Do the TK1 UART ports support waking up from sleep (LP0/LP1) when they receive a UART packet? How to set it up in Linux?
Only UART3_CTS_N support wake event, but it is not lined out on Jetson TK1.
OK. I’m not using Jetson, so I can get access to it. I’m guessing I’ll have to set it up as a standard GPIO Interrupt pin in the device tree?
I think this pin can program as GPIO pin to wake up the system, however that means it doesn’t matter with the UART. I believe there’s no way to wake up the system by UART receiving data.
