Hi,

There is no way for the user to change what the flash button in the VS Code extension does at the moment, so you will have to use nrfjprog to program your device if you need to change the debugger SWD clock speed. I can forward this as a feature request.

Best regards,

Marte

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.

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,

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

Best regards,

Marte

Hi,

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

Best regards,

Marte

Hi,

The target area needs to be erased. If not, --program will fail. You can erase the chip before programming, but the simplest option is to erase the chip as a part of the programming operation:

nrfjprog -f nrf52 --program zephyr.hex --chiperase --verify

You can also add --reset to the command above to make the device reset after flashing.

Best regards,

Marte

But the board is not running even power reset after download is completed.

Then i'm tried to copy the zephyr.hex to another directory and download by iar,it works fine.

I'm tried to download again by nrfjprog command,

The command is:nrfjprog --program zephyr.hex --verify --log

See the information as below

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