I'm attempting to put together a template solution file for the RP2040 that will at a minimum, compile cleanly and load onto the device. I've gone through the process within Embedded Studio to create a new solution and selected the RP2040 as the target processor and then Embedded Studio has generated a shell program. The shell program does compile cleanly but it fails when I attempt to load the binary onto the device.
This is the output when I connect my J-Link EDU Mini:
Display All
To me, all looks good at this point. But here is the additional output when I attempt to download the binary to the target device:
Display All
So, am I missing something or am I doing something wrong? Any help will be appreciated.

P.S. I'm using the Sparkfun MicroMod ATP Carrier board with the MicroMod RP2040 module for my development. I'm not sure if this has anything to do with why the flash is not being programmed so I'm comparing this setup with the Pico module to see if there's any explainable difference.
