Error: openOCD 0.3.1

Development Boards MicroMod

Hello,

We are using openOCD 0.3.1 with the Raisonance dongle and STM32F107vct6 board. Earlier everything was okay. It was working fine. But Now I am getting this error after issuing the command

openocd.exe -f interface/rlink.cgf -f board/stm32f10x_128k_eval.cfg

Error: JTAG scan chain interrogation failed: all ones

Error: Check JTAG interface, timings, target power, etc.

Regards,

Paul

I’d suggest trying the latest version of OpenOCD that you can find here: http://openocd.sourceforge.net/getting-openocd/

0.3.1 is a really old version, even though it’s still included with most Linux distributions. You’ll get more help with the newer version.
