FDS fails to initialise with bootloader present

[RPDben]

Hi,

I am getting a strange issue in my code where my FDS will run fine if there is no bootloader but fails to initialise if there is a bootloader present. I am using SDK 17.1.0 and S140 V7.2.0 on an nRF52840. I am using the pca10056_s140_ble secure bootloader example from SDK 17.1.0 unedited.

The error I am seeing is the function fds_init() returns with error code '0' (Success) but the FDS Event Handler is never invoked to say the Init has been complete. Without the bootloader present, the same code runs fine and the Event handler is invoked as expected.

Any help on why this might be the case would be much appreciated.

Hi,

Which application are you testing with?

I just tried out the flash_fds pca10056/s140 example from SDK 17.1.0 together with the S140 secure BLE bootloader on nRF52840 DK, and this works fine.

Are you using the softdevice or NVMC backend in your FDS application? Are you enabling the softdevice in the application before using FDS?

Best regards,
Jørgen
