I have been hunting and hunting, and have not found the TI application note project code that allows you to use a USB thumbdrive to update the firmware running on an M4 chip. I can find the USB DFU project, but that is not what I want. I have seen some forum posts reference a project called "usb_stick_update", but when i do a search on that on the TI site, I get no results other than the same few forum posts talking about it.
Has TI removed this application note and project from the site, or am I just not finding it? If someone could provide a link to it on the TI site, I would appreciate it.
