Firmware upgrade of hci_uart app by using bootloader in serial recovery mode #ble #nrf52480 #uart #hci

Hello,

I have nrf52840_pca10056 chip connected to imx6ul processor via uart (Both are embedded on my custom board) as shown in attached image.
I'm using mcuboot bootloader on nrf52840 chip, now i want to flash hci_uart app over UART by keeping mcuboot in serial recovery mode.

NOTE: I do not want to go with other way of upgrading the firmware (Using smp_svr application).

Q: So what i need to do to upgrade the firmware using bootloader's serial recovery mode ?

(I do not have any physical access to the pin for nrf52840 chip).
