nRF52810 production programming with CLI: Soft Device and Application

[Jackson Wilson]

(1) Production Programming using CLI:

We are entering pre-production for a design containing an nRF52810 (on Rigado BMD-330 module), and we need to know what the CLI command is to program the Soft Device and Application.

So far we have been using nRF Connect Programmer, but we need an simplified, automated method for production programming of many units.

I have searched the existing cases in the Dev Zone, but I cannot find a relevant example for the nRF52 series.  I have found this link:  https://devzone.nordicsemi.com/f/nordic-q-a/10134/flashing-softdevice-with-the-latest-nrfjprog.

I want to ensure that the steps for the nRF52810 agree with this post.

(2) Bootloader for OTA DFU:

Can you please tell me the steps required to program a bootloader to the nRF52810?  I have looked at the blog here: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader.  

However, this blog does not seem to address the step of programming the required bootloader to the device, in order to allow OTA DFU.

Also, does this bootloader allow for OTA reprogramming of Soft Device?

Thanks,

Jackson

Hi,

1) I recommend you use 'nrfjprog' through a SEGGER J-Link programmer to program your devices for production. See 'Programming nRF5x SoCs with nrfjprog' infopage. For NRF52 devices use setting '--f NRF52'.

First you should run an erase all command:

nrfjprog --eraseall

Then program the softdevice or application hex file using --program:

nrfjprog -f NRF52 --program file.hex --verify 

2) Flash the bootloader with 'nrfjprog' the same way you flash your softdevice and application. Flash the softdevice first, then the bootloader.

Best regards,

Marjeris
