RE: Cannot Flash 5340DK

Can you measure the VDD_nRF' voltage on this pin:

It should be 3V.

Can you try is to supply the nRF5340 using the second USB connector in addition to the debugger USB connector. To do this you need to switch the power source to USB using switch SW9.

Thank you so much for your reply!

Yes, it is brand new, so that I'm sure the SB40 SB54 SB55 are connected. I have anther new board and it can be flashed successfully.

I have tried to use the NRF programmer but still cannot, below is the error information:

Error: Failed with exit code 1. Failed to device info one or more devices: * 1050041747: [jlink] Unable to fetch device-info, code: Generic. Message: Operation device-info failed, [jlink] Unable to fetch device-info.

Again I try to use the NCS to flash, the error shows:

I hope you could help me to figure out the problems:😀

Hi,

Are both the nRF5340DK new out of box, or have you used them previously?

If they are not new you should check if the solder bridge for current measurement(SB40) have been cut, if it is cut you need a jumper on P22.

The SWD interface may also have been disconencted from the onboard debugger, check if tSB54(SWDIO) and SB55(SWDCLK) have been cut.

Best regards,

Bendik
