Error: DAP error while reading AIRCR

[SakSath]

Hi,

I am trying to connect to i.mx 1170EVK from Jlink and started facing this issue 

Error: DAP error while reading AIRCR

The issue has randomly popped up and I tried solutions like "unlocking kinetis" - but nothing worked.

I was able to connect to the board properly multiple times before this error popped up.

Also I have tried re booting the board using LPC scrypt.

Any solution / workaround is highly appreciated.

Thanks!

Hi @SakSath ,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
Firstly, I hope you can share the screenshot of the error, next, you can try the below trick to recover.
) Set the SW1 to Serial Downloader.
2) Power on the board, and debug the demo project.
3) After that, power off and recover the SW1 to the previous set, then power on again.
4) Give a debug again.
Have a great day,
TIC
