nrf52805 file merge error (SD/appl/bootloader/settings)

[air]

Hello,

I'm developing using below condition.

- SOC : nRF52805
- SD : s112_nrf52_7.2.0_softdevice.hex
- SDK : nRF5_SDK_17.1.0_ddde560
- DK : PCA10040
- compiler : IAR 9.40.1

I am creating a DFU package and SD/appl/bootloader/setting merge file.

An error occurred during file merging.

I would like to inquire about this

Also, when creating the package file in Step 8 and the setting file in Step 9 below,

please check that the information such as version matches that of the nRF52805.

Thanks.

Hi

From looking at your .hex files it seems the starting address of both the ble_app_proximity.hex and the secure_bootloader_ble.hex files are at 0x0000. I'm not an IAR expert, but I think you need to set the start address in the flash_placement.xml file or similar placement settings option in IAR. There are multiple previous cases on this already on DevZone, so please see through these cases: https://devzone.nordicsemi.com/search?q=bootloader%20starting%20address 

Best regards,

Simon

The part where the starting address of the application/bootloader area was incorrect was corrected.

After merging, an error like the screen below occurs.

All erase is performed before flash.

I add the sdk_config.h file, command used when merging with the address area currently in use below.

1207.sdk_config.h

I would like to get help on which part I should check.

/*-application Regions-*/
define symbol __ICFEDIT_region_ROM_start__ = 0x19000;
define symbol __ICFEDIT_region_ROM_end__ = 0x27fff; // old:0x2ffff;

/*-bootloader Regions-*/
define symbol __ICFEDIT_region_ROM_start__ = 0x28000;
define symbol __ICFEDIT_region_ROM_end__ = 0x2dfff;

Hi

So it seems the application starts at least and now it just seems to be an issue with your application running. There are quite a few cases with this error reported already in the DevZone so I suggest checking out some of those. 

https://devzone.nordicsemi.com/search?q=NRF_ERROR_STORAGE_FULL 

It seems like you might need to restore the UICR registers used by your app/bootloader perhaps as described in this case specifically.

Best regards,

Simon
