After building the MMDVM shield by Toufik F0DEI I tried to flash the MMDVM firmware using the MMDVM Makefile and executed “make deploy”. That command failed and the output said something about that it could not open the port. After looking through the openocd config files I discovered that it looks for a device with 0x0483/0x3748 as VID/PID.
But in my case the board showed up with 0x0483 0x374b. After changing this in /usr/share/openocd/scripts/interface/stlink-v2.cfg the deploy command worked like a charm and transferred the firmware successfully. By the way: This was done on an Ubuntu 16.04 with openocd v0.9.0 installed from the official repositories.
