build/logitacker_aprdongle.uf2 version v0.1.4-beta appears to be corrupted #10

Closed fraabye closed 4 years ago

fraabye commented 4 years ago

This binary does not appear to be working with the April Brother dongle as the v0.1.3 did. Steps to reproduce:

  1. Connect April Brother nRF52840 Dongle as removable drive NRF52BOOT.
  2. Copy logitacker_aprdongle.uf2 to the mounted drive.
  3. Expected outcome, a disconnected device / reflash, does not happen and the drive NRF52BOOT drive stays mounted.

The dongle has been tested successfully with the v0.1.3 build afterwards.

I re-tested the firmware, just now, and can't reproduce the issue.

File used was the on this one: https://github.com/mame82/LOGITacker/releases/download/v0.1.4-beta/logitacker_aprdongle.uf2

The firmware in use before flashing v0.1.4 was v0.1.3, too.

Additional note: The dongle fails to reboot after flashing.

Behavior observed:

1) Put dongle in bootloader mode (hold button while plugging to host) 2) Copy firmware to NRF52BBOT 3) Dongle LED starts blinking while flashing 4) NRF52BOOT mount disappears and dongle stops blinking (flashing finished), but doesn't reboot 5) After re-plug of the dongle, LOGITacker boots as intended

Question:

Could it be that you accidentally copied the logitacker_aprdongle.hex file instead of the UF2 one, from the build directory?

It turned out to be a proxy mangling the firmware during download. After re-downloading it (again) using a direct connection it works as expected. Sorry for the inconvenience!
