Tool/software:
Hi TI experts,i noticed the weird thing
if the CAN Boot ROM jump the Flash entry point due to coming of invalid key
from CAN Bus,the program on the flash works different than i expected.
My board TMS320F28388D. 20 MHz XTAL used.
My program resides the flash area and continuosly send CAN Message with 500 kbits.
I began contiunosly send ID:0x1 DATA:11 11 100 kbits over PCAN Device and then i power up the board with proper configuration for CAN Boot settings
(S2 Switch: POS1->ON POS2->OFF)
But my flash program send the data with 53.05 kbits speed.
Start bit: 1 bit
Arbitration field (29-bit identifier + SRR + IDE + RTR): 32 bits
Control field (DLC): 6 bits
Data field: 32 bits (4 bytes of data)
CRC field: 16 bits
ACK field: 2 bits
End of frame: 7 bits
Inter-frame space: 3 bits
1+32+6+32+16+2+7+3=99 bits
Baud Rate = (99 bits)/(0.00176 seconds) = 56.250 bps
Also i try to listen CAN Line with 53.05 kbits 75.9 Sample Point the PCAN. After incoming of the 16 message the bord
stop the send message.?
What causes the baud rate changing and stop the CAN message sending?
This is the 16th CAN message
