[Urvisha Andani]

Hello,

Greetings!!!

I am working on nRF52832 having SDK 15.3.0, Windows 7 and Segger Studio IDE.

Right now I am implement OTA in my custom application.

I upload bootloader code in nRF52832 chip successfully upload program then connect with nRF connect and using boot-loader update .zip .

After successfully upload .zip fill device not start advertise.

I got error in ble_dfu_buttonless_async_svci_init() this function as shown below,

<error> app: No bootloader was found

<error> app: ERROR 4 [NRF_ERROR_NO_MEM] at D:\nRF5_SDK_15.3.0_59ac345\nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\ble_app_full_application\main.c:1304 PC at: 0x0002BE77

<error> app: End of error report

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=0x26000

FLASH_SIZE=0x5a000

RAM_START=0x20002230

RAM_SIZE=0xddd0

So please give me solution as soon as possible.

Thanks & regards,

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

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,

.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.

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

RAM_SIZE=0xddd0

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

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,

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

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.

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?
