Essential Tips for nRF54L15 HEX File Verification

Hi readers, did you know that Raytac offers a special service exclusively for our customers? 😉
We offer support services: HEX file verification and flashing firmware into modules per customer’s requests.
Compared to the series nRF52 and nRF53’s 2 in 1 or 3 in 1 merged hex files, nRF54L15 requires something slightly different. Following are the tips and suggestions.

Before building your own .hex file on Raytac’s nRF54L15 modules(Product link), please configure some settings(shown below) in advance.

In VS Code:

  1. Go to Add Build Configuration
  2. Find System Build (sysbuild) ➝ Choose Build System Default
  3. Click Generate and Build


Starting from NCS v2.8.0 (including later versions), the .hex file can be generated in two different paths.
1. ..\nrf\samples\bluetooth\application-name\build\merged.hex
2. ..\nrf\samples\bluetooth\application-name\build\application-name\zephyr\zephyr.hex



Using the AN54LQ/AN54LV series as an example:
When you provide the programming file (.hex) for production, please ensure that the file is taken from the following path:
1. ..\nrf\samples\bluetooth\application-name\build\merged.hex
And we also do not recommend renaming the merged HEX file due to Nordic suggestions.

For more details behind this suggestion, please refer to the Nordic DevZone link below.
https://devzone.nordicsemi.com/f/nordic-q-a/120313/how-to-modify-the-name-of-the-merged-hex-file


Suggested path:
1. ..\nrf\samples\bluetooth\application-name\build\merged.hex

Not recommended path:
2. ..\nrf\samples\bluetooth\application-name\build\application-name\zephyr\zephyr.hex
The zephyr.hex file is not recommended to be used for flashing or verification in the production process.

Thank you all for your patience in reading!
Best wishes for your projects – your success is Raytac’s success! 😊

How To USE Nordic Connect SDK (NCS) Flashing Built Code into nRF5340 Module

Edited by Jocelyn Tsai / Account Manager

Intro:  With the ready built code of zephyr.hex file for net core and application core individually, we would like to proceed code flashing into the MDBT53/53V Nordic nRF5340 BLE module.

  • Ready Built Code Programming Steps

Step1. 

Execute nRF Connect >>  Programmer  > > Open

Step2.

Click “SELECT DEVICE” >> Find icon of “nRF5340 DK” which is detected by the programmer app

Step3.

Click icon of “nRF5340 DK” >> “Erase All” to remove the flash memory from MDBT53/53V BLE Module

Step4.

Click “Add File” to load the net core zephyr.hex and application core zephyr.hex both into programmer

Step5.

Do “Erase & Write ” to execute the flashing process for both zephyr.hex into memory of MDBT53/53V Module.

Step6.

To validate the wireless broadcast of default name “Nordic_UART_Service” from MDBT53/53V Module, please check on the “nRF Connect for mobile” APP and do “Scan device” through your mobile.   

Once the device name is detected in your mobile , the wireless connection is successfully done.
