SPC574S CAN communication failed。

[wminx.1]

When I test CAN whether it can send data successfully。 I found it always ​failed. Now I use 100pin SPC574s. I have configured can tx PB0(18),PA15(17)pin. I test using SPC5Studio 6.00 version. please help me check my project. Thanks a lot.

Hello,

I suspect you have configured FlexRay output pins and not CAN pins.

Accordingly to board schematics [link] the pin to configure for CAN are:

• PA12 - RX
• PA13 - TX

Also:

• jumper JP11 must be in position 1-2

alternatively

• set JP11 in position 2-3
• configure PD4 as push-pull
• drive PD4 low state

Please note that, in SPC5Studio, CAN demo configurations are in External Loopback mode,

so. output is seen on CAN bus, but no external input is received.

Regards,

Giuseppe
