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?
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,
Does ST-LINK Utility support multiple devices on J... - STMicroelectronics Community
