MicroPython
Downloaded MicroPython to stm32h7b3i-dk board, but not able to save code #11584

Hi, with stm32 programmer on Windows. I fired up Thonny (3.3.13) editor (which I've been using for RPi Pico uPython work) and was able to select Generic Micropython. REPL started with this line: but I couldn't save my source file (like blinky.py) to the STM32H7B3I_DK. Has anyone run into this issue before, and does a solution already exist to get it working? Also, do I need some kind of BSP file to get it to work? Much appreciation for any pointer you can provide! Benjamin |

If you have a REPL then that should be all you need to copy files. How are you connected to the board, is it via the ST-Link UART or via the USB VCP?
What do you mean by "couldn't save". What goes wrong?
The MicroPython-equivalent of the BSP is what generated that firmware image. i.e. https://github.com/micropython/micropython/tree/master/ports/stm32/boards/STM32H7B3I_DK Thonny doesn't need any board-specific logic. Either way, can you try copying files using |

Argh missed something else. The H7B3 has 8kiB sectors. Here's another updated firmware.hex. |

(I suspect there are likely to be more issues. It's a bit pointless without an actual board to test on. @dpgeorge has one, so I'll leave it with him to continue from here.) |

@jimmo @dpgeorge Thank you both for the hard work. REPL still has not come back with any of the firmware.hex (including the one from 9 min. ago). Still, appreciate all the time you have spent on this issue. I'll wait for the good news from Damien then :-). Meanwhile, I'll play with the original version on the micropython site (with which REPL comes up) to play with the other features of the board. Benjamin |

@4riceotter here's a firmware.hex (from @dpgeorge) that will use the external spiflash (in regular, not octal mode). But should be enough to get you a working filesystem. I don't know when we'll get around to supporting the internal flash on this chip properly (the H7B has some extra quirks over the the rest of the H7 family). It's quite similar to what we need to do for the H5, so probably follow #11138 for updates. |

It works! You guys are wonderful @jimmo @dpgeorge :-)! Thank you, thank you! Benjamin |
