Hello all,

I am using one click method in Windows to update the firmware.
The first steps are running well, but if burning the big firmware image, the upgrade tool throws error message:
‘error while executing the burning process’
This happens in the early stage, e.g. after 2% burning of the big firmware image. (see appended log )

Does anyone now a reason why this couuld happen?

Problem solved.

The update process is controlled by a microcontroler (IAP). An ISR on the microcontroller was overloading it, causing timing problems.

Thanks
