SES project + Amazon freertos + LPC54018 : Coprocessor hardfault


I am using the project provided by Segger to run the amazon freertos on the LPC54018 with Embbedded studio.

I can compile the project cleanly, but when debugging, the program stops because of a UsageFault_Coprocessor and report it is stopped by vector catch.

It seems that the hard fault happens after the freertos scheduler start.

I'm not sure how to debug this fault. Do you have any idea of what may happen ?

Thank you,
