Hello,
I am using the Yocto “stock” image for BBB (kirkstone). During runtime, I am trying to get to the fat formatted boot partition of the image I am running on (SD card). Each time I am trying to do that I get:
root@beaglebone:~# mount /dev/mmcblk0p1 /tmp/mountpt/
[ 1196.869962] FAT-fs (mmcblk0p1): codepage cp437 not found

The fdisk output:

When I was running this Image on Dunfell, there was a /boot directory on the rootfs partition that was mapped with the boot partition. Right now, it seems its not the case, as I do not see all files there (no extlinux dir and no dtb files) + I get an additional file that is not in the boot partition (zImage-6.1.46+, its a soft link to zImage):
root@beaglebone:/boot# ls
dtb zImage zImage-6.1.46+
How to understand/ debug this behavior…? I would appreciate all help!
