Nice! Is there a way to select and flash a custom built firmware from a local file system? |

I've been thinking about it, but its not there yet, but the setup allows for it to be added without too much effort. |

Looks really impressive, great job. I look forward to testing it more when I've got a supported board connected :-D |

Looks great @Josverl! Just installed (on WSL2/Win10) using I put it through a very tough test case: Traceback (most recent call last):

raise MPFlashError(f"No board info found for description {descr}")
mpflash.errors.MPFlashError: No board info found for description ESP32C6 module with ESP32C6Message could be friendlier but the raised exception is correct. :) I'll continue trying it out... |

Hehe @mattytrentini I tried the exact same thing earlier today, had the same conclusion about the message and raised a new issue on @Josverl repo tracker :-D |

This issue is fixed, boards for which the description cannot be resolved are reported as UNKNOWN_BOARD in the output table or Json. |

you can add There are quite a few UNKNOWN_BOARDS, do you have all these defined in a local micropython repo ? |

the recent rename of the board_id aka folder names for the rp2 and esp32 / esp8266 have caused me more than a little headaches in matching the same boards before and after the rename occurred. especially as the rename has been done retrospectivly for micropython.org/downloads I'll look into it - and start by improving the tests |

@scruss , the issue was not what I initially suspected. When specifying a --board , but no --port for download, there was no code to lookup the missing port(s) from the board. |

Hi again, I connected up an old rpi pico board and tried an mpflash list and things look more promising. So maybe just something to do with my ESP32 in the previous test. For the pico I get the following:

To round off the test on the rpi pico, no luck so far. I had done a mpflash download and it downloaded the appropriate mp. I then did a mpflash flash and got a choice of port / board to select but got some errors about something would only run on linux when appropriate choices were made. I did not take a note of this as to start with I wanted to get rid of some of those ports I no longer use as your program took some while to examine them. Now, whilst I can see the pico in the mpflash list, a mpflash download reports already downloaded, but a mpflash flash now never gets to the point of providing a list of what to flash. I always just get the following: |

Thanks for the test and logs so far On the extra serialports, there is an - - ignore switch to avoid wasting time on them. I already try to filter out serial over Bluetooth, but that did not work in this case. On the esp32 board, it appears that it did not have micropython on it. I need to find a way to make that discoverable somehow. For the rp2 I'll open an issue, lest continue the conversation there. |

Interesting tool. It doesn't exactly match my usecase (I grab a custom image from a specific URL and flash it) so I started some tinkering. I extended both the download and flash commands with a --raw option. Worked fine for my rp2040. Weeding through the code is a bit frustrating, it is very much tuned to the specific usecase of first downloading and then flashing multiple boards of multiple types. After the rp2040 I tried an esp32, but the tool doesn't recognise the particular board "ESP32_UNKNOWN_BOARD". Correcting that seems to require a deeper dive that I want to commit to today. For now, I give up. |

The board options all seem to be for specific boards. I don't think you will ever get those lists complete. In most cases I don't care for a particular board. Could you (for each port) add a generic board? (and for the esp32's for which this is relevant: with and without spiram) You call 'esp32' a port, but I think its should be esp32, esp32c2, esp32c3, esp32s2, esp32s3, etc. Otherwise you'd need generic boards for each of those chips. |

OK. The MicroPython repo has 'generic' targets. Could you include those? |

AFAIK Only the ESPxx have GENERIC targets -and they are already included - but variants may be missing. A quick few samples:

About SAMD: A fresh SAMD board with the uf2 bootloader installed only switches to .UF2 mode by pushing reset twice at the proper pace, whatever it is. Once MicroPython is installed, one can use the touch1200 method: switch USB serial speed to 1200 boad and back to 115200. |

The 1200-bps-touch reset can be enabled in most ports I think, though it's not on by default on many boards. I think it's a usage pattern common on Arduino and/or Adafruit gear? Do a global search for |

looking back up the thread it seems like this may be another case of macOS and Bluetooth serial ports not being known about. It would be great to have a "known to never have a MPY board on it" list of ports to skip, it would make things much quicker 🙂 |

This behaviour is not expected: It does not make sense (to me) that it is scanning those ports when I've explicitly told it which serial port to target? Additionally, I actually would like to flash a Pimoroni build of MicroPython onto |
