target/riscv: always validate dmstatus.version field#21
Merged
Conversation
Based On: https://review.openocd.org/c/openocd/+/9460 The dmstatus.version field indicates which revision of the RISC-V debug specification the debug module implements. Since this field is always readable, validating it on every dmstatus access provides a simple and effective check that JTAG communication with the target is functioning correctly.
