While the name might sound like a niche side project, this suite is quietly becoming the Swiss Army knife for low-cost, open-source RISC-V debugging. In this post, I’ll break down what Ejtag Tiny Tools actually is, why you need it, and how it compares to the big players. Ejtag Tiny Tools is a lightweight, open-source software suite designed to interface with EJTAG (Enhanced JTAG) compliant RISC-V cores. Originally popularized in the MIPS ecosystem, EJTAG has found a second life in the RISC-V world. These tools provide the glue logic between your host PC (Linux/Windows/Mac) and a cheap USB debug probe (like a FT232H or CMSIS-DAP).
Happy debugging!
