Flashing BBAI EMMC with a USB flash drive

Hi Everyone,

I was wondering if it was possible to flash the BBAI’s EMMC using a USB flash drive, as it is using an SD card. If so, what is the process and how does it differ from the method of using an SD card? (If anyone could point me to where this is documented, that would be much appreciated!)

Thanks in advance,
Dhruv
