FlexCAN driver (on S32K3X4EVB-T172 EVB) can't access via PCAN

[Jireh]

Hi, Sirs,

Please help us as following, Thanks.

(1) Our Environment: 

• HW: S32K3X4EVB-T172
• S32K DS: 3.4
• sample code: FlexCAN on S32K344
• 
•  

(2) Pins config. :

• our config.
• 

• EVB user manual: PHY is TJA1443.
• 

(3) clock config. : 24MHz

(4) Peripherals config. : 

• FlexCAN: 

• Interrupt: 
• 

(5) main.c 

(6) result is NG : check PHY TJA1443 & connect with PCAN

• measured each pins of PHY
• 
• used PCAN to send package: 
•

Hi Jireh,

Could you send me the project which you have sent to Support, because I am trying compile but I can´t transmite and receive the information by the channels of CAN. I am trying to use the PCAN but I have problems too because I don´t receive any information. 

Thank you for all,

[Jireh]

thanks a lot, it was working~ (CAN FD)

then, I'm going to check what's the difference with FlexCAN example (CAN only).

Hi@Jireh

TJA1443 needs to do some configuration first.

please refer to this demo posted by Peter.

(the can transceiver on this demo is TJA1153, which is similar to TJA1143 I guess)

Hello, I tried this solution on T172 EVB. 

It works - nonworks (if reload ELF or reset board) - works (if reload ELF again)

Do you have the similar issue?
