Hello all,
I'm a bit confused because I'm trying since hours to connect to the STM32F105RB MCU on my board using ST-Link V2/ISOL with ST-Link utility or IAR EWB but it doesn't work. I'm always getting a "Can not connect to target" error.
It is NOT a new board I'm trying to connect to. I have programed many of them using a IAR J-Link debug probe for months now. But sadly I had destroyed the J-Link a while ago :-(!
I'm already using ST-Link V2/ISOL adaptors for an other board with the same STM32F105RB MCU and an identical debug layout (jtag) and debug & programming works without problems.
I've updated the ST-Link FW to the newest version, tried it with different USB and probe cables, with different boards, with both ST-Links I have, different software settings - but nothing really works...
My cable setup is:
ST-Link Pin MCU

01 VAPP VDD
03 TRST JNRST
05 TDI PA15, JTDI
07 TMS_SWDIO PA13, JTMS
09 TCK_SWCLK PA14, JTCK
13 TDO_SWO PB3, JTDO
15 NRST NRST
20 GND GND
Does any one have an idea what I'm doing wrong?
Any help & hints are very welcome!
Thanks,
Roger
