facing problem with openOCD for F401RE

[ep.hobbyiest]

I am using Nucleo401RE and chibi studio.
My OS version is Windows 10 - 64bit.
open ocd is giving following error.

Code: Select all

I tried all .cfg file related to stm32f4xxx.cfg but not working.
Is this problem with chibi studio or open ocd or something else.

Hi,

There are similar reports from other W10 users: viewtopic.php?f=13&t=3655

I don't have W10 but I know for sure OpenOCD should work, others used it.

Hello, Can I Know Which openOCD you used to solve the problem? I tried with all available openOCD but I have not solved

[ep.hobbyiest]

I have downloaded the open OCD from following linkhttp://www.chibios.com/forum/viewto ... =13&t=3457

Hi,
this is the latest version of OpenOCD I have built
http://www.playembedded.org/blog/wp-content/uploads/2016/07/openocd.zip
can you give us a feedback after using it?

I tried the openocd provided by RoccoMarco but the problem persists while the link provided by ep.hobbyiest leads me to a blank page. However my problem might be different even though the message shown by Chibistudio is the same, because I can not connect even by ST-Link tool. My problem is described in more detail in this topic viewtopic.php?f=13&t=3655 . Thanks for support.

As said here, try to make a full chip erase with ST Link Utility.
