Unknown Chip ID 0xe0042000 #451
Description
How can I help to fix "stlink/src/common.c: unknown chip id! 0xe0042000" ?
- Programmer/board type: e.g Stlink/v1, Stlink/v2, Stlink/v2-onboard
ST-LINK / V2
B 2015 30
This looks like a normal standard Stlink/v2, as far as I can see from the various pictures on the internet.
- Programmer firmware version: e.g STSW-LINK007 2.27.15
Unknown. Perhaps the lsusb output is useful?
$ lsusb -v

Expected/description:
I'd hoped the chip ID would be supported :-)
