Critical Issue: nRF52-DK, PCA10040 3.0.0 2022.14. Programmer v3.0.3 can not erase and Keil can not identify board and J-LINK Interface.

Dear Nordic support team,

I bought 3 piece of nRF52-DK from MOUSER, 1 piece of nRF52-DK version is 2.1.0 , and another 2 piece version is 3.0.0. 

nRF52-DK version 2.1.0, Programmer and Keil test ok.

nRF52 DK, PCA10040 3.0.0 2022.14. Programmer v3.0.3 can not erase and identify board, why?

Keil5 MDK v5.25.2.0, Debug -> Cannot find any J-LINK ??

Thanks,

Lishen

Hi

Okay, thank you for sharing. From the log, the procedures all seem to finish correctly as there are no errors, and you can see that app protect is enabled as you can see here:

2022-07-18T07:01:28.896Z INFO Readback protection status: NRFDL_PROTECTION_STATUS_ALL
2022-07-18T07:01:28.900Z INFO Parse memory regions for Application core

2022-07-18T07:01:28.908Z INFO Skipped reading, since at least one core has app readback protection

You can see that the firmware is written successfully here:

Next, the reason this is "UNKNOWN" I think is because the Programmer app hasn't been updated to recognize rev. 3.0.0 of the nRF52 DKs. I will contact the developers to confirm this and get back to you with an update.

Best regards,

Simon

Good news,

I download J-link new software manually from SEGGER website, and Keil 5 identify J-LINK OB now.

So I found that Programmer v3.0.3 will always lock nRF52832.  But nRFgo Studio lock or unlock selection by User define.

Thanks,
