Hi,

Which SDK version and Softdevice version are you using? It seems that you have changed the memory setting when I compare the standard example from the SDK with yours. I also see that you haven't defined the mbr_params_page memory region. Could you try changing it back to the original setting? If that doesn't work, could you try changing it to as in Keil?

regards

hi Jared,

to jump to bootloader i set GPREGRET register and then call soft reset. so i can't set debug point there. Here is my config in keil

(edit: sorry, i posted the wrong picture)

Hi,

Set a breakpoint in the function, it should be called when you try to enter DFU mode.

[quote user="Dien Nguyen"]Because if i build hex file using keil ide and flash it to chip, my program is working, but if i use gcc it always jump to bootloader program. [/quote]

Could you share a screenshot of the memory settings that you use in your keil project?

hi Jared,

i use SDK 15.2 with softdevice 6.1.0

Could you step through dfu_enter_check() and check what's requesting the DFU mode?

how i can check this, call it in main program? Usually i have bootloader hex file, use Jflash to burn softdevice and bootloader hex file into chip. After that i can use keil to load program or use Jflash or use nrf connect (all work). Because if i build hex file using keil ide and flash it to chip, my program is working, but if i use gcc it always jump to bootloader program. So i think have some config not correct or i miss something :((
