Upgraded to bootloader breaks Trinkey M0

Post by techman »

Update:
I was able to find and flash the current bootloader:

Issue resolved. Sorry for the noise.

Original message:

No thinking through everything, I managed to update the boot loader on 9 out of 10 of my Trinkey M0 devices, I can get into the boot loader, with double click, I can load circuit python no issues, but there must be some check in circuit python that enables the internal modules based on what it sees in the bootloader, is there a UF2 bootloader file for the Trinkey M0 that I can reload on the keys?

They came with:

UF2 Bootloader v1.23.1-adafruit.1-337-g1c691d5 SFHWRO
Model: NeoPixel Trinkey M0
Board-ID: SAMD21E18A-NeoTrinkey-v0

I have managed to load:
UF2 Bootloader v3.13.0 SFHWRO
Model: Trinket M0
Board-ID: SAMD21E18A-Trinket-v0


Thanks in advance.

So, you're OK now? Not sure if you got it fixed.

Yes, the issue is resolved.

Silly mistake on my part, once I found the correct bootloader I was able to fix it pretty quickly.
