You could add that to the > commit message. Hi Adrian, Thanks for the review! Yes, I've seen an issue on STM32MP157C-EV1 board. After a write test (e.g. test 36), the tests 37 or 38, using mmc_erase fail. With the erase argument used by default in the framework (MMC_DISCARD_ARG), I can no more see this. I can send a new version of the series with comment update here, and a fixup on the first patch.
