We’ve got a small box of microcontroller programmers on our desktop. AVR, PIC, and ARM, or at least the STMicro version of ARM. Why? Some program faster, some debug better, some have nicer cables, and others, well, we’re just sentimental about. Don’t judge.
[Dmitry Grinberg], on the other hand, is searching for the One Ring. Or at least the One Ring for ARM microcontrollers. You see, while all ARM chips have the same core, and thus the same SWD debugging interface, they all write to flash differently. So if you do ARM development with offerings from different chip vendors, you need to have a box full of programmers or shell out for an expensive J-Link. Until now.
[Dmitry] keeps his options open by loading up the flash-specific portion of the code as a plugin, which lets the programmer figure out what chip it’s dealing with and then lookup the appropriate block size and flash memory procedures. One Ring. He also…
