RECOVER_FAILED while tring to program NRF52840 using nrf programmer.

[Mahmoud Tayee]

Hello there,

I'm facing this issue(check the attached image) while tring to "Erase All" which indicates that it's protected that's why it failed to recover.

I searched for a solution, and found some suggestions to use the command "nrfjprog.exe -f nrf52 --recover --log", so I ran it and the logs are provided for it(check the attached .log file).

(The error on cmd tells that the used family is wrong, but it's right as you even can check the detected family with nrf programmer).

These are the used versions of nrfprog.exe:

and BTW I tried recovering using nRFgo Studio but didn't work also.

Hi,

 

Could you share the chip markings of the device you're trying to program?

Should be something like:

N52832

QFAAB0

2121AA

 

Kind regards,

Håkon

[Mahmoud Tayee]

Hi Håkon,

Here are the chip markings:

N52840

Q1AAF0

2322AQ

Best regards,

Mahmoud.

[Håkon Alseth]

Hi Mahmoud,

 

Thank you for providing the chip markings. You have a newer revision 3 nRF52832 device.

Based on your logs, the debugger is able to connect partially, meaning that it is able to communicate over the SWD.

Could this be an issue with the SWD speed?

Could you try to vary the speed, using the -c switch to nrfjprog?

Example: nrfjprog --recover -f nrf52 -c 125

 

This will set the SWD speed to 125 kHz.

 

Kind regards,

Håkon

[Mahmoud Tayee]

Hello Håkon,

I want to express my gratitude for your assistance.

Upon troubleshooting, it became apparent that the issue stemmed from an unsuitable power source for the Nordic chip. After implementing an alternative power supply method, the chip operated smoothly.

Thank you once again for your support.

Best regards, Mahmoud

[Håkon Alseth]

Hi Mahmoud,

 

Always happy to help out. Thank you for updating the case with the root-cause of the problem, this is highly appreciated!

I'm very glad to hear that you found a solution to the problem.

 

Hope you have a wonderful day!

 

Kind regards,

Håkon
