RE: It couldn't startup application after move application from region2 to region1

Hi Hung Bui,

I used the SDK12.2(52832), and modify the example Nordic 52832\nRF5_SDK_12.2.0_f012efa\examples\dfu\bootloader_secure.

I remove the ble dfu and firmware check function, only save boot function.

This is my test step:

In this case, it could not startup success. If do not to do setp 3, it will startup success.

And I found some difference if changed keil download address and build it, the build hex file will difference.

So I want to build a firmware that the download address is region 1 but download the firmware to region 2 address.

Is there another(not keil or nRFgo studio) way can I download the appilcation(build address is region 1) to region 2 address?

Thanks!!

Hi Kevin,

How do you do DFU update ? Do you have a bootloader ? Do you use our bootloader ?

How do you start your application at region 2 ? Do you have any kind of vector table forwarding ? Do you use our softdevice ?
