RE: [ECOS] Re: AT91SAM7SE - multiple defintion of CYGNUM_HAL_RTC_PERIOD

Hi John,

Thanks for the response. That caused me to have another look at my board
package. Comparing it to the at91sam7sek I see that I was not properly
including hal_arm_at91sam7.h in the package CDL's define_proc..

The build is completely clean now. 

Cheers,

Brian
