almost every brand new CC2 owner falls into this trap I think.
Unlike the Hostmode, where you can see it on the LCD display,
you get absolutely NO indication when the unit is in boot mode !
Just send the new OS.HEX file over the serial interface, after pressing
Reset and Boot keys exactly how you described it before. It should work.
The voltage level of the boot line seems to be OK for me.
TTL-low level is below 0,8 Volt. And 2,5 Volt is definitely more than this.
