Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I'd like to know what modification you did in addition above change, further, did you test in debug mode?
Have a great day,
TIC

Hi,
Thanks for your reply.
Actually, I'm not sure the root cause, however, I think you'd better modify the below two options besides your previous modification.

Furthermore, the issue may be related to the on/off option of the PDRAM1.

Last, I'm curious why you run the code in the RAM to test low power mode.

Have a great day,
TIC
