iMxRT1021 hardfault in IAR C++ library

[ChengGu]

To whom it may concern,

 I am using iMxRT1021 dev board, my IDE is IAR, my project use many C++ object such as map etc. sometime, my code get hardfault while running in these IAR C++ library codes, or my map objects are crashed in the middle. could this relate with iMxRT cache setting? any suggestion on how to debug such issue? thanks a lot.

Best

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
Firstly, I'd like to know whether you locate the code line that invokes the hardfault interrupt. next, I was wondering if you can introduce these C++ libraries briefly.
Have a great day,
TIC
