Nucleo F401RE

[surly]

Hello,
I'm trying to debug the ARMCM4-STM32F401RE-NUCLEO demo but when I launch OpenOCD on ST-Link V2 with st_nucleo_f401re.cfg
I get this :

Open On-Chip Debugger 0.8.0 (2014-04-28-08:39)
Licensed under GNU GPL v2
For bug reports, read

srst_only separate srst_nogate srst_open_drain connect_deassert_srst
Info : This adapter doesn't support configurable speed
Error: open failed

Please anyone can help me ?

Thank you!

Hi,

Are the stlink2-1 drivers installed?

Oh I think the problem was with the previous installed ST Virtual Port driver,
I removed the ST Link Device and reinstalled the driver,
now it works because it takes the right driver.

Thank you!!!
