Using the same method to upgrade nrf52832 will be successful, but nrf52840 will fail

No, the bootloader I use is nRF5_SDK_14.2.0_17b948a \ examples \ dfu \ bootloader_secure_ble \ pca10056_debug \ arm5_no_packs \ _build \ nrf52840_xxaa_s140.hex;
The softdevice used is Flash_s140_nrf52840_5.0.0-2.alpha_softdevice;
Use Keil to burn the softdevice and bootloader respectively; then modify the broadcast name of the bootloader program to generate a ZIP and use DFU to upgrade. The file transfer is completed, but the device has been restarting;

Hi,

It might be the softdevice is incompatible. Did you use the secure_dfu_ble_s140_pca10056_debug.hex under <nRF5_SDK>\examples\dfu\bootloader_secure_ble\hex?
