Ok, good!

For the one board that is failing, you might want to check that VDD is at the expected level. And maybe try to reflow the board if possible.(Could be some bad soldering or something that is causing issues.)

Yes. A custom board. For my other boards of this type the 10.17.3 version of nrfjprog seems to be working ok.

Thx again for your help.

Turns out that this was a possible problem with the SoC. With another one it seemed to go OK.

Ok, so you are just seeing this on one board. Is it a custom board or a DK ?

Thx. That was very helpful.

We are now trying to flash with nrfjprog version 10.17.3 external

First errors are:

```

[debug]: [SeggerBackend] - ---just_select_debug_port_register

[debug]: [SeggerBackend] - Select AP 255, DP Bank 0, AP Bank 255

[trace]: [ JLink] - JLINK_CORESIGHT_WriteAPDPReg(DP reg 0x02, 0x00000000)

[trace]: [ JLink] - - 0.473ms returns -1

[trace]: [ JLink] - JLINK_HasError()

[error]: [SeggerBackend] - JLinkARM.dll reported "-1", "An unknown error.".

```

Turns out that this was a possible problem with the SoC. With another one it seemed to go OK.

As to the error message that's not very helpful.

[quote user="paul_tanner"]Anyone know where the newly installed executable can be found?[/quote]

According to the document here,

After running the installer, the nRF Command Line Tools are ready for use. By default, they are installed in the following directories:

On Windows (64-bit): C:/Program Files/Nordic Semiconductor/nrf-command-line-tools/bin/
On Windows (32-bit): C:/Program Files (x86)/Nordic Semiconductor/nrf-command-line-tools/bin/
On Linux: /opt/
On macOS: /Applications/Nordic Semiconductor/

Thanks for that Sigurd

Yes. Although I downloaded the latest installer package, I got an older version when I ran it . I need to fix the simlink in /usr/local/bin.

However, try as I may I cannot locate where the installer has placed the updated version.

I went back to the Nordic page where the download link is given. Nothing on the precise destination other than allowing a choice of destination drive.

I'm reluctant to delete all versions in case I break something else.

Anyone know where the newly installed executable can be found?

Hi,

[quote user=""]nrfjprog version now 10.12.0[/quote]

This is quite an old version. Try downloading the latest version. As of today, v10.17.3 is the latest version.
