Correct, this should work the same way.

Great thanks, much appreciated!

Hi Jonathan,

Looks we got it working following your latest suggestion.

Broken nRF7002-DK now is powered via Arduino connectors since I have build a custom shield there to interface with my WIZcube I/O boards

So the procedure is:

1 - Power the nRF7002-DK first

2 - Then power the nRF9160 "programmer"

3 - Open VS code reports that nRF9160-DK is connected but reports chip nRF5340 (that is on the nRF7002-DK. Proceed with programming, flashing OK and application is working.

In Desk top programmer same results. This is OK

Project image looks complicated but it is not. While waiting for the right cable I had to do a "home made" programmer cable from old staff. I was unable to source it locally.

The nice thing is that I am able to program the nRF7002-DK using nRF9260-DK

I will have that as a reference creating step by step directions to my contest project. This experience may will be interested to others.

I imagine I can program Thingy:53 (or ant Thingy) in VS code as well using the same method.

Job Done. Consider it as answered

Thank you Jonathan

Regards

Vasilis

Hi Jonathan

Yes I am still stacked. In fact am in kind of panic concerning the contest dead line. Time is very limited now and I am troubling to move forward.

Anyway I will do that and report back

Still stuck?

Try to only power the nRF7002DK with two jumper cables, one for VDD and one for GND. Then use the 10pin connector cable.

If in need of a infographic i can provide one later.

Jonathan

Hi Jonathan

Within VS trying to recover I got the message:

Error recovering device. see output tab

[11/21/2023, 1:06:31 PM] Unable to resolve configuration with compilerPath "/home/vorrias/ncs/toolchains/1f9b40e71a/opt/zephyr-sdk/arm-zephyr-eabi/bin/arm-zephyr-eabi-gcc". Using "/usr/bin/clang-14" instead.

Within nRF connect for Desktop programmer I have the erase dimmed

NOTE: I did not change anything on my DKs.

I see your notes afterwords.

Anyway I am reading your last post to see your directions

Hi Vasilis, looks like approtect is on, try to run a recover first.

You can do this with either running nrfjprog --recover in the terminal or click on the recover option for connected devices

Or you can use the nRF connect for Desktop programmer application by clicking on the Erase all button

Jonathan

[quote user=""]eading Nordic documentation we see that another DK can be used as a JTAG programmer.[/quote]

Correct! For the nRF7002DK to be programmed you need a programmer that is able to program the onboard SoC. Since the nRF7002DK uses a nRF5340 you will need a DK that has a onboard programmer that will support it.

To be on the safe side you should either be using a nRF9160DK or a nRF5340DK, these two will be able to program everything we have including nRF5340 and nRF9160's.

So since it seams that you have a nRF9160 available you should be fine.

There are a few ways to program the "external board"(your broken nRF7002DK) so the simplest option according to most is to use a flat ribbon cable. These are easy to use and there is no extra fumbling with cables.

First and simplest option(if you have a flat ribbon cable)

Connect the cable to P19 (Debug out) on the DK that you use as your programmer(nRF9160DK or nRF5340DK) then connect the other end of the flat ribbon cable to P18 (Debug in) on the nRF7002DK.

So from here:

To here:

Second option is to use some cables and connect from P20 on the programmer DK to the external boards P25 trace pads.
From here:
The image above is from a nRF5340DK but its the same on the nRF9160 DK. And the custom board will be your broken 7002DK

To here:

Its a bit more tricky and you will have to solder on to the pads. GND and VDD also needs to be connected but that can be done to any of the corresponding P1 female headers

There are other options as well here for method two, but feel free to ask and I will guide you.

Jonathan

Hi,

The last hours I did some progress but was unable to program the target (nRF7002-DK). I got this error in VS code:

[error] [ Client] - Encountered error -11: Command erase_file executed for 2075 milliseconds with result -11
[error] [ nRF53] - Failed while detecting device memory block protection status!

What was done so far:

1 - Connect the two boards with JTAG cable. nRF9150-DK OUT to nRF7002-DK IN

2 - Leave the Voltage selector on nRF9260-DK in 1V8 position. When in 3V board is dead.

3 - Power the nRF7002-DK via nRF5340 USB port

4 - Plug the USB cable on the debugger port (nRF9160-DK)

at this point I see a JLINK device discovered. If JTAG flat cable is not connecting the two boards I see that nRF9160 is discovered.

I suppose that means that nrF9160-DK works OK as a JTAG programmer when the tow boards are connected via flat cable.

It looks that I can not start programming the nRF7002-DK which now runs the Light Bulb Matter program.

If I can program it with a blink program that will be a good start.

What am I doing wrong?

Thanks for any extra help
