52DK Download failed with VS code

It didn't fail. It says "flashed successfully". This is only a warning.

Hi,

What version of nrfjprog and JLINK do you have? To find this, run nrfjprog -v.

Best regards,

Marte

Hi,

nrfjprog version is 10.15.4

Jlink version is 7.65a

Please see the figure

Hi, 

Can you try recovering the device by running nrfjprog --recover before you program it?

Best regards,

Marte

Hi Marte,

The result is still a failure.

I had tried to install the lower version of nrfjprog and download,it's still a failure too.

Best regards.

Hi Marte,

I'm find the issue from this website

https://devzone.nordicsemi.com/f/nordic-q-a/46809/nrfjprog-write-verify-failed

The root cause is too high of clock of jlink,nrfjprog should add a parameter -c 125~1000,and i'm test this is ok from command line,could this parameter be configured to the vs code flash button?

Best regards.
