Hi all,
I'm testing suspend resume with latest TI SDK 02.00.02 on AM3354 but I'm
observing some strange behaviours.
1) GPIO banks
It looks that GPIOs from banks different from 0 are not able to resume
the neither in mem, nor in stanby mode: is the expected behaviour?
2) TSC
It looks that the first time you suspend the board is not able to cause
the wakeup, but if you wakeup in any other ways, the following times the
TSC correctly wakeup the board.
3) USB
According link
http://processors.wiki.ti.com/index.php/AM335x_Power_Management_Standby_User's_Guide#USB_wakeup
the USB should wakeup the board, but nothing happen.
4) UART
According link
http://processors.wiki.ti.com/index.php/AM335x_Power_Management_Standby_User's_Guide#Wakeup_Sources
the UARTs could be allowed to wakeup the boards, but the procedure does
not apply (invalid sys path)
Anyone tested wakeup sources with AM3354?
Any suggestion or workaround?
Thanks
Regards
Pierluigi
