Hi list
I dug out my XOs to check their condition and my XO-1.75 (SKU203) refuses to boot as if it was wiped out clean or has no microSD card at all.
The screen comes up and nothing further.
Firmware check just show a double zero [00] 
Trying to install a fresh OS from USB fails (with the same double zero)
A fast wiki search did not come up with anything relevant.
If someone can point me to the right direction I would appreciate it.
Thanks

ESC doesn't give the prompt of the Forth PROM?

Hardware diagnostics?  Rocker left cheat code.

Thank you Peter,
But there is no way to get to the Forth PROM or get hardware diagnostics or anything on the screen other that the 2 big zeros mentioned above.
Looks like there is no firmware in this machine! 
As if the eMMC is wiped clean or missing.

This XO has a serial port connection attached
Any diagnostics through this?

Thanks
