[ANSWERED/SOLVED]J-Link JTAG Isolator and SWD

Does the JTAG Isolator work with devices on the SWD chain?

I recently purchased a JTAG Isolator for use with an STM32F100 Cortex M3. Without the isolator everything works, with the isolator I get a wrong AHB ID error.



Thanks

Hi,

the JTAG isolator is for JTAG only. It is not designed for bi-directional pin usage (as it is the case for SWD).


Best regards
