Can wake

Autonomous Machines Jetson & Embedded Systems Jetson TX2

Hi

There is a post discussing a wake problem related to CAN_WAKE signal, and NVIDIA said in the last post that the wake from sleep using CAN_WAKE is not supported.

https://forums.developer.nvidia.com/t/jetson-tx2-doesnt-wake-up-from-gpio-pin-trigger/52146

On the other hand, it is explicitly mentioned in the Jetson TX2 product design guide that the CAN_WAKE pin can be used to exit from deep sleep.

Which is correct?
Any update on this?

Thanks.

hi alihaeri,

Yes, CAN wake as a GPIO pin is supported on TX2.
Can you check what is the pin configuration?
Read these registers:
Pinmux: 0x0c303048
GPIO: 0x0c2f1c80

you can use devmem tool to read these registers from linux userspace.
Let me know what value these are configured to?
This pin should be input from gpio and pinmux.
Also, make sure you are toggling on Pin1 of Expansion header.

Thanks,
Shubhi
