Hi, @yao_feng 

I received our internal team feedback as below:

The reported issue is a regression issue and it is fixed already.

We have verified the changes on our local setup and it is working fine.

The release with the fixes will be available in Q2 (end of June). 

Please help to update this info to our end customer and request them to verify on the Q2 release.

Thanks.

Best regards,

Christine.

Hi, @NancyHuang 

We have standalone release completed and available on the nxp.com with secure sign in.

Can you please check if this link can be accessible to you for the Q2 release?

Below link is for 88W8987:
