Please verify the picture for the Baud rate of the Both the Boards
Hi Saravanan,
as explained before, the aim of the project for Pictus Discovery that I shared before is to send some CAN packets through the Pictus CAN transceiver to another board (based on another PowerPC device of the same Pictus family with the same CAN low level driver) that receives the CAN packets from Pictus, converts them in serial packets and transfers them via serial to the host. On the host we have a tool that shows the packets received via serial. In this way we can control the CAN packets sent by the Pictus directly on the host.
Now, the firmware on the second board that receives the CAN packets from the Pictus Discovery uses the same CAN low level driver used by the Pictus to trasmit the CAN packets. Since the baudrate of the CAN on Pictus Discovery is 1M, the same baudrate is configured also on this second board (please, see the configuration in attachment).
void flexcan1000_Fifo_RX(CANDriver *canp, CANRxFrame crfp) {
data_send(crfp);
(void) canp;
}
void data_send(CANRxFrame crfp) {
uint8_t buffer[18];
uint8_t i;
for (i=0;i<18;i++){
buffer[i] = 0x00;
}
*((uint16_t *)buffer) = crfp.TIME;
buffer[2] = crfp.LENGTH;
buffer[3] = crfp.RTR;
buffer[4] = crfp.TYPE;
//buffer += 5;
*((uint32_t *)&buffer[5]) = crfp.ID;
*((uint32_t *)&buffer[9]) = crfp.data32[0];
*((uint32_t *)&buffer[13]) = crfp.data32[1];
buffer[17] = 0xA4;
sd_lld_write(&SD1, buffer, 18);
}
int main(void) {
/* Initialization of all the imported components in the order specified in
the application wizard. The function is generated automatically.*/
componentsInit();
/* Enable Interrupts */
irqIsrEnable();
/* Start Serial Driver */
sd_lld_start(&SD1, NULL);
/* Start CAN Driver */
can_lld_start(&CAND1, &can_config_flexcan1000);
/* Application main loop.*/
for (;;) {
}
}where flexcan1000_Fifo_RX is the RX callback of the CAN low level driver used to receive the packets from the Pictus Discovery.
Finally, the CAN low level driver used on the second board has been a little bit patched to receive all the packets sent by the Pictus. You can find it in attachment.

Luigi
