AddressSanitizer with RT1021 and MCUXpresso?

rshipman — Fri, 16 Apr 2021 11:36:40 GMT

Hi,

Can you tell me how I can get set up with the AddressSanitizer for the RT1021 in MCUXpresso please?

I have found the -fsanitize=address etc settings, but I don't know how or where to get the library it requires. (Otherwise I get lots of messages like "undefined reference to __ubsan_handle_pointer_overflow" etc.)

Also if I turn -fsanitize=address etc on for the C compiler, it does not compile. For example:

arm-none-eabi-gcc: error: unrecognized command line option '-fsanitize-address'; did you mean '-fsanitize=address'?
arm-none-eabi-gcc: error: unrecognized command line option '-fsanitize-pointer-compare'; did you mean '-fsanitize=pointer-compare'?

Any help much appreciated.

Hi Ronnie,

Unfortunately, we do not have an official way to set up AddressSanitizer in MCUXpresso IDE. Please check the community thread below that provides a more detailed explanation about this.
