FYI to all:for new (old stock) devices failing flashing.

[aloeppert]

Hi all,
I recently added a new greatfet to the menagerie (bought one several years ago). There was a little confusion bringing the new device up-to-date. Having no build problems for the latest firmware and putting the device in DFU mode, I needed to first put the new firmware in RAM before updating the ROM

So:
(venv) loeppert@adl:/usb-hid/greatfet/firmware/greatfet_usb/build$ make greatfet_usb-flash
failed
but:
(venv) loeppert@adl:/usb-hid/greatfet/firmware/greatfet_usb/build$ make greatfet_usb-program
(venv) loeppert@adl:~/usb-hid/greatfet/firmware/greatfet_usb/build$ make greatfet_usb-flash

This updated as expected. I didn't see any such mention in the docs - which obviously I could update (but maybe I missed) as this is an open source project, but I wonder if others are having the same issue.

(venv) loeppert@adl:~/usb-hid/greatfet/firmware/greatfet_usb/build$ gf info
Found a GreatFET One!
Board ID: 0
Firmware version: git-v2021.2.1-64-g2409575
...

I'm using "Ubuntu 23.04", with a virtual env. for python 3.11

The error message for trying to flash without programming first is (again, the board is in DFU mode verified by lsusb)

Putting this out there to save someone some time in-case they have the same issue as me and the search engine finds this.
