Hi,
i used keil to generate new project for usb device HID and FreeRtos and CMSIS in HIGH SPEED mode ( 0x1000 of stack and 0x1000 of heap to be sure ) .
I make a task to start the program with only USBD_Initialize( 0 ) and USBD_Connect( 0 ). The project works only one time on 10 test, normaly no sound of device connected on pc (ding dong ) or i receive a HardFalutHandler excpetion. I contattected other people with same part ( LPC4357 ) to generate same project, and they have the same problems.
Someone know where can be the problem ?
Sorry for my english !!
