S32G-PROCEVB3-S Hands on FlexCAN

[Thinh]

Hello Supporter

I face problem when send/receive CAN message via CAN0: CAN is always busy as some topics mentioned, there is no tx and rx message.

I have follow below documentations to modify example "FlexCAN_Ip_Example_S32G399A_M7" to normal mode, send/receive message with CAN case/CANoe

- S32G-VNP-RDB3 Real-Time Driver Enablement Training Presentation

- S32G-PROCEVB3-S Schematics

Below is my change/configuration:

1. Enable PIN configuration: set up can tx/rx pin PC_12/PC_11

2. Change Clock for CAN:

3. Change config for FlexCAN0, add Siul2_Port

4. Update code, Init Port, change linker file

6. Build code successfully:

Please check am I wrong somewhere or any further step to do for success send/receive CAN

Hello @Thinh,

Thanks for contacting NXP support. Regarding your problem, please share the following details so that I may reproduce the issue on my side:

• S32 Design Studio version used
• RTD Version used
• Are you creating an IVT binary blob or are you running the project with the debugger?
• If possible please share the complete project you are using, you can use the private message feature of the community if you prefer not to send it in this public channel.
• How exactly are you checking the errors? For example oscilloscope or CAN-USB transceiver.
• Please share photos of the board to check the jumper configuration, in particular J155
  • 

Please share any other details that can help me narrow down the problem or reproduce it on my side.

Thanks in advance
