RDSR2 fails

[meraki]

The following errors come up suddenly. 
I'm utilising the jlink of nrf5340 dk to flash my custom board. Using nrf sdk v2.6.1

Hi

When you say it suddenly came up with the errors, did it work before, if so what changes have you done to your application? 

Is this a custom application or one of our samples?
