Yes, It is failing with SDK11 as well. May I ask some post solution for the same? Br, ggotta

@chalecampb: (Alex) Are you seeing this issue with SDK v11.0.0 as well?

Hi,

Just wanted to follow up on additional testing.

Keil DFU built and installed
Prebuilt zip installed, works.
Keil-built and packaged application zip package works.
GCC-built and packaged application zip works flashing over the keil-built application (the first time).
GCC-built and packaged application zip fails (the second time).

Since the bootloader code hasn't changed, it looks like whatever method the DFU app service uses to jump to the bootloader is broken in the GCC builds.

Thanks, -Alex

Hello Alex, If you are flexible in IDE choice, then can you try to build your project in Keil? In my case it's totally working fine with same kind of configuration on Keil tool. You can use below tutorial link for reference. devzone.nordicsemi.com/.../
