Default "Hello world" program stalls on V2 after scrolling the text, and doesn't display the heart image. #82

Here are saved hexes: microbit-program.zip

Both hex files in the zip file work fine for me. I believe both hex files were generated with the Python Editor, right? Did you flash the hex files via BLE? Or do they file on your environment via drag&drop as well?

Noticed first in iOS, then created those files in Windows and dragged them to micro:bit. Tried it several times with beta and live. Very odd. I'll try a different micro:bit.

Sorry! It's just one micro:bit that fails (a retail one):

This is an RC1 that works (seems identical?):

I've tried some variations. If I display an image first, the image is frozen on the display. With the scrolling text first, the display is left blank.

carlosperate commented 3 years ago

Right, and with this specific micro:bit the problem happens with BLE and drag&drop flashing? Does the same problem happen with WebUSB flashing?

martinwork commented 3 years ago

Yes, WebUSB is the same.

martinwork commented 3 years ago

I guess it's a fault in the micro:bit
