no mmcblk* devices on system, even with SD card mounted
jelabarre59 opened this issue · comments
On Fedora 33, the microSD card is mounting the device from /dev/sde# to /run/media/user/boot, but no block device shows at /dev/mmcblk* . I'm presuming the newer version of Fedora is using a different location now, and won't show the path you are looking for.
Most likely your system is using an SD-bridge that exposes the card as a mass storage device over USB, these can't be used with this code. You need a native interface.
