Dear Friends,
I am having AM335x EVM, and currently using TI's latest SDK 05.06.00.00 for development. While testing the Suspend/Resume functionality using the 05.06.00.00 kernel source, found that the device gets in to SUSPEND state but couldn't able to RESUME it even by touching the Touchscreen or UART input.
With the Previous SDK version 05.04.01.00 , the Suspend/Resume works fine.
Can anyone confirm that if the Suspend/Resume functionality works with 05.06.00.00 SDK or not? or share suggestions.
Command Used to put system into Suspend: "sync; echo mem > /sys/power/state"
Thank you,
Ankur
Please find the nonworking Suspend/Resume kernel log below from default 05.06.00.00 SDK:
