SD card bootloader - convert assembler to C++? in Energia - MSP Posted April 16 Thanks very much for your replies. I'll go back and study what you've said, but it kinda looks like it just needs to stay in Naken assembler. That produces a .hex file which I flash to the chip with TI's MSP Flasher. There is no "environment". And I think any attempt to convert it to C is just bound to make it larger and less efficient.
