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 :
NON-Audio Project
nRFConnect SDK V2.1.2
Nordic Example code -“hci_rpmsg” & “peripheral_uart”
- Nordic example code of “hci_rpmsg” extracted for coding and we will get zephyr.hex file for net core
- 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 V2.1.2
1b) Select “Add an existing application” and extract “hci_rpmsg” 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
Step 2. Application core Layer:
2a) Activate “Open VS Code” IDE in NCS V2.1.2
2b) Select “Add an existing application” and extract “peripheral_uart” 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
