QNX on Raspberry Pi - Unable to mount SD card partition

Thanks for your replies @Tim @nico04 .

I did try formatting the SD card to FAT32 under Windows but after booting to QNX, I did not see any partitions in the partition table.

# df -h -P

I get the same problem even when I create more than one FAT32 partition in Windows. The partition table for the SD card in QNX still contains no entries. If I transfer the SD card back to the Windows host, I’m able to see the formatted FAT32 partition(s) again. Am I missing something here?

It should also be noted that I’m copying the BSP and required firmware files to the FAT32 partition on the SD card and booting QNX from there. Can this possibly affect the FAT32 partition on the filesystem after booting into QNX?
