DFU Bootloader with S120 config

[Gabriel C.]

Hello,

I started to make an app for a board with nRF51822 with softdevice S120 version 1.0.1. Now I would like to have the DFU implementation in it but I am stuck at the project configuration.

Still quite new and I don't know how to solve this problem.

With version 1.0.1 I had this memory configuration:

Now, as @hungbui explained in this answer and from his example, I got this memory set-up:

If I let it like this, I got like 200 errors, as all the files and implementations I have already does not fit in that memory size.

If I change the IROM1 size to 0x27000, it compiles without errors, but when I try to Download it on the board, I get the error message:

Erase Failed! Error: Flash Download failed - "Cortex-M0"

Any help would be much appreciated.

Thank you.

@ Gabriel: Seems that you are using pack. The example I provided is with the .zip SDK, not the pack type.

You can download the .zip SDK here

My example was based on SDK v8.0 and support S120 v2.0.0. You would need to port it to be compatible with S120 v1.0.0 or you can try to port your application to S120 v2.0.0. I would suggest you to do the latter one. You can follow the migration guide in the S120 v2.0.0 zip file. It should be straight forward.

To have the bootloader to work, you need to flash the sofdevice first, after that flash the bootloader. And use the bootloader to update the application firmware.

Thank you! I will try to port it following the steps you mentioned!
