PROCESSOR-SDK-AM62X: Regarding Main MCAN0 issue

Part Number: PROCESSOR-SDK-AM62X

Hi TI Team,

I read below link and performed same step in am625-sk EVM Revision 3.

https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/08_05_00_21/exports/docs/linux/How_to_Guides/Target/How_to_test_MCAN_on_AM62x.html#mcan-on-am62x

=> setenv name_overlays k3-am625-sk-mcan.dtbo
=> boot

I am able to get can0 port.

root@am62xx-evm:~# ifconfig can0
can0: flags=129<UP,NOARP> mtu 16 metric 1
unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 10 (UNSPEC)
RX packets 5 bytes 40 (40.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device interrupt 42

But the issue is, When I probe the pin C15 (MCAN0_TX) of am6254 SK EVM  on the oscilloscope, I couldn't see any transactions on this signal and It remains at 3.3V only.  Can you please suggest what may be the reason behind of this?

Thanks,

Maulik
