The sdhc_cmd_r1_raw() function doesn't take into account the existence of commands with data response. Because of this, some datas were being lost. The commands that return a r1 response and a data are: SDHC_SEND_CSD, SDHC_SEND_CID, SDHC_READ_SINGLE_BLOCK, SDHC_READ_MULTIPLE_BLOCK, SDHC_WRITE_BLOCK, SDHC_WRITE_MULTIPLE_BLOCK. In order to solve this, was juts necessary skip the byte discard when the command is one of these. This problem was affecting, for example, the sdhc initialization. The token returned from SDHC_SEND_CSD was being lost and the initialization was broken. Fixes zephyrproject-rtos#15444. Signed-off-by: Lucas Peixoto <[email protected]> Signed-off-by: Peter A.

Backport on #17700 failed, hopefully this is the right recovery process for non-maintainers. |

SDHC_WRITE_BLOCK, SDHC_WRITE_MULTIPLE_BLOCK.
