Hello, I obviously had both problems. I needed to set the vid/pid in the config file plus the permission problem. I fixed this and got one step further. But it is still not working. Openocd is obviously talking to the ft2232 chip but still not to the ST32-PerformanceStick.
My openocd.cfg: source [find target/stm32stick.cfg] # ftdi interface interface ft2232 ft2232_device_desc "STM32-PerformanceStick A" ft2232_layout stm32stick ft2232_vid_pid 0x0640 0x002d gdb_port 4789 and I get the following Open On-Chip Debugger 1.0 (2009-03-09-14:42) svn:1405 BUGS?
