cc3200tool, https://github.com/ALLTERCO/cc3200tool is a (mostly, some binary blobs present) open-source, Linux-friendly tool to flash a cc3200 devices. It's an alternative to fully proprietary, Windows-only Uniflash from TI. The provided make targets are for erasing flash, flashing the uPy bootloader and firmware, and flashing vendor's WiFi firmware "servicepacks" (the latter needs to be downloaded from vendor side, a link is present inside Makefile).
