Unable to load dfu_application.zip from Fundamentals Course, Lesson 5, Exercise 2 on a Thingy:53

[rdunkijacobs]

I am using all of the latest software/firmware as of the date of this message.

Lesson tells me to follow a link to "flash" the Thingy:53.  Got to the point where the following screen from the nRF Connect For Desktop Programmer (V4.4.2) took me

The instructions that I was following come from https://academy.nordicsemi.com/flash-instructions-for-the-thingy53/ which talks about an MCUboot programming pathway.

However, the programmer screen shows that there is no way to write this file to the Thingy:53.  In fact the tool tip on the Enable MCUboot toggle says that this function was disabled due to lack of proper support.

Any thoughts on what is going on here?

Hi Robert

Your images is a bit confusing. The programmer app shows a 5340dk, while you are trying to flash a thingy53. 

To flash the thingy you should press down the button SW2 while durning on the device to start it in bootloader mode(it should appear with the name bootloader) and then you can flash it
