thank you , i change the stack_size to 1870,it's ok.thank you very much.

and i know in the SDK9.0,i can let it DFU by set the NRF_POWER->GPREGRET =BOOTLOADER_DFU_START(0xb1).and i want to use the same way in sdk12.3,but when i let NRF_POWER->GPREGRET =0xb1,it reset,and start application again,not in dfu mode ..and i test i really write the NRF_POWER->GPREGRET =0xb1,i printf it

You should only have to change the RAM settings so that

IRAM1 Start: 0x200025E0 Size: 0x1A20

Which error are you getting? Are you using the test images in the SDK or have you generated your own zip file? Could you try using the test images found in examples\dfu\ble_dfu_send_hex\test_images_update_nrf51? If you generated your own zip, which version of nrfutil are you using to generate the zip file? Also please post the nrfutil command you used to generate the zip.
