Flash layout on micro:bit V2 #18127

I assume you're using the "microbit-foundation/micropython-microbit-v2" Try changing the src/codal_port/filesystem.ld and recompile. Compiling with this gave me: The gap at the beginning (0x00000..0x00fff) is for the bootloader. I do not have microbit v2 board, so I cannot test the firmware. |

I've been experimenting with changing the file system size and position. When I make it bigger it works for a while and then it gets corrupted after more file operations (in Thonny). That made me curious if there was anything else in the 0x7xxxx space conflicting with it. Is there a bootloader on both the interface microcontroller and the main (target) microconctroller on the micro:bits? |

I don't know, but there must be a good reason why the file system ends at 0x73000. Perhaps other underlying subsystems are using the space between 0x73000 and 0x7ffff. My guess is as good as yours: bootloader, softdevice, codal_app, etc. |

What's stored in the flash storage on the nRF52833 main microcontroller for MicroPython? When you compile it there's a handy little table at the end. Is this a complete picture? Why is there a gap at the beginning (
0x00000to0x00fff)? Does anything else get put in the0x73000to 0x7ffff` gap?Beta Was this translation helpful? Give feedback.
