Hi,

i am using NucleoF401 and chibi studio. I got error while opening configuration using openOCD.

i took stm32f4discover.cfg file. and i got following error.

Code: Select all

Is it problem with board or configuration file.

Hi,

Does it work with other boards or other STM32s?

for other board i select other configuration file and it is working. like stm32f103 and stm32f303xx.

but for NucleoF401RE only i m facing problem. I tried other board too, but same problem.

Might be issue with configuration file.

Try selecting target/stm32f4x_stlink.cfg

Hi,

i tried stm32f429discovery.cfg, not working. but stm32f429disc1.cfg is working.

Is it ok, if i m using stm32f401xx processor and config file is different?

If it is able to flash it then it is OK.
