Hello,
Issue: after successfully compiling, generating bootloader settings, merging and flashing bootloader+settings+sd+app, the device enters DFU mode while i was expecting to run the app.
I'm developing a solution based on a nRF52832 with a custom board, softdevice S112 version 7.0.2, with SDK 17.0.2.
I have successfully built the micro_eec library, and bootloader from $(SDK)/examples/dfu/secure_bootloader/pca10040e_s112_ble.
My app is tested working when flashing with no bootloader (erase device, flash the softdevice and app). My app also uses two flash pages to store data, as per this definition:
Bootloader setting is generated successfully with the following line:
Here is the output:

i have no warnings when merging (ie, no overlap)
Thanks,
Martin
