Hi, I just made the port of TinyOS-2.1.2-rc1 for the Zigduino platform, an arduino clone with atmega128rfa1 chip. The porting was pretty simple since the atm128rfa1 is already supported. The only issue I had was related to the missing RTC on the zigduino which is used by TimerMilli and Alarm62khz components. I made everything work by applying the following changes: - I re-wired AlarmMilli32C and CounterMilli32C to AlarmMicro32C and CounterMicro32C respectively - I used AlarmMicro32C and LocalTimerMicroC in the RFA1DriverLayerC - I redefined TRadio as TMicro and set RADIO_ALARM_MICROSEC to 1 and RADIO_ALARM_MILLI_EXP to 0 in RadioConfig.h
With these changes I've been able to successfully run Blink, RadioCountToLeds,tests/TestNetworkLPL and tutorial/Printf . However I think there is a cleaner way to get the millitimer and 62khz timer to properly work on zigduino. In particular I think there is a way to tell tinyos to use the XTAL1 instead of OSC1 at least for Alarm62khz. I tried to set SYM_TIMER_MODE to ATMRFA1_CLKSC_XTAL in TimerConfig.h but it has not worked. Probably I missed some steps but I get lost with all those timers :S Does somebody have any suggestion?
