Intro:

As the chipset of nRF5340 is built by Dual Core structure (net core and application core), we need to proceed the coding and compiling process individually to net core & application core.

After the coding and compiling process done, we could get the separate zephyr.hex file respectively which are used for BLE module FW.

 Firmware Development Steps : Code Building / Compiling

Case Study : 

A. NON-Audio Project

     nRFConnect SDK V2.6.0

     Nordic Example code – “peripheral_uart”

  1. Nordic example code of “hci_ipc” extracted for coding and we will get zephyr.hex file for net core
  2. Nordic example code of “peripheral_uart” extracted for coding and we will get zephyr.hex file for application core

Step 1. Net core Layer

1a) Activate “Open VS Code” IDE in NCS V2.6.0

1b) Select “Add an existing application” and extract “hci_ipc” file moving forward

1c) Click “Add Build Configuration” icon

1d) Select “nrf5340dk_nrf5340_cpunet” and check Nordic boards then Execute “Build Configuration”

1e) zephyr.hex file is successfully generated for net core layer if the coding process is properly executed

B. Project with Audio inquiry

  nRFConnect SDK V2.6.0

    Nordic Example code – “nrf5340_audio

  1. Nordic example code of “hci_ipc” extracted for coding and we will get zephyr.hex file for net core
  2. Nordic example code of “nrf5340_audio” extracted for coding and we will get zephyr.hex file for application core

Step 2. Application core Layer:

2a) Activate “Open VS Code” IDE in NCS V2.6.0

2b) Select “Add an existing application” and extract “hci_ipc” file moving forward

2c) Click “Add Build Configuration” icon

2d) Select “nrf5340dk_nrf5340_cpuapp” and check Nordic boards, then Execute “Build Configuration”

2e) zephyr.hex file is successfully generated for application core layer if the coding process is properly executed
