Hi folks
We built a custom board based on am3354 .
We are trying to put the board on RTC only mode using MAIN_ON_OFF_SW (GPIO) (see the attached photo).
* For clarification
- wakeup is connected to am3354 "EXT_WAKEUP" pin
- MAIN_ON_OFF_SW is connected to am3354 "GPIO2_21" pin
When the switch is not installed and by shorting pin 1 with VRTC 1v8 (using tweezers) The boards enters the mode fine.
But if we installed the switch back, and by pressing it (which is equal to connecting pin 1 with VRTC 1v8) the board start the RTC only mode and hangs at very high current giving the following message on the debug terminal “sched: RT throttling activated”
Any idea is appreciated
Regards
