True, but if you issue that command from a REPL over USB then it has the downside of clobbering the terminal program by eliminating the tty device it is connected to. Not a catastrophe usually, and it is certainly possible to type 'pyb.delay(10000); pyb.bootloader()' to give myself time to exit gra...

I saw the tear-down approach and jump to DFU, we set a magic byte instead in SRAM and reset and branch on to dfu, much easier.

Also fixed it in my repo and confirmed working with Py3

Yes it doesn't matter where it lives, as long as it's somewhere in the same repo.

Awesome! no it won't fit, it's about 26mmx34mm Hmmm, if it is 26mm wide, it might... If it weren't for the SD card sticking out the side, it would fit. That implies I could possibly use it as a down-facing sensor, but not a recording device, unless I could find a flexible uSD extension cable. I sho...

I see that there is pyelftoolls available. Perhaps reading the elf directly would be easier? I'd be willing to take a stab to integrate support for that (or for that matter supporing .dfu files). I think there's a function to parse DFU files in tools/dfu.py script ? if you would like to try that wo...

And that will have the side effect of wiping out the internal flash disk. On the pyboard, the first 16K is for the IRQ vectors and some code. Then 112K of internal disk storage followed by the rest of the firmware. Yeah I know, actually I do a mass erase first anyway, that can be improved later. Th...

Hey, I've been looking for a Python DFU implementation for STM32, but I couldn't find one, so I implemented some of the DFU protocol here: https://github.com/iabdalkader/openmv/blob/master/usr/pydfu.py Unlike dfu-util this actually exits DFU mode and jumps to the main application after finishing the...

I was thinking RC submarine : D Well, I'm still working on my autonomous submarine that runs MicroPython. http://forum.micropython.org/viewtopic.php?f=5&t=218 I don't think your board will fit inside though - the inside diameter of the shell is only 29mm. - Jon Awesome! no it won't fit, it's about ...

Hi, nice. What exactly was the task of the board? I was playing with the idea to control a little zeppelin with the pyboard. Small enough to let if float around in the entrance area of the university main building. I struggle to find light enough components (the pyboard is small and light enough), ...
