AWR1843BOOST: AWR1843 can-fd receives unregistered ID to crash

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: SYSBIOS, AWR1642

Recently debugging can-fd, in the canfd callback function, if the received ID is not registered in CANFD_createMsgObject, it will crash directly in CANFD_getData. If the frame ID received by canfd is registered, it will not die.The printed information is as follows:

Exception occurred in ThreadType_Hwi.
Hwi handle: 0x0.

Hi,

Can you please tell what application you are using? Is it the CNAFD driver application or have you integrated the CANFD driver into your application code?

Hi，

I used CCS to test canfd driver application, and I set the frame mode of canfd to CLASSIC.

Hello!

Recently, I tested xwr1642 and found that if using sdk3.1 or sdk3.3 to test canfd, the unregistered ID received by the chip would also crash.However, if the 1642 canfd function is tested using sdk2.1, the chip will not crash if it receives an unregistered ID.

Comparing the source code of canfd driver of several versions of SDK, it is found that there are many differences between sdk2.1 and sdk3.1. Does this mean that the above version of sdk3.1 and canfd driver have bugs?

Hi,

For the AWR1642, SDK version 2.1LTS (Long term support) is the recommended SDK.

Hello,

Now,I must use SDK3.0,because there is no 18xx.lib in SDK2.0.So how can i solve the problem the same with him. "debugging can-fd, in the canfd callback function, if the received ID is not registered in CANFD_createMsgObject, it will crash directly in CANFD_getData. If the frame ID received by canfd is registered, it will not die."

Hello, you can transfer sdk2.0 canfd source code to sdk3.0, a little modification, recompile the code.

Hello,

Thanks for your reply.I found the reason,I just set the configuration of MCAN filters,and MCAN works well!Thanks!
