B4J Question Which minimal OS with JAVA for embedded application

[Alessandra Pellegri]

I am going to start an embedded project and I think to use Raspberry programmed with B4J.

I would need a minimal OS for quick booting when the device is powered on.
I don't need XServer or any GUI. I just need to use Ethernet,Uart,I2C and SPI interface.

Do you know if is there any distribuition working out of the box ?

Thank you

Just for knowledge Minibian distribution (2016-03-12-jessie-minibian.img) on Raspberry 1 with installed Oracle-Java 8 can start to blink a led in 24secs from the boot.

Not bad. But if someone knows some distribution more speedy please tell me.

Thank you

Java 7+ is required. Java 8 is recommended and required if you want to use jServer library.
