llce_sample_app_pfe ETH2CAN problem

seeu — Thu, 13 Jul 2023 02:22:03 GMT

Hi,

I use llce_sample_app_pfe to run ETH2CAN can't work normally, Because I can't receive the CAN frame normally. But in this sample I can get the acf-can frame，whether this routine can only implement CAN2ETH, but not ETH2CAN?

Also, in data.dump debug_buff, there are some information Client's (1) RX queue is full. Frame dropped. Is this normal phenomenon?

Hi,

Can you let us know which RTD/LLCE/PFE version are you using? Also, are you using any NXP platforms? Or is this a custom board?

Please, let us know.

Hi,

Thanks for the information. Ther are 2 known-issues under the above mentioned LLCE v1.0.4 example. One is the ETH2CAN buffer configurations.

Have you done any modifications to the project?

The ETH2CAN buffer config change is the following:

Please, let us know.

Hi,

I chang the value from 72 to 73, now the frame drop problem were solved. But I can't still receive the can frame from ETH2CAN. Because I comment the CAN2ETH code, and use tcpreplay to send the ETH packet to PFE_MAC1(P3A connector)，and run the code， Logic analyzer can't receive CAN frame， and the variable rxIndicationCount=0 .

Hi,

Thanks for your feedback.

The recommended way of doing the ETH2CAN channel is to select the UDP packet being sent with the CAN2ETH feature then sending it back:

Is this what you are doing?

Please, let us know.

Hi,

I chang the value from 72 to 73, and re-open trace32 GUI, now it can run normally.But I don't know why I fail last time.
