Dear @Florian_K, thank you very much for the interest in our products and for using the Toradex Developer Community.
You have two options to implement a behavior similar to what you describe:
- Always ON Jumper (JP1): if you insert a shunt humper on the connector JP1, the Ixora carrier board will turn on automatically as soon as you provide the required power at the connectors X2 or X3.
You can find this information in section 126.96.36.199 on page 13 of the Ixora carrier board datasheet:
This jumper basically bypasses the push button controller circuit.
- Power Control Header (X5): this connector can be used to control the Ixora carrier board behavior. In particular, the pin 3 of the Power Control Header X5 can be used to override the Pushbutton controller.
If you provide 3.3V on this pin, the Ixora carrier board is Always On when power is applied to the connectors X2 or X3.
This information can be found in section 188.8.131.52 on page 13 of the Ixora carrier board datasheet.
I really hope this helps, please don’t hesitate to use again the Toradex Developer Community if required.
