Hi Good Day,
I have been able to use the DFU Flash bootloader to refresh the application,
This method is to press the button before each power up, when the bootloader detects the button is pressed, it will perform the update action.
The question is, is there any way to jump from the application to bootloader mode, instead of using the above method.
There is a JumpToBootLoader function in the "boot_demo1" sample code,
By following this method, the system hangs.
Thank you.
