Nrf52833 stays in bootloader mode. Getting error No firmware to activate.

RE: Nrf52833 stays in bootloader mode. Getting error No firmware to activate.

Hi Sigurd,

I managed to run the application. As I mentioned I'm using a non-modified version of the DFU scure-bootloader example for the PCA10100 with the SDK16 in a nrf52833 Chip.

After some debugging I managed to get my bootloader and my application running:

Compiling the secure bootloader for the nr52833 example
Compiling the ble App UART example
Creating valid bootloader settings with nrfjprog tool
Merging everything
Flashing it in my setup

Unfortunately I couldn't figure out what I was doing wrong. I just went to the above mentioned process step by step and suddenly it worked.

Thanks a lot anyways!

BR,

Yeicatl

Hi Sigurd,

Did you eventually solved the issue? I'm running into the same problem, but so far I haven't found any solution for this problem.

I'm using a non-modified version of the DFU scure-bootloader example for the PCA10100 with the SDK16 in a nrf52833 Chip. Here a log of the RTT Viewer:

Hi Snehal,

[quote user=""]Now what I have observed is the device stays in the bootloader mode. It does not automatically go into application mode. [/quote]

Is your application booted if you reset the device manually?

Hi,

Due to the vacation, we have limited resources in our support team.
I will look more into your case, but it might take more time than usual.

Thank you for your patience.
