I used 2 LPC1769 to communicate.I connected CAN1 of 2 LPC1769 through 2 CAN tranceiver(TI SN65HVD251 IC CAN RXTX 5V). After receive only one message from LPC1769 no1, LPC1769 no2 jump to HardFault_Handler(void). I checked the ID and data of the first message, everything was ok! After released RX buffer in CAN_ISR_Rx1 function it jump to HardFault_Handler function.(I use CAN baudrate 125K).

Please help me!
