Sometime my uSD card cant be mounted because the port never booted. The only method i currently have is the reboot.
this is recurent and I don't have any solution to reboot with linux command the port to get sda1 or sdb1 in /dev/ ... and mount to /mnt/sda1 my SD card.
Do you have a linux command to reset or reload, or what ever but no reboot the mcu to get my uSD port visible. thank you

I can confirm existence of multiple SDA1 errors that force the OS to set the partition to read-only. The file utility BLOCK has already tried to correct the errors by calling /usr.sbin/dosfsck, but dosfsck is not enabled or install-able in Openwrt.

When set to read-only, the sketches are blocked from writing data to the partition and this renders my system testing useless. From what I can glean from openwrt forums, fsck.fat should be enabled and utilized instead.
The issue has been mentioned and a correction posted but I have no idea how to compile the firmware.
