Since the JTAG pins from the wireless module are broken out on the bottom of the Photon RedBoard, is it possible to replace the Particle firmware with my own firmware? I’m hoping to use this board as a way to prototype something with the WICED SDK and if it’s possible to reprogram the STM on the WiFi module via JTAG/SWD then I think it’ll work for my project.
Hi Evan.
It probably is possible, but that’s not anything we’ve ever attempted to do before. Unfortunately we’re not able to assist with. The [JTAG and SWD section of the datasheet might be helpful for this.](https://docs.particle.io/datasheets/wi-fi/p1-datasheet/#jtag-and-swd)
