Hello,
We are trying to enable wake up function from UART1 but I don't know how to do that. After put imx6SL into sleep mode, it will wake up if we send data to uart1 pin.
We did below command execution but still no result
#echo enabled > /sys/class/tty/ttymxc1/power/wakeup
#echo enabled > /sys/bus/platform/drivers/imx-uart/2024000.serial/tty/ttymxc1/power/wakeup
Do you have any suggestion in this case?
Thanks

Hi Devi
please look at procedure described in sect.21.1.5 Unit Test
attached Linux Manual. One can use imx-test (unit test)
www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-test-5.7.tar.gz
and Demo Images on

Thank you for reply
In our custom board we are using kitkat 4.4.3 and we are able to wake up and send data to UART0 which is debug console. But UART1 is not working. UART1 is used for the GPRS in our custom board. In suspend mode if we send data through UART1 its not responding.
Do you have any suggestion in this case?
Thanks
