as figure show，when use stlink probe, i can't autodetect platform, there have two taps on target's scanchain, so stlink is not supported?
SoC under development, which contains two taps on daisy chain，one is normal tap, the othe is cs600-dap
I don't believe such a target is supported with ST-Link. I would recommend using a DSTREAM probe:https://developer.arm.com/Tools%20and%20Software/DSTREAM-ST#Editions
If you wish to discuss in more detail, please raise an official support case from the Support menu above.
dstream is ok, it seems stlink-v2 don't support daisy chain，
