I'm working in a vagrant virtualbox, trying to flash my beaglebone. The device is passed through using virtualbox usb filtering.

I'm not sure how to compile the usb_flasher application for debugging.

So I commented out line 217 in main.c, and it made it further (It's currently apparently sitting doing something(?) after printing "SPL has started!" It appears to be using 100% CPU too.

Sure, it now leaks the device list, but I don't really care as long as it works?

Hi @fake-name , I've made a node.js bootloader server for BeagleBone here . Well, almost a port of BBBlfs but with some changes. It can boot BB into USB mass storage utilising uboot's ums feature. Please try it, and provide feedback. I'm working on a complete GUI flashing tool also.
