/* Optional: Disconnect from the USB host. */ CyU3PConnectState (CyFalse, CyTrue); /* Required: Make sure that any serial peripheral modules are stopped at this point. */ CyU3PDebugDeInit (); CyU3PUartDeInit (); CyU3PGpioDeInit (); /* Store the firmware entry address at the restart location. */ *((uint32_t *)0x40000000) = (uint32_t)(&CyU3PFirmwareEntry); CyU3PDeviceReset (CyTrue);
