Boot from USB memory stick?

Post by ke4th »

I'd like to boot my Pi-Star hotspot from a USB memory stick. The Pi is an early model 3 with a DVMEGA rf board. From what I've found on the internet, if I can access the boot file, I can add a line that will enable USB booting. I'm running version 4.1.5 of Pi-Star. Thanks for any guidance!

R-Pi boot files are located in the FAT partition of the SD card. Even Windows can read/write to that partition.

Code: Select all

C:\Users\Wulfraed>dir K:\
 Volume in drive K is boot
 Volume Serial Number is 4792-8B04

 Directory of K:\
