Dears,
Currently, when working with the nRF52833dk, I found some weird behavior.
I tried to run the blink example in nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\ble_app_blinky\pca10040\s132.
I flash it via diferrent way:
1. First SoftDevice via nRFgo Studio, then Application via nRFgo Studio
2, First SoftDevice via nRFgo Studio, then Application via keil C
3, Flash the SoftDevice and the Appication via nRF connect Programmer v3.0.4
Note that I already erase all the chip before every tries.
Only when I flash the first way - using nRFgo Studio for both SoftDevice and Application - the soc run.
Other ways, the soc cannot run.
By reading back the SOC, I found no diffrent for both three ways of flashing.

I attached the Application hex file nrf52832_xxaa.hex and the SoftDevice file s132_nrf52_6.1.1_softdevice.hex
1220.s132_nrf52_6.1.1_softdevice.hex
My questions are:
1. What is wrong with the 2nd and 3rd way of flashing?
2. How to solve it?
Please awswer, I am trying to run the /dfu/secure_bootloader but it cannot be flash via nRFgo Studio. And when I test with the blink example. This issue happen.
Best regards.
