Thanks Vidar, that worked. I think it would be helpful for others if you updated your documentation with regard to this issue.

Hi,

OK, thanks for confirming. This board has the new revision of the 52832 (IN142 Informational Notice v1.1) where readback protection is enabled by default.

My suggestion was that you used nrfjprog from the nRF command line tools package to unlock the chip first. The Bluetooth Low Energy v3.0.0 should be able to program the connectivity FW onto your board after the readback protection has been disabled.

Hi Vidor,

The label reads:

PCA10040

2.2 0

2022.3

682337947

There isn't a debug console that I can see in the Bluetooth Low Energy v3.0.0 application, are you referring to the one in VS Code please?

From the log it seems like this is an issue with the debug readback protection being enabled, not with the VCOM interface.

You can run the following command from the debug terminal to unlock the chip:

$ nrfjprog --recover

What version of the DK do you have? You can find the version number printed on the white sticker on top of the interface chip.

Did you remember to power-cycle the board after running the MSDDisable command. This is necessary for the change to take effect.

Thanks Vidar, I've done that:

In macOS Terminal, navigate to folder with JLinkExe:

alwalker@Als-MBP-2 JLink_V758b % JLinkExe

Then type:

J-Link>MSDDisable

Probe configured successfully.

J-Link>

However this doesn't appear to fix the issue, log file attached.

Hi,

Please try to run "JLinkExe" from the terminal. This is the name of the Jlink commander executable on macOS and Linux.

Best regards,

Vidar
