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

Question

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

 However, it seems this image implements a gas leak demo, see debug below . . .

 This image is not compatible with our hardware implementation, no UART AT command control.

 However, this image also implements some demo application.

 >>> 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.

 It appears that this image also has demo code running . . .

 With none of these images you are going to be able to test the AWS implementation. For AWS please download this SDK or the pre-compiled image and follow the readme file:

 You will have to open the FreeRTOS SDK and compile the getting_started project for DA16600MOD. Then you can take the generated image files and burn your board with them. Best Regards, OV_Renesas

Hi Brian, Thank you for the replies. 
 BrianW said: This implies that there is a production firmware load for the AT CMD build. Can you either point me to the source code for the AT CMD project, or identify a production load that does not implement any demo code? 
 All the available examples can be considered AT CMD compatible. Please refer on UM-WI-003 , on section 4.1 How to Include AT Command Feature in SDK , page: 26 The most examples have a small demo running. So, you can get on the getting_started example and enable the AT commands feature. On the getting_started project, go and define the __SUPPORT_ATCMD__ definition on the config_generic_sdk.h file: Then compile and download the Image on your board. By default the AT commands are going to be on UART1. If you want to enable UART2, SPI or SDIO for the AT commands please refer on the UM-WI-003. If you have any issues feel free to ask!
