CAN_WAKE Problem

Autonomous Machines Jetson & Embedded Systems Jetson TX2
#1

Hi

The CAN_WAKE on the developer kit (Pin 1, J26) when toggled between 0 and 3.3V,
do not cause the Jetson to exit from deep sleep mode.
(which was entered by sudo systemctl suspend)

I checked the related registers. Here are the result:

Pinmux register 0x0c303048 → value : 0x58
GPIO register 0x0c2f1c80 → value : 0x1

Jetpack version: 4.6.1

Any help would be appreciated.

Sorry for the late response, is this still an issue to support? Thanks

Hi

Yes

Although I can communicate through CAN port, the CAN_WAKE pin does not function properly.

Hi

I am waiting for a response

Thanks

Please check the software feature listed in the developer guide.

We don’t enable CAN wake on jetson as wake up source.

It means I should enable it in the Pinmux and reflash the jetson?

In the downloaded Pinmux file, the CAN_WAKE pin is set as a wake up source.

In ROW 221 of the Pinmux (CAN_WAKE pin), under Wake Pin column, “Yes” is selected by default.
