Please help me check if the schematic diagram is correct？Is there anything else that is problematic or needs to be changed?
According to your previous suggestions, we have made modifications and the specific description is as follows:
1. Vsup voltage range is 6~24V. I don't see how much voltage is connected in the circuit, so please note here. Additionally, only one bypass capacitor is used for the supply voltage in the circuit. It is recommended to refer to the circuit in the EVM user's guide.
---The voltage is 12V, coming from the battery voltage;
2.The voltage of Vio can be 3.3V or 5V.
---Adjust the VIO voltage to 3.3V;
3. Many parts of the circuit cannot be seen. For those connected to the Soc terminal, 8 (nINT) and 9 (GPO2) are open drain outputs, and the pull-up resistance needs to be pulled up to Vio. The pull-up resistance range can be between 2Kohm and 10kohm.
----Pins 8 and 9 have been pulled up to VIO; The part connected to the platform has undergone a level conversion from 1.8V to 3.3V;
4. The resistance values R3 and R4 of the CAN and CANL output terminals are 60ohm matching resistors, and the value of C2 can be 4700pF.
---Revised as suggested;
5. I think the load capacitance of the crystal oscillator is 22pF, and combined with the Spec. of the crystal oscillator, it should comply with the load capacitance of the crystal oscillator. If the vibration cannot start normally, you can refer to the following application manual on crystal oscillator selection and design requirements: www.ti.com.cn/.../slla549.pdf
---The load capacitance of the crystal oscillator has been adjusted according to the crystal oscillator specifications;
