Yes, it's for the bootloader.

The application need to modified to match the smaller size (16kB) as well. Basically the IRAM1 Start + IRAM1 Size = 0x4000. THe IRAM1 Start address is varied, depends on the configuration of your application. You will have the suggested RAM requirement when you enable the softdevice, please check the log.

The bond information I mentioned was about sharing the bonding key between application and bootloader, if you don't need that (it's not implemented in SDK v12) you can ignore it.

Thanks

This is for the bootloader ?

any input regarding the application ?

what is the "bond information" ?

Thanks again

Hi Eran,

I assume you want to modify the RAM setting to match with your 16MB RAM chip ?

If it's the case, please set the RAM setting as:

IRAM1 Start: 0x20002C00

IRAM1 Size: 0x1380

You don't need to set IRAM 2 if you don't plan to pass bond information to the bootloader (which doesn't support in SDK v12.3)

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 ...

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 !
