Hi,

[quote user="Zhongsan"]and pin1 of P19 is not connected anything[/quote]

I think that pin should be connected to VDD on the target. What voltage do you measure on pin 1 of P19 header?

Have you soldered a 10 pin J-tag header on the back of the Dongle? Which pins are you using to connect to the dongle from the DK?

Hi, Jared

VDD on nRF5340 is 3.0V, at SB47, and pin1 of P19 is not connected anything

thanks

The nRF5340 DK documentation states:

The voltage supported by external debugging/programming is VDD voltage. Normally, this is 3 V when running from USB. But if the onboard nRF5340 SoC is supplied from either USB or lithium-ion (Li-ion) and the nRF power source switch (SW9) is in either Li-Po or USB position, then the VDD can be set by the nRF5340 firmware. Make sure the voltage level of the external board matches the VDD of the nRF5340 DK.

Can you verify that the VDD on the nRF5340 and the Dongle is the same?

and the power is from nrf52840dongle itself

1. i want to debug the nrf52840, not just programme it

2.the voltage is 3.3v

Hi,

You can use nrfjprog --program <HEX> --sectorerase . This will erase only the programmed area in the flash.
What voltage do you measure on the VDD pin on the Dongle when you try to program it?
