hello.

In AM4378 ,I use dcan_app_frame_tx_rx example from am437x_sysbios_ind_sdk_2.0.0.2.

When I Initialize the DCAN message RAM, it can't complete.

So,i add some code before RAM Initialization,like wait a moment,reset DCAN,enable ram parity.Some times it woks,but most of times,it can't.

anyone can help me?Thanks a lot!

Could you please try the dcan example in the Processor SDK RTOS package for AM437x and see if you encounter the same problem?

I believe the ISDK version that you are working with had a problem with the dcan example and since been removed in v2.1.3.2.
The example is located at C:\ti\pdk_am437x_1_0_4\packages\ti\starterware\examples\dcan in the Processor SDK package.

The ISDK package will have some changes coming up as described here www.ti.com/.../sysbiossdk-ind-sitara, so I believe the issues you are seeing may be addressed in the new release.
