Hello,
The following is for a custom application but I have also tested this with the base peripheral_uart example with the same result.
I have an application which uses a custom firmware on both the application core and network core and have configured the app project with CONFIG_BOOTLOADER_MCUBOOT and CONFIG_PCD, configured the net project with CONFIG_SECURE_BOOT, and added the net as a child image to the app to successfully build and produce app_update.bin and net_core_app_update.bin.
When the DK is placed into DFU mode and connected over USB, I am able to use mcumgr to send app_update.bin to the APP core. The console displays the following:
I: Erasing sector at offset 0x0
I: Writing at 0x0 until 0x124
.....
However, when I try to send net_core_app_update.bin, I get the same output as above and after reboot the serial console shows that I enter a bootloop from what I assume is mcumgr incorrectly writing the net image to the app flash.
Is there any documentation available on how to instruct mcumgr to write net_core_app_update.bin to netboot over IPC or otherwise update the NET core over MCUBoot's USB connection.
