J-Link RISC-V

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
