Solved - Dead duet wifi board???

As TCK is right next to GND on the 2x5 pads where you connected the resistor, a solder bridge between those pads is the most likely explanation.

finally figured out!

i've followed the instructions on the wiki page https://duet3d.dozuki.com/Wiki/Connector_and_spare_part_numbers#VSSA_fuse for bypassing the fuse and add the 10K resistor, and solderd by this image on the wiki:

But!!! that picture is wrong!!!! the resistor is NOT going to the TCK, is connected to ground, as my board recently. The pad to the left is the TCK pad!

how do i know?

The proof...

So now my board is not dead, but upgraded!

The processor swap was relatively easy. if anyone wants more details, i've made a video of the process.

You are right, the labels next to the 2x5 pad array are wrong. The two columns should be swapped.

And the wiki should be updated
