dfu\bootloader_secure problem error at sd_mbr_command(&command); (nrf_dfu_mbr_init_sd())

[Ron]

Hi

Im using the DFU secure example (examples\dfu\bootloader_secure\pca10028)

Im working on a NRF51822-QFAA ,S130 SDK12.3 , Im not sure about my IROM/IRAM definitions, my settings below

I have an error at (nrf_dfu_mbr_init_sd()) sd_mbr_command(&command); 

err_code = nrf_dfu_mbr_init_sd(); (see print screen below)

Any help will be appreciated 

Thanks !

Memory definitions as follows :

error here :

Im not sure if it's relevant but UICR Register seems fine

Update :

I have tried to change the IRAM1 size moving for NRF51422-QFAC (on NRF51 DK) to NRF51822-QFAA (my HW) following your guiding here :

https://devzone.nordicsemi.com/f/nordic-q-a/16388/project-code-move-nrf51422-to-nrf51822?ReplySortBy=CreatedDate&ReplySortOrder=Ascending

subtracting 4000 from 0x5380 to 0x1380 

but the problem persist, rev_val for sd_mbr_command is still 0x200033c0 

also tried setting  IRAM2 NoInit, with and without it (as I've seen in several threads), did help

to be clear , Im using the same softdevice, 

Thanks !

after fully erasing and than reprogramming softdevice, we do as sd_mbr_command

however fail at softdevice_enable(&ble_enable_params);

in the next run it fails at sd_mbr_command again ...
