I am running into strange problems with the built-in emmc card in my FriendlyElec nanopc-t6. OpenWrt seems unable to read/write it. If I flash Openwrt 24.10.1 to the emmc, it tries to boot but ends in kernel panic. If I boot OpenWrt from the SD card, it boots OK, but runs into difficulties accessing emmc and throws errors along the lines of:

I would suspect faulty emmc, but...
If I boot FriendlyWrt from SD - it has no problem reading/writing to emmc. The same goes for booting Armbian - no issues with emmc. The problem appears to be OpenWrt-specific. Any suggestions how to proceed?
