That is a bit strange.

[quote user="Yogesh Sarode"]Erase all also tried but did't worked[/quote]

So it is not allowing you to due to readback protection? Could you provide me this log? Are getting the same response if you run Erase&Write?

Are you getting any errors if you run "nrfjprog --recover" from commandline?

And what JLink version are you using again ("nrfjprog -v" in commandline)

Ah my mistake I meant erase-all. Reset is essentially just a power cycle. Does that help?

RE: nRF52 DK is not getting connected to programmer software.

Yogesh Sarode — Fri, 16 Dec 2022 10:22:48 GMT

Yes,I tried to reset it but the issue remains same.

RE: nRF52 DK is not getting connected to programmer software.

Elfving — Fri, 16 Dec 2022 09:49:57 GMT

Sounds like the device readback protection. Could you try resetting the device first?

Yes,I already tried to flash the Minew chip but it shows device is protected.

We are seeing it as not working because as soon as we connect the tag connect cable to Debug out connector of DK.The programmer device list shows JLINK and if we disconnect tag connect cable from debug out connector,programmer device list shows nRF52DK.

It might be your JLink version or the version of nRF Connect for Desktop that is different from what I have on my end, but it isn't necessarily more odd than that. It would make sense to distinguish between programming the SoC on the DK and programming the Minew chip using the DK, and the connection showing up as JLink sounds like a good way of doing so. We could look through the release notes of the versions you have of JLink and nRF Connect for Desktop, though lets see if its even a problem first:

Could you try flashing something to the Minew chip?

We are using MS50SFA-1Y10AIR Minew chip.

We have not shorted anything on DK.

We have also tried the connections suggested by you on P20. but here also if we short VDD and VTG,Programmer device list shows JLINK and if we open the VDD and VTG programmer device list shows nRF52DK.

Elfving — Thu, 15 Dec 2022 09:11:22 GMT

I see, that is a bit odd but I don't think that is necessarily any symptom of an issue on the DK.

[quote user="Elfving"]

What SoC is on the Minew chip?

How are you seeing it not working? Have you shorted anything on the DK previously?

Could you answer these questions?

Yes the flashing the SoC on the DK is working.I tried the hex file and LED1 is blinking.

Also the thing I observed that LED2 is contineously glowing but with very low intensity (Dimmed).

Elfving — Thu, 15 Dec 2022 08:23:00 GMT

How are you seeing it not working? Have you shorted anything on the DK previously?

Does flashing the SoC on the DK itself work?

You could for instance try this hex file right here, which should make LED1 blink.devzone.nordicsemi.com/.../zephyr_5F00_blinky.hex

What SoC is on the Minew chip?

Find the attached photograph of the DK. We are using PCA10040 3.0.0 version. Flashing to the Minew chip is not working. I strongly think that there may be something wrong with the DK. We are trying to program the Minew chip using tag connect cable as it was not working so we used the connections from P20 as suggested by you.

RE: nRF52 DK is not getting connected to programmer software.

Elfving — Wed, 14 Dec 2022 12:34:56 GMT

Hmm I wouldn't necessarily say so. What DK version are you using? Is the flashing working?

Are you programming it using SWD?

RE: nRF52 DK is not getting connected to programmer software.

Yogesh Sarode — Wed, 14 Dec 2022 08:56:19 GMT

One thing here I would like to mention that if we open the pins VDD amd VTG then device list shows nRF52DK and if we short it as shown in above figure then device list shows JLINK. Is that means there is something wrong with DK?

RE: nRF52 DK is not getting connected to programmer software.

Elfving — Wed, 14 Dec 2022 08:52:58 GMT

Then it seems to me as if things are functioning the way they should. The only "problem" is that device readback protection is being enabled after flashing, which is the default behavior now.

Is what you are flashing to the device functioning as you would expect it to?

RE: nRF52 DK is not getting connected to programmer software.

Yogesh Sarode — Wed, 14 Dec 2022 05:55:18 GMT

We tried the suggested method of wiring and observed that now there is no warning or error coming.

But as soon as we connect and open the nrf52dk device it does not show the device memory(Minew). and shows a message the device is protected.

If we try to erase the Minew,it erases device and the message shows the Resetting device completed.

Then if we try to erase and write the hex file then it shows "Device is loaded and ready for further operation"

And below that it shows "Skipped reading,Since at least one core has app readback protection"

Log file and screenshot is attached for your reference.

I see, I just wanted to make sure that you are not referring to the connectors which I've circled in the illustration below, they are routed to program the interface chip of the DK. As long as you use the debug out port on DK you should be fine. Or alternatively you could use the other setup I've outlined below.

So with the Debug Out port connected to the Minew chip, and the DK powered on, how is it looking in the nRF Programmer?

It is preferable to keep the conversation here, so that everything is neatly organized for anyone wanting to look over the conversation and pitch in.

Yogesh Sarode — Mon, 12 Dec 2022 04:12:35 GMT

The MINEW module is just a PCB with a nRF IC on it and the tag-connect connector is just a cable with a special tip to flash various microcontrollers.The tag-connect connector follows the ARM Cortex connector layout that is also used by NRF on the nRF52-DK.

Also We are using the debug protocol that suggested by you.

By using tag connect connector we can program either SWD or J-TAG interfaces.

Can we discuss the issue over phone? or have zoom meeting?

I am not really seeing the problem with this, nor why you are trying to to use the tag connector. Is the documentation of it stating that you should use tag connector?

What Minew chip are you using?

After looking a bit at a Minew chip overview, it looks like you might have to use SWD.

We want to program Minew board not the DK. If we connect the tag connect connector to DK and SWITCHED it ON then the programmer device list shows J Link and not nRF52DK.

Can you suggest any alternate programmer or flash tool?

RE: nRF52 DK is not getting connected to programmer software.

Elfving — Thu, 08 Dec 2022 10:12:27 GMT

The tag connector on the DK is for programming the debugging chip on the DK itself, so I don't think we need to explore that route.

In order to program the DK you can use the usb, and if you want to use the DK to program you Minew board you can either use SWD or the 10pin Jtag debug port. I think you will prefer the latter.

[quote user="Yogesh Sarode"]But still I am facing the same issue.[/quote][quote user="Yogesh Sarode"]And if we remove the tag connect connector from Dev Kit and SWITCHED it ON, the programmer software device list shows nRF52DK.[/quote]

I am not exactly sure how you are facing the same issue. Are you getting the error you saw in this previous reply of yours:

[quote user="Yogesh Sarode"]If I keep the DK turned ON and disconnect the tag connector then nothing happen but if I select the Jlink device,the name gets changed to nRF52DK and log shows unsupported device.[/quote]

Yogesh Sarode — Thu, 08 Dec 2022 09:40:27 GMT

I have arrange Window 10 Pro system and installed nRF connect for desktop and tried to load the hex file.

But still I am facing the same issue.

If we connect the tag connect connector to Dev Kit and SWITCHED it ON ,programmer software device list shows JLink.

And if we remove the tag connect connector from Dev Kit and SWITCHED it ON, the programmer software device list shows nRF52DK.

And the command nrfjprog is directly executed.

I definitely see how this can be confusing, and I am sorry about that.

I believe this document mainly explains how to use nRF 5 SDK and building it using SES, for which you would need either the 51 or 52 series, and atleast a Windows 8. However you can of course use our new nRF Connect SDK (NCS) instead, which works for the 52,53 and 91 series. The nRF Connect SDK is also recommended for new development. (So be aware that you can use NCS with your nRF52DK).

The tools in nRF Connect for Desktop such as the Programmer, is only supported on the maintained versions of Windows (ie. Windows 10 and above). The Programmer is listed as a tool on your document as you can still use the Programmer along with the nRF 5 SDK, but I believe you need to use a maintained version of Windows for it to work.

I am still not sure exactly why you cant find the path to nrfjprog, that should still work in Windows 8. Though if your main issue is getting the Programmer to work, then I would in any case recommend you to update to Windows 10. I am not sure if upgrading to Windows 10 fixes everything, but it might.

Yogesh Sarode — Thu, 08 Dec 2022 03:23:35 GMT

Yes, We are using windows 8. As per atttached document Windows 8 or 10 is the minimum requirement to operate Nrf52DK,so we have used Windows 8.

Shall we need to upgrade it with Windows 10?devzone.nordicsemi.com/.../getting_5F00_started_5F00_nRF5SDK_5F00_ses.pdf

RE: nRF52 DK is not getting connected to programmer software.

Elfving — Wed, 07 Dec 2022 12:03:11 GMT

Our tools are only supported on Windows versions that Microsoft supports, which does not count for Windows 8 anymore as of 2016.
