Not able to flash nRF5340 PDK anymore

[sethu]

Hey guys, 

All of a sudden, I'm not able to flash my nRF board anymore. I get the following message when I try to connect to the board using segger IDE.

And when I try west flash, I get the following:

As per that message, when I try "west flash --log", I get unknow command error.

Any help would be appreciated. 

Other info:

I'm pretty sure that it isn't a problem with the code I'm trying to flash or even anything on the PC because I have another one of the same board which works without any problem.

I tried both the solutions mentioned but still no luck, both gave me error as shown below:

Nrfjprog and the nrf connect had been updated prior to executing the commands.

[Amanda Hsieh]

Please try the latest version of the nRF-Command-Line-Tools. If it still cannot fix the issue, run the following commands, and provide the logs. 

 

nrfjprog.exe --coprocessor CP_NETWORK --recover --log NETWORK.log
nrfjprog.exe --coprocessor CP_APPLICATION --recover --log APPLICATION.log

Also, this was printed out on the command line for both commands:

ERROR: nrfjprog could not identify the target device. This may be due to an
ERROR: invalid family argument, a problem with your device, or nrfjprog may
ERROR: not yet support your device.
ERROR: Please check the family argument passed, or upgrade nrfjprog to a more
ERROR: recent version.

At this point, I think the chip is dead.

Hi, 

First of all, make sure the board is power cycled, the J-Link OB can sometimes lock up and cause the DK to be unresponsive. 

The error log looks like it is unable to detect the family of the device. Please run the following commands. That should skip the step that generated the error, and may allow succeeding. If it still cannot work, please provide the log with --log name.log in the command. Thanks. 

nrfjprog.exe --coprocessor CP_NETWORK --recover -f NRF53 
nrfjprog.exe --coprocessor CP_APPLICATION --recover -f NRF53

Now that I run the command, this is the only output from the log file for both cases. 

Also, the command gives an error saying the following:

ERROR: Argument provided has a wrong value. Memory access not aligned, value
ERROR: outside of range or similar.

thanks

[Amanda Hsieh]

Sorry for the mistake, it is "-f NRF53". I have modified the previous commands. Please try again.

Hey, 

No worries. I have done it again and both commands give almost the same output which has been attached below:

Hi Sethu, 

Could you try the latest version of nrfjprog v10.12.1?

Please let me know it can help or not. Thanks.

I have the same issue. However, updating nrfjprog to version v10.12.1 did not help. I am using Ubuntu 20.04.
