DA16200_DA16600_IMG_FreeRTOS_v3.2.8.1

Hi,

I'm completely new to the DA16600 - is there any documentation on the images contained in the 'DA16200_DA16600_IMG_FreeRTOS_v3.2.8.1' download? The '_ATCMD_' images I can guess, but what is 'DA16600_IMG_FreeRTOS_QFN_v3.2.8.1_4MB'? The readme file gives no clue.

Thanks,
