When using cmsis-dap + jtag + riscv, probe-rs reports `The selected probe does not support the 'RISC-V' interface.`

What probe are you trying to use? This error sounds like the probe itself does not report JTAG compatibility.

I'm using my cmsis-dap which supports jtag. openocd works well, but probe-rs doesn't recognize this combination（cmsis-dap+jtag+riscv）

[bugadani]

But which cmsis-dap? What is the exact model?

[bugadani]

Okay nevermind, looks like JTAGAccess needs to be implemented for cmsis_dap, and also the try_get_XX functions at least.

[HaoboGu]

Okay! To make it work, JTAGAccess and try_get_riscv need to be implemented, am i right?

[bugadani]

Yes (well there are two functions, has_riscv_interface and try_get_riscv_interface_builder) and if you'd do that I'd ask you to add the xtensa bits as well, it should be fairly easy once JTAGAccess is implemented.

For the RISC-V builder stuff you can see examples in the other probe impls.

thanks for the guidance, I'll have a try!
