Hi there,
"mcurtis@MCURTIS-VHRYWFGF0V ~ % screen /dev/cu.usbserial* 9600

Then, here's what I get after I try to boot from a USB:
"rommon 15 > dir usbflash1:
program load complete, entry point: 0x80903000, size: 0x4c4a0
fnuhcd5200OpenPipe ERROR opening PIpe CVMX
*** TLB (Load/Fetch) Exception ***

Cause Reg = 0x80000008, Status Reg = 0x504080e3
monitor: command "dir" aborted due to exception"
How do I get past this?
Thanks!

Hi
When you ran dir usbflash1: you should be able to see what is in there. Make sure the USB has the right format and it seems it is not recommended to use USB driver bigger than 2Giga.

Is there a specific flashdrive you recommend? I was looking at this one: https://www.amazon.com/Flash-EASTBULL-Swivel-Memory-Storage/dp/B07W54X2F3/ref=sr_1_9?crid=36MH8MUJIW4PR&keywords=1gb+flash+drive&qid=1685722782&sprefix=1gb+flash+drive%2Caps%2C67&sr=8-9

The USB is a 32GB SanDisk in FAT format. I will try again with another flashdrive.
