Add usb bootloader to ble bootloader.

[Hannibalhz]

Dear Nordic Engineers

I would like to add usb bootloader to ble bootloader.

I modify config of pca10056_usb_debug/sdk_config.h and  add .c .h file of  pca10056_usb_debug to pca10056_s140_ble.

After I  encounter some errors:

Pls. give some good suggestion on how to solve these errors?

I will share this program to help other people.when this program is solved.

Best regrads.

Hi Wang, 

Could you let me know what exactly you did by " pca10056_usb_debug/sdk_config.h and  add .c .h file of  pca10056_usb_debug to pca10056_s140_ble."  ? 

The error is suggesting that the flash size configure for the bootloader is not enough to handle both the USB and BLE transport layer. 

What you need to do is to increase the size of the bootloader. To do that you need to move the start address of the bootloader down, for example instead of

FLASH_START=0xf8000

FLASH_SIZE=0x6000

You can change it to 

FLASH_START=0xf6000

FLASH_SIZE=0x8000

Dear Bui

The following file is my project.

I will try to change to

FLASH_START=0xf6000

FLASH_SIZE=0x8000

It displays some new errors:

Hi Wang, 

Have you tried to increase the flash more ? 

Note that if you use Oberon library it will require more flash space. 

Please state the SDK version you are using. 

[Hannibalhz]

Dear Bui

I use NRF5 SDK 17.1.0.I will try to increase the flash more.

Please help me review my project.Does it have other problem?

Thank you

Best regards.

I tried to build your project but it got another issue: 

I would suggest you to have a look at this case:  Official BLE and UART Combined DFU bootloader? There is an instruction on how to do it. 

And I also made an example here , it's for UART and BLE in SDK v15.2 but it's a good source of reference.
