I found a small mistake in the source file(2.7),when i transplantsed the contiki to the STM32F10x platform.It take me a whole noon to find it out.(IAR5.3 for arm +stm32f10x firmware) NOTE: make sure that 'SysTick_Handler' in startup_stm32f10x_md.s of STM32 official firmware conform to the 'SysTick_handler' function of clock.c which directory is /cpu/arm/stm32f103.Obviously h do not comform to 'H'. forgive me poor english :)
