Hi, support team
I have an issue with CAN transmitting.
After configuring the chip by referring to "TCAN4551_UserGuide.pdf".
I'm able to config the MRAM address and store the CAN packet into the MRAM successfully.
However, when I config the chip into the normal mode and transmit, there is no transmission.
Findings:
1. Enter into normal mode, before transmit request:
1. Read address 0820h, return 0x000004A0
2. Read address 1044h, return 0x0000070F
3. Read address 1050h, return 0x00000000
2. Enter into normal mode, right after transmit request:
1. Read address 0820h, return 0x000004A0
2. Read address 1044h, return 0x0000077B
3. Read address 1050h, return 0x09800800
Questions:
1. Based on the datasheet, "Fail-Safe Mode" require to enable only CANSLNT will be set to 1. Is there any other factor that will set CANSLNT without enabling "Fail-Safe Mode"?
2. I did not configure the CAN timing. (using default settings). Will it cause this issue?
Regards,
John
