Today I downloaded version 5.1.0 of FreeRTOS, installed it on Fedora 8, and tried to compile one of the AVR32 demos (so far no joy but I did find some earlier versions that build OK). My main objective right now, though, is to get FreeRTOS working on the AVR32-AP7000, specifically on the Atmel NGW100 board. This is my first shot at working with FreeRTOS. I know that there is a FreeRTOS-AP7000 project here on sourceforge (https://sourceforge.net/projects/ap7x-freertos/), but it doesn’t appear that much activity has taken place there since mid-2006, and the forums don’t have any messages in them except for "welcome" messages dated in June of 2006. I tried searching this forum for things like "AP7000" and "NGW100" but didn’t get any hits, so I assume that it’s not that the AP7X effort was just consolidated into this one. I went to https://sourceforge.net/projects/ap7x-freertos and downloaded the latest available AP7000 port, version 0.2 (the project web page said version 0.3 was available but I couldn’t find it).  I unarchived that in ./avr32freertos-0.2 on fedora 8, then went to ./avr32freertos-0.2/Demo/AVR32_AP7000_GCC/Demo/WebServer and said "make". It didn’t get far. avr32-gcc -c -Wall -D RUN_FROM_RAM -D TASK_SWITCH_USE_INT0  -DGCC_AVR32_AP7000  -DEMAC_INT=EX_INT0   -I. -I../.. -I../../../../Demo/AVR32_AP7000_GCC/support

I patched up main.c to eliminate the compile errors (put in dummy values for the undefined values) and then tried to continue the build. During the compile of port.c, I got the following list of errors (trimmed a bit to remove things like "Each undeclared identifier is reported only once…" etc.): ../../../../Source/portable/GCC/AVR32_AP7000/port.c:248: error: ‘AVR32_TIMER0_IRQ0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:284: error: ‘avr32_intc_t’ has no member named ‘intpr’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:291: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token ../../../../Source/portable/GCC/AVR32_AP7000/port.c:291: error: ‘timer0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:291: error: ‘AVR32_TIMER0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:297: error: expected specifier-qualifier-list before ‘avr32_timer_cmr_t’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:302: error: expected specifier-qualifier-list before ‘avr32_timer_ccr_t’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:305: error: ‘union <anonymous>’ has no member named ‘CMR’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:306: error: ‘union <anonymous>’ has no member named ‘CMR’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:307: error: ‘union <anonymous>’ has no member named ‘CMR’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:318: error: expected specifier-qualifier-list before ‘avr32_timer_ier_t’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:322: error: ‘union <anonymous>’ has no member named ‘IER’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:326: error: ‘union <anonymous>’ has no member named ‘CCR’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:327: error: ‘union <anonymous>’ has no member named ‘CCR’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:337: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token ../../../../Source/portable/GCC/AVR32_AP7000/port.c:337: error: ‘timer0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:337: error: ‘AVR32_TIMER0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:345: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token ../../../../Source/portable/GCC/AVR32_AP7000/port.c:345: error: ‘timer0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:345: error: ‘AVR32_TIMER0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:349: error: expected specifier-qualifier-list before ‘avr32_timer_ier_t’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:353: error: ‘union <anonymous>’ has no member named ‘IER’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:358: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token ../../../../Source/portable/GCC/AVR32_AP7000/port.c:358: error: ‘timer0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:358: error: ‘AVR32_TIMER0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:361: error: expected specifier-qualifier-list before ‘avr32_timer_idr_t’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:365: error: ‘union <anonymous>’ has no member named ‘IDR’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:371: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token ../../../../Source/portable/GCC/AVR32_AP7000/port.c:371: error: ‘timer0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:371: error: ‘AVR32_TIMER0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:377: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token ../../../../Source/portable/GCC/AVR32_AP7000/port.c:377: error: ‘timer0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:377: error: ‘AVR32_TIMER0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:380: error: expected specifier-qualifier-list before ‘avr32_timer_ccr_t’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:384: error: ‘union <anonymous>’ has no member named ‘CCR’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:391: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token ../../../../Source/portable/GCC/AVR32_AP7000/port.c:391: error: ‘timer0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:391: error: ‘AVR32_TIMER0’ undeclared (first use in this function) ../../../../Source/portable/GCC/AVR32_AP7000/port.c:395: error: expected specifier-qualifier-list before ‘avr32_timer_ccr_t’ ../../../../Source/portable/GCC/AVR32_AP7000/port.c:399: error: ‘union <anonymous>’ has no member named ‘CCR’ I checked some of the undefined identifiers and didn’t find them anywhere. I’m beginning to think I’m missing some files. Has anyone successfully built version 0.2? Are there files where things like AVR32_HEBI_DATA_16_PIN and AVR32_TIMER0_IRQ0 and AVR32_TIMER0 are defined, that are missing from the archive I downloaded? If not I can probably research them and make up some header files over time, but if someone has already done that I’d rather concentrate on something else that needs doing…
