Corrupt data detected, please check connection to PPK.

[SM_]

Hi,

I am using the nrf52 DK with the PPK board.

nRF Connect Desktop ver:3.12.0 and power profiler app ver:3.4.5

my Power Profiler Kit on nRF52 DK stops recording every 3min with the error message "Corrupt data detected, please check connection to PPK."

why this error occurs? why does it time out after every 3 min?  how to increase the time period because I have to monitor the application continuously. 

Please help me with this.

Please check the below-attached log file.

Hi,

There are a few other reports of getting this error (like this thread), but I have not found any that match your exact description. One thing comes to mind, though. There is a known issue with data via the USB-UART interface on the onboard debugger if that has the mass storage device enabled (which is default). Can you disable that and see if it helps? To do that, use the command "MSDDisable" from J-Link Commander.

Hi Einar,

Thanks for the reply.

As per your suggestion, I have installed and tried to use the J-Link commander. 

I am not familiar with it. 

Is there any link for how to use it? (i.e. how to connect nRF52 DK with J-Link commander) or getting started guide. if any please share.

I am unable to connect the nRF52 DK to the J-link commander.

I am using the Windows 10 pc.

[Einar Thorsrud]

Hi,

You can use it like this:

1. Open J-Link Commander. This is a command line tool
2. Type the command "connect" and press the enter key
3. Now Type "S" to select SWD
4. Now just press enter to use the default interface speed
5. Type the command "MSDDisable" and press the enter key.

Here is the whole sequence when I did it:

This is a common fix for USB-UART communication issues via the SWD debugger, so this should be the first thing to test. However, I am not sure this will fix the issue you are seeing, so if this does not help we will need to look further into the issue.

Hi Einar,

I have Disabled the MSD via j-Link Commander but the issue is remains. it still stops after 3-sec interval

[Einar Thorsrud]

I do not know the root cause yet, but the maintainers are aware of it and will look into it. However, this issue is significantly improved if you downgrade the J-Link firmware on the DK to v6.80 of J-Link. With that, we see that you get the error after approximately 36 minutes of sampling. That is unfortunately the best workaround I have at this point in time. You can refer to this thread for how to downgrade the J-Link firmware.

[jzumaeta]

Hi Einar,

Any news about that? I'm presenting the same issue.

[Einar Thorsrud]

There was an issue with the performance of the J-Link firmware. This has been improved in v7.80c which was included in nRF Command Line Tools 10.18.0. So this issue should be resolved if you update to the latest version.
