Which DA16600 image should I use for the basic FreeRTOS UART AT-CMD build?

Introduction:

We have a custom board that uses a RA6M4 MCU to control a DA16600 over a UART using the AT commands. The device is working fine and I can use AT commands to make connections to our AWS implementation.  I was test driving different DA16600 builds to explore the DA16600 AWS implementation.  Now I want to go back to just the standard DA16600 AT command image, but I can't identify which image to use.

The images that are available that work with my hardware implementation seem to also implement a demo application.  I'm about to dig into enabling DPM power management and want to make sure the image I'm using is not doing anything I don't expect it to.

My Question:

Is there a DA16600 image that does not implement any demo code that I can use?

Details on how I tried to find an image:

New DA16600 Image (FreeRTOS v3.2.8.0):

I went to the DA16600MOD page, and downloaded the DA16200 DA16600 FreeRTOS SDK Image v3.2.8.0.  

Inside this zip file there are 7 additional zip files:

I attempted to load and verify each of the images contained in the download hopping to find the correct image . . . 

DA16200_IMG_FreeRTOS_ATCMD_SPI_EVK_v3.2.8.0_4MB

• Not compatible with my hardware

DA16200_IMG_FreeRTOS_ATCMD_SPI_SPARKFUN_v3.2.8.0_4MB

• Not compatible with my hardware

DA16200_IMG_FreeRTOS_QFN_v3.2.8.0_4MB

• Does not contain an image for the AT25SL321 flash that's on my DA16600

DA16600_IMG_FreeRTOS_ATCMD_SPI_EVK_v3.2.8.0_4MB

• Not compatible with my hardware

DA16600_IMG_FreeRTOS_ATCMD_UART2_EVK_v3.2.8.0_4MB

• The file name suggests that this is the correct image for me to use.  This image does work with my RA6 implementation

>>> Hello World #2 ( network dependent application ) !!!

Just as a reference I captured the DA16600 firmware image that shipped on the DA16600 from a second device.
