This article handles J-Link related RISC-V specifics. It is assumed that RISC-V as a term is already known. For more generic information about RISC-V, please refer to the RISC-V knowledge base article

Watchpoint support
J-Link supports data breakpoints (watchpoints) for RISC-V CPUs which are based on the V0.13 standard of the RISC-V debug spec. In general, the following combinations are possible for a watchpoint:
- Addr == EXACT, Data == EXACT
- Addr == EXACT, Data == ANY
- Addr == EXACT, Data == RANGE
- Addr == RANGE, Data == EXACT
- Addr == RANGE, Data == ANY
- Addr == RANGE, Data == RANGE
- Addr == ANY, Data == EXACT
- Addr == ANY, Data == ANY
- Addr == ANY, Data == RANGE
Note: Right now, only the ones shown in bold are supported by J-Link
