I suspect that my settings in device tree are not right, specifically the dma configuration. But I couldn't figure out what would be the correct settings.

2. I got a Beelink BT3-X. Same manufacturer, exact same problem. I "solved" it by disabling SD card altogether in the BIOS. Navigate to Chipset -> SCC Configuration and disable SCC eMMC Support (D28:F0). This however just means that I'm unable to use the SD slot. Yeah... fortunatley I don't plan to use the slot. Share.

In sdhci_finish_data (), as my patch changes, I think for data->error, the CMD12 should be sent. 2. In mmc_blk_mq_rw_recovery () in block.c, CMD13 will be sent with one more retry (retuning may happen), before CMD12. 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 ... CMD13 - Addressed card sends its status register. This function waits the clear of the busy flag. Returns true if success, otherwise false .
