Not able to communicate with the Bootloader while using Serial recovery example on Custom board

[Tamizh]

Hi,

I've integrated the nRF52840 SoC with my custom board(IMX6-ULL). I want to implement the serial recovery method for DFU mentioned in this GitHub project created by one of the Nordic Members which I got from another  DevZone post.

https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/serial_recovery/mcuboot_serial_recovery_uart

I'm able to implement both button-based and timing-based methods mentioned in the above link on the nRF52840DK without any problems. But while implementing the same on my board with a custom UART overlay, I'm unable to use mcumgr as it is giving an NMP timeout.

My board doesn't have a button for triggering recovery mode, so I tried the wait method and I can see that the Bootloader is waiting for 5 seconds(Specified wait time) before loading the application as expected. But this step not working

Any suggestions?

Thanks.
