I am on the DK-52 with the SDK 13.0.0.
After erasing the device, I follow this steps:
1) upload the softdevice
nrfjprog --reset --program s132_nrf52_4.0.2_softdevice.hex --family NRF52
2) upload the bootloader (bootloader_secure_ble)

I'm trying to determine DFU_APP_DATA_RESERVED and FDS_VIRTUAL_PAGES. According to this Q&A, DFU_APP_DATA_RESERVED must be the same FDS_VIRTUAL_PAGES, if FDS_VIRTUAL_PAGE_SIZE is 1024.
My application uses 11 pages, so 11+the size peer manager uses must be FDS_VIRTUAL_PAGES( and DFU_APP_DATA_RESERVED ... (more)

It would make sense to start ...
