https://community.nxp.com/t5/MPC5xxx/MPC5777C/m-p/1354190#M19337 <P>Hi,</P> <P>code looks normal, I think. So which kind of message are you receiving? MBs are configured to receive std or ext ID 0, so is this message sent from other node?<BR />Do you see any error detected in module? See ECR, ESR1 register.</P> <P>BR, Petr</P> Tue, 12 Oct 2021 10:43:28 GMT PetrS 2021-10-12T10:43:28Z https://community.nxp.com/t5/MPC5xxx/MPC5777C/m-p/1353485#M19329 <P>Dear:</P><P>In the following program，I find CAN messages cannot be received through this driver. I don't know where the driver problem is. Through debugging in RAM, I found that IFLAG1 is not set.</P><P>respect</P> Mon, 11 Oct 2021 11:01:31 GMT https://community.nxp.com/t5/MPC5xxx/MPC5777C/m-p/1353485#M19329 PENGHAN 2021-10-11T11:01:31Z https://community.nxp.com/t5/MPC5xxx/MPC5777C/m-p/1354190#M19337 <P>Hi,</P> <P>code looks normal, I think.
