JLink JTAG Access on the Pinecil
The article discusses the use of JLink JTAG access with the Pinecil soldering iron. It highlights the importance of debug access for troubleshooting system initialization and driver issues. The author provides detailed instructions on connecting the JLink to the Pinecil breakout board for effective debugging.
- ▪The Pinecil soldering iron has gained upstream support for the Bouffalo Lab BL706 MCU in Zephyr.
- ▪A breakout board is required to connect a JLink to the Pinecil, featuring a 10-pin header for JTAG breakout.
- ▪JLinkExe can be used to verify the correct mapping of pins after connection.

JLink JTAG Access on the Pinecil May 30, 2026 4-minute read It has been more than two years since I bought a Pinecil soldering iron and wrote about soldering the breakout board and accessing the UART. I’ve been doing more work with the Pinecil as of late following the addition of upstream support for the Bouffalo Lab BL706 MCU in Zephyr (big shout out to @VynDragon, @will-tm, @josuah, and everyone else who has been contributing to the upstream Bouffalo Lab efforts!). While accessing the UART is helpful for viewing logs, debug access is critical when chasing down early system initialization and driver issues. While there are a variety of JTAG probes on the market, I typically reach for my JLink due to its broad compatibilty and robust tooling.
