1",
