In mmc_blk_cmd_recovery(), re-tuning would fail before sending CMD13 on our specific board. This may be some issue related to specific eMMC card we are investigating. The above is just background introduction, and you may not care about that:) I'd like to have some queries on CMD12 usage in MMC driver. 1.If you search for "stuff bits" or > "CMD13" in the spec, you will get the information. > > > > > The SPI responses are not well implemented, in this case (CMD13) > > it is incorrect, we should return a 2-byte R2.

The SDIO controller can send CMD13 during card programming mode to check the card status. If software sends an R1b response type command (e.g., CMD38, CMD6) followed by a CMD13 (status check), the controller sends the transfer complete before completing busy due to the CMD13 status check. This can be avoided by not sending a CMD13 immediately ...

At any time, you can determine the state of the card's password lock by sending a CMD13 (SEND_STATUS) and examining the two-byte response, which is the card status. I found the spec to be very confusing regarding this register and the response to a CMD13. The goal is to read the LOCK/UNLOCK bit, which is bit 8 of the 16 bits …
