Any way to mount SDCard from serial? (working with partially borked device)

I've got a couple v2 cams that are borked. They partially boot, but then hang. I think the boot loader is messed up. I wanted to try just re-flashing the bootloader from a serial console connection I have (via unpopulated serial header) using these commands.

The problem is that the cams don't boot enough into an environment that has the typical SD card mappings, and don't know what device is the SD card.

Can anyone suggest where to get the SDcard so I can mount it?

I can access the root file system, but don't know where the SD card is located to mount it:
