Hello, is the mmc tool from mmc-utils supposed to work with SD cards? I tried mmc status get /dev/mmcblkN with three different SD cards on two different machines (Pinebook Pro and a Sony laptop) and I get the same error on both: # mmc status get /dev/mmcblk0 ioctl: Connection timed out Could not read response to SEND_STATUS from /dev/mmcblk0 dmesg on the Sony machine shows: [ 1291.196547] mmc0: new SD card at address aaaa [ 1291.196834] mmcblk0: mmc0:aaaa SD01G 969 MiB [ 1291.200263] mmcblk0: p1 p2 p3 [ 1306.273160] rtsx_pci_sdmmc rtsx_pci_sdmmc.0: __mmc_blk_ioctl_cmd: cmd error -110 [ 1306.276978] mmcblk0: p1 p2 p3 I'm able to get status of the internal eMMC device on Pinebook Pro with no errors. extcsd read works fine, too. I'm running Fedora 38 with kernel 6.2.9 on both machines if that helps. Regards, Dominik -- Fedora https://getfedora.org | RPM Fusion http://rpmfusion.org There should be a science of discontent.
