Firmware Flashing fails

Question

whoot opened this issue 5 years ago · comments

Hey,

I was trying to flash the firmware 'btlejack-firmware-microbit.hex' from https://redmine.laas.fr/projects/btlejack-custom-firmware/repository to the Micro:bit.
However, it didn´t work and all i get is a textfile FAIL.TXT in the micro:bit folder which states:

In application programming write failed.

What am i doing wrong?

Hello,
This issue has already been mentionned here:
virtualabs/btlejack-firmware#8

The reason remains unknown, however the problem seems to be "solved" by flashing a genuine microbit firmware before trying with btlejack.

When you plug the micro:bit, does it appears as an USB mass storage device ?

Hi,

thanks for your response. Not pressing the reset button worked!
Maybe you should mention that somewhere in the Readme.

Thanks for your help!

Good.
I'll release a new version soon, so I'll probably add it to the readme and the documentation. Thanks for reporting this issue.
