I just downloaded FreeRTOS 5.0.0 and tried to build with the latest avr32-* GNU toolchain from Atmel & got several compile errors.  It looks like the Atmel header files possibly changed. First try: $ make clean $ make Compiling `../../BOARDS/EVK1100/led.c’ to `../../BOARDS/EVK1100/led.o’. ../../BOARDS/EVK1100/led.c:77: error: ‘AVR32_PWM_PWM_0_FUNCTION’ undeclared here (not in a function) ../../BOARDS/EVK1100/led.c:77: error: ‘AVR32_PWM_PWM_1_FUNCTION’ undeclared here (not in a function) ../../BOARDS/EVK1100/led.c:77: error: ‘AVR32_PWM_PWM_2_FUNCTION’ undeclared here (not in a function) ../../BOARDS/EVK1100/led.c:77: error: ‘AVR32_PWM_PWM_3_FUNCTION’ undeclared here (not in a function) make: *** [../../BOARDS/EVK1100/led.o] Error 1 So in evk1100.h I changed AVR32_PWM_PWM_x_FUNCTION to AVR32_PWM_x_FUNCTION – problem solved. Second try: $ make clean $ make Compiling `../../BOARDS/EVK1100/led.c’ to `../../BOARDS/EVK1100/led.o’. Compiling `../../DRIVERS/INTC/intc.c’ to `../../DRIVERS/INTC/intc.o’. ../../DRIVERS/INTC/intc.c:52: error: ‘AVR32_INTC_IPR0_INTLEV_SIZE’ undeclared here (not in a function) ../../DRIVERS/INTC/intc.c: In function ‘_get_interrupt_handler’: ../../DRIVERS/INTC/intc.c:111: error: ‘avr32_intc_t’ has no member named ‘icr3’ ../../DRIVERS/INTC/intc.c: In function ‘INTC_register_interrupt’: ../../DRIVERS/INTC/intc.c:199: error: ‘AVR32_INTC_IPR0_INTLEV_MASK’ undeclared (first use in this function) ../../DRIVERS/INTC/intc.c:199: error: (Each undeclared identifier is reported only once ../../DRIVERS/INTC/intc.c:199: error: for each function it appears in.) ../../DRIVERS/INTC/intc.c:199: error: ‘AVR32_INTC_IPR0_INTLEV_OFFSET’ undeclared (first use in this function) make: *** [../../DRIVERS/INTC/intc.o] Error 1 This time I’m not sure what AVR32_INTC_IPR0_INTLEV_SIZE should be mapped to. Any ideas? Here are the avr32 versions I’m using: -————————————– avr32parts-1.9.9-1.fc8 avr32-gdb-6.7.1.atmel.1.0.3-1.fc8 avr32headers-1.9.11-1.fc8 avr32program-3.0.4-1.fc8 avr32-binutils-2.17.atmel.1.2.6-1.fc8 libavr32ocd-3.0.8-1.fc8 avr32trace-2.0.3-1.fc8 libavr32sim-0.2.1-1.fc8 avr32-gcc-newlib-4.2.2-atmel.1.0.8_1.fc8 avr32gdbproxy-3.0.11-1.fc8 Thanks, Wes

Thanks for pointing this out.  I have searched through the header files and come up with this: #define AVR32_INTC_IPR0_INTLEV_SIZE  2 This was in intc.h, which was marked as revision 36724, Fri 16th March 2007. There has been some confusion over the AVR32 headers for a while, but this was historically more to do with the IAR builds than the GCC builds. Atmel provide their own FreeRTOS.org projects that can be downloaded from the Atmel WEB site.  It might be worth looking at these to see what they have changed these constants to.  I will have to download the latest tools to make updated. Regards.
