OTA DFU on NORA B1

[Jirik]

Hello,

I have a project working on Nora B1, which I am testing on nrf5340DK. It is based on the Peripheral UART Sample, programmed with nfr Connect SDK v1.9.1. Now I need to add the OTA DFU to update the program from the nrf Connect mobile app. I changed the prj.conf and main according to this tutorial

https://getwavecake.com/blog/adding-ota-dfu-to-a-nordic-zephyr-project/

It works perfectly, when I am testing it on the Development Kit, but it does not work at all on the Nora B1. The flash is succesful, but the BLE can't get initialised.

I tried a bit and it seems like the problem is caused by the line

CONFIG_BOOTLOADER_MCUBOOT=y

when I add this to the prj. conf, BLE does not work, even when I did not do any changes in the main.

Is there anything special I should take care about while configuring bootloader on the NoraB1?

Thanks a lot for any answer

Hello,

Could you share your whole configuration and overlay files here? I will take a look. If you have a pm_static file, then please share that too.

The path or file name I mentioned in the above response is wrong. You can change the mcuboot configuration either by child_image/mcuboot.conf or child_image/mcuboot/prj.conf. See the page Multi-image build.

Hello Abhijith,

Thank you for the hint with the path, I already implemented it in my previous applications, so it was not the problem.

I am sending you the whole project, it is the the lbs_ota_dfu_withoutextflash you sent me, with my changes to make it uploadable on the NORA B1 (which unfortunately does not work) to avoid the problem with the external flash. Please take a look at it.

Thank you a lot for the support.
