AWR1642: awr1642 canFd bufAddr

AlbertYip

Part Number: AWR1642

hello, everyone:

I am debuging canFd module with SDK3.0.0.8 and I have a issue:

I configure the fifo0Size = 64 and fifo1Size = 64,and others parameters in createMsgObject are showed in the following picture

I create a rxHandle with id = 0x75, and it can receive normally a message(11 bits) if id of the message is 0x75, but CPU stops when other message occuring on the CAN bus.

I found that when the message(id != 0x75) occuring, the program can enter the RX ISR, and execute the callback function. It will stop in the getData function. I have tried the following methods:

1. cancle the createMsgObject, the issue can not be resolved.

2.set fifo0Size = 0 and fifo1Size = 0,the issue can be resolved.

I receive the message with the dedicated buffer, why the fifoSize effects the result?

there is not rxMsgObject(i cancle thecreateMsgObject), why it can enter rx ISR? And why it stops?

I have looked at the canfd driver unit tested provided. The parameters in my project is referenced with the unit tested but the 'fifo0Size' and 'fifo1Size'

Hello ,
The FIFO configurations you mentioned are the default configuration in our driver .We have tested the CANFD driver with multiple message objects for both Tx and Rx and found it to be working .

Please post any changes that you have done in the code to review and check if there are any issues in your changes.

Thanks,
Raghu
