Tool/software:

Hello,

My project could only debug normally under the optimization level 0.When the optimization is set to level 1 or higher,instructions for operating 64-bit registers will appear in the generated assembly,my project will go wrong when execute the instructions for operating 64-bit XD registers.

Thanks,

Zihao

    Hi Zihao,

    What do you mean by below :

    What exactly happens ? Can you monitor XRSn and see if the device resets ?

    What are you executing ? Do you have an NMI ISR setup for the CPU you are running it on ? Check the SDK example on how to setup the NMI ISR

    Thanks
