The git version "fdf17dba5" is not in the history of upstream OpenOCD. Should be some MacOsx build... anyway, not a problem so far!

OpenOCD looks for a valid USB interface which descriptor starts with "CMSIS-DAP". Here it seams using the "CMSIS-DAP DCI" which is probably incorrect. Can you post the complete output of "lsusb -v -d c251:f001"? It will help identify the right interface number and will be kept as another reference dump for cmsis-dap devices. Then, adding in your configuration the command "cmsis_dap_usb interface <num>" should work. It could also help creating a dedicated config file for this interface! --- ** [tickets:#327] can't connect cmsis-dap v2 device. ** **Status:** new **Milestone:** 0.11.0 **Created:** Mon Dec 20, 2021 09:29 AM UTC by Qinfeng Chen **Last Updated:** Mon Dec 20, 2021 09:29 AM UTC **Owner:** OpenOCD-Gerrit **Attachments:** - [log.txt](https://sourceforge.net/p/openocd/tickets/327/attachment/log.txt) (8.8 kB; text/plain) Version: Open On-Chip Debugger 0.11.0+dev-00542-gfdf17dba5 (2021-12-17-19:05) Env: MacOsx 11.6 intel version. description: can't connect cmsis-dap v2 device. detail: see the trace log below. --- Sent from sourceforge.net because openocd-devel@lists.sourceforge.net is subscribed to https://sourceforge.net/p/openocd/tickets/ To unsubscribe from further messages, a project admin can change settings at https://sourceforge.net/p/openocd/admin/tickets/options.
