hello to who it may concerned
I use my customized board, and configure the uart2
it can work normally
and i hope it can be the wakeup source for the low power mode.
i set the echo enabled > wakeup for ttymxc1
but it does not work
(if i set the ttymxc0,it can wake up the system)
i check the i.MX 6SLL Applications Processor Reference Manual
it seemed it can only work in the debug uart(ttymxc0)
is it right?
if i want use uart2(ttymxc1),is there a solution for it ?
looking forward your reply.
best regards
zhang
Hi zhang
uart wake up procedure is described in sect.21.1.5 Unit Test
attached Linux Manual. Example of dts uart settings:
linux/arch/arm/boot/dts/imx6sll.dtsi
imx6sll.dtsi\dts\boot\arm\arch - linux-imx - i.MX Linux kernel
Best regards
igor

i enabled the ttymxc0 and ttymxc1, both of them can wakeup the system.
if ttymxc0 disabled, ttymxc1 can not wake up the sys/
