Not able to build mcuboot bootloader for nrf7002dk

Question

Hello, Some pertinent information: We have tested on both ncs V2.5.0 and V2.5.1, and are using zephyr toolchain v0.16.1. We also will be performing OTA similarly to the aws_iot sample project found here: github.com/.../aws_iot 
 
 We have been developing on the nrf7002dk, which we have been quite impressed with, and are getting ready to implement OTA on it. We have dealt with OTA in the past via BLE for the nrf52840, and the nrf52832. As such I tested building MCUboot for the nrf52840 on ncs V2.5.0 and v2.5.1, and there are no issues. We are getting issues specifically building MCUboot for the nrf7002dk. 
 Any help on building/flashing MCUboot onto the nrf7002dk would be greatly appreciated! 
 
 Thanks, 
 
 Joe

Hi Joe, 
 I would suggest you build the MCUboot as the child image ( CONFIG_BOOTLOADER_MCUBOOT=y ) as our samples did instead of using it directly. 
 Do you want to send DFU over Wi-Fi, Bluetooth Low Energy, or serial? If using Wi-Fi, you can refer to the AWS IoT sample and Azure IoT Hub sample which support both the nRF7002DK and FOTA over IP.
