With this application setting, when i upload application.zip file through bootloader, then application file is not uploaded and process is not getting completed.

No bootloader found issue is coming.

So the ble_dfu_buttonless_async_svci_init() call in the application is still generating ERROR 4 [NRF_ERROR_NO_MEM]?

Can you post the .map files for the compiled application and the bootloader?

Best regards

Bjørn

If you are using the following settings

FLASH_START=0x78000

FLASH_SIZE=0x6000

for the application then that is incorrect. It should be

FLASH_START=0x26000

FLASH_SIZE=0x52000

Thanks for reply, I think you are misunderstanding my settings for bootloader and application.

in boot-loader setting I have not changed any things.

These are my application settings,

FLASH_PH_START=0x0

FLASH_PH_SIZE=0x80000

RAM_PH_START=0x20000000

RAM_PH_SIZE=0x10000

FLASH_START=0x78000

FLASH_SIZE=0x6000

RAM_START=0x200057b8

RAM_SIZE=0xa848

After this setting I got error the below error,

Are these the settings for the application or the bootloader. You need to modify the application settings to the following

FLASH_PH_START=0x0

FLASH_PH_SIZE=0x80000

RAM_PH_START=0x20000000

RAM_PH_SIZE=0x10000

FLASH_START=0x26000

FLASH_SIZE=0x52000

RAM_START=0x20002230

The settings for the bootloader should be left as they are.

Hi,

Thank you for Replying I changed starting flash and size of flash as you told as like shown below,

FLASH_PH_START=0x0

FLASH_PH_SIZE=0x80000

RAM_PH_START=0x20000000

RAM_PH_SIZE=0x10000

FLASH_START=0x78000

FLASH_SIZE=0x52000

RAM_START=0x20002230

RAM_SIZE=0xddd0

In this I got 24 error as shown below,

.text is too large to fit in FLASH memory segment
.sdh_soc_observers is too large to fit in FLASH memory segment
.sdh_ble_observers is too large to fit in FLASH memory segment
.sdh_req_observers is too large to fit in FLASH memory segment

In bootloader code RAM and Flash adrees is as shown below,

FLASH_PH_START=0x0

FLASH_PH_SIZE=0x80000

RAM_PH_START=0x20000000

RAM_PH_SIZE=0x10000

FLASH_START=0x78000

FLASH_SIZE=0x6000

RAM_START=0x200057b8

RAM_SIZE=0xa848

So please give me some suggestion as soon as possible.

You need to modify the FLASH settings to free up space for the bootloader. The default settings reserves the entire flash from 0x26000 (end of SD) to 0x80000 ( end of flash). You are basically erasing the bootloader when you're flashing the application

You need to change FLASH_SIZE to 0x52000 to free up space for the bootloader, which starts at 0x78000. Hence, the FLASH_SIZE must be 0x78000-0x26000= 0x52000

Best regards
