RISC-V External Debug Support Version 0.13 3 Accessing hardware on the system without a working CPU. Accessing custom registers that could be added to aid in hardware debug, system bringup, etc. Writing code and data to memory, e.g. boot code and manufacturing constants. Analyzing low-level performance issues using pro ling and sampling techniques.
RISC-V External Debug Support | Five EmbedDev 5 RISC-V Debug Modifications to the RISC-V core to support debug are kept to a minimum. There is a special execution mode (Debug Mode) and a.
