Hi FreeBSD USB peeps,
I recently bought myself a small bluetooth development board to tinker with - a
SparkFun Pro nRF52840 Mini:
https://www.sparkfun.com/products/15025
But I am having difficulty mounting the mass storage device it presents when in
bootloader mode (accessible by double tapping the reset button). In this mode
it presents 3 devices at once - a USB serial (CDC), a DFU (device firmware
upgrade) and a mass-storage device (MSD).
When I attempt to mount the FAT32 formatted mass storage device I get the error:
mount_msdosfs: /dev/da1: Invalid argument
I suspect the issue is a USB quirk, and I may just need to use usbconfig with
the right command to fix it. I'm hoping someone is able to help me get this
mounting, or troubleshoot further?
Cheers,
Ben

Try to clean the volume with fsck_msdosfs first.
