Stuck in bootloader

[dyaa]

Hi, I've got my hands on pga2350, and i connected it using Adafruit usbc breakout board exactly this way, got the volume after booting with bootsel and all is fine until here.

I've copied many different uf2 files from the latest 2 releases related to the pga2350, yet it keeps rebooting into the bootloader, and picotool info seems to only see the device information giving me a sense that micropython did not boot

I can only see the volume, but nothing coming in ls /dev/tty.*

any idea how to unblock this and have micropython up and ready? thanks in advance

The non “with-filesystem” builds should work!

The “with-filesystem” builds from here should work too - https://github.com/pimoroni/pga/actions/runs/10901460006

Will double check this tomorrow and tag a new release!

Any update @Gadgetoid? 🙏

[Gadgetoid]

Looking at this now...

Edit, okay that's weird, I flashed pga2350-psram-acc6c23479941ec994419b729c76ad9cbd768b8a-micropython-with-filesystem.uf2 and it did, indeed, seem to stall and not automatically reboot at the end of the flash.

After a wait and a manual reset:

> MicroPython feature/psram, pga2350-psram acc6c23479941ec994419b729c76ad9cbd768b8a on 2024-09-17; PGA2350 (PSRAM) with RP2350

I wonder if it has stalled waiting for the last block.

If I flash pga2350-psram-acc6c23479941ec994419b729c76ad9cbd768b8a-micropython.uf2 then it will reset as normal and show up with no problems.

[Gadgetoid]

Hmm I think there are still some issues with my with-filesystem firmware builds, but those don't explain why you're not seeing a working MicroPython.

The reboot bug is because I'm reporting one too many blocks in the with-filesystem UF2, so it just sits forever waiting for the next block... which never comes. Got sidetracked with sparse UF2s (removing the zero padding between app and filesystem) but will fast track a fix for this bug.

Tested that, and it worked, I believe indeed with-filesystem might have an issue.

I believe indeed with-filesystem might have an issue.

Still poking it today, juggling the filesystem builds not working with my board/Thonny refusing to list the filesystem, or refusing to connect at all.

That said the with-filesystem build is effectively useless unless you fork this repository and add your own customisations! (and currently broken, since no files get included 🤦)
