Interesting development. I was looking at the pin out on the tweet to see whether it use JTAG or SWD. All I can find is USB, so no guidance there. Either signals can be routed through USB I believe. I know JTAG can, but my limited knowledge means I am not sure about SWD.

For me the Cortex-M33 is in the same chip with the WiFi/BT, while Risc-V and the other digital functions are in another chip. Anyway, some hybrid is popping out. ________________________________ [tickets:#378]<https://sourceforge.net/p/openocd/tickets/378/> SWD support for RISCV artchitecture Status: new Milestone: 0.10.0 Labels: openocd Created: Wed Dec 28, 2022 07:00 AM UTC by Ashi Gupta Last Updated: Sat Jan 07, 2023 11:34 AM UTC Owner: nobody Hi, I want to know if SWD debug support has been added for RISCV architecture in openocd ? So far i know that JTAG support is only available. If not any plans in doing so ? ________________________________ Sent from sourceforge.net because openocd-devel@lists.sourceforge.net<mailto: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.
