2011

2011-01-01

• update code to refer to avr8 instead of avr
  • update references to folder name avr8
  • update macro definitions to use *_AVR8 instead of *_AVR
• wiki Prerequisites page split into How to install/How to use/How to port

2011-01-02 - 2011-01-15

• TBD

2011-01-16

• team project set WorkspaceTeamProjectSystemAndSampleSets.psf updated

2011-01-18

• TEMPLATE code added; purpose is to have a code that compiles, as basis for future ports
  • ../arch/TEMPLATE_ARCH/
  • ../arch/TEMPLATE_ARCH/TEMPLATE_FAMILY/
  • ../boards/TEMPLATE_MANUFACTURER/
• AVR32 code added, based on TEMPLATE
  • ../arch/avr32/
  • ../arch/avr32/uc3/
  • ../boards/Atmel/evk1104/

2011-01-19

• os_processor_init() with data & bss init ok
• constructors run for avr32

2011-01-24

• com.atmel.avr32.core.nature added to make it build for avr32
• OS_GPIO_PORT_CONFIG_OUTPUT/INPUT added
• putString_P(PSTR(…)) fixed as alias to putString(), based on OS_INCLUDE_SEPARATE_PROGMEM
• yield() always added to idle task, this makes cooperative mode automatic
• critical sections shortened in OSDeviceDebug.cpp
• program starts at os_reset_handler
• avr32 contextSave/Restore code included (based on FreeRTOS port)
• project Eclipse/samples/blinkX3Coop added
• APP_CONFIG_LED_ISACTIVE_LOW added

2011-01-25

• OS_GPIO_PORT renamed as OS_GPIO_PIN

2011-01-26

• in naming conventions, OS_CFGVAR_xxx nad OS_CFGPTR_xxx added
• avr32 functional system timer, mark second on debugger output
• project Eclipse/samples/blinkX3BusyWait added
• avr32 criticalEnter/Exit implemented with SR mask and stack

2011-01-27

• SysTick_contextHandler distinct from ISR, due to naked nature we cannot have local variables
• project Eclipse/samples/blinkX3Preemptive added
• build changed from CDT Internal to GNU Mak
• scheduler implementation code moved to OSSchedulerImpl

2011-01-28

• initialisation code moved from avr32 to portable folders
• CPUstackInit added, to make initialisation possible in C
• OS_INCLUDE_OSSCHEDULER_TIMER_MARK_SECONDS added
• project Eclipse/samples/compileAllSources added; the purpose is to test compile as many sources as possible

2011-01-30

• reset bits as OSResetBits_t
• conditional OSTimer, conditional preemption
• all ticks interrupt code collected in OSTimerTicks.cpp
• implInit() and implAcknowledgeInterrupt() added as private in OSTimerTicks.h
• common bitbanging code moved to portable/devices/debug/include/DeviceDebugI2C_Inlines.h
• ledActive code moved to portable folders
• OSImpl::CPUfetchResetBits() added

2011-02-01

• project Eclipse/samples/nestedInterrupts added
• OSScheduler:: schedulerTicks() renamed as *OSScheduler:: schedulerTick()

2011-02-02

• OS::busyWaitMicros() added
• OSScheduler::applicationInterruptTick() added
• in OSTimerTicks::interruptServiceRoutine(), critical section reduced only to interruptTick() and incrementTicks(); OSScheduler::interruptTick() moved outside
• OS_INCLUDE_OSTIMER_TICKS_ISR_TEST_LED added
• OS::busyWaitMillis(unsigned int) prototype changed
• OSTask::schedulerTick() no longer executed in critical section

2011-02-05

• be sure interrupts remain disabled before restoring first context
• isContextSwitchAllowed() written in C; the assembly code uses generic registers
• os_exception_handler() does soft reset on release
• OSApplicationImpl added
• applicationInterruptTick() moved to OSApplicationImpl::interruptTick()
• requireContextSwitch() renamed isContextSwitchRequired()
• contextSwitch() renamed performContextSwitch()
• ISR_ledActiveOn() moved earier in interruptEnter()

2011-02-07

• buildDateTime[] added to debug greeting
• avr32 os_exception_handler() extended with description string
• OS_EXCLUDE_OSTIMERTICKS_PREEMPTION added
• implAcknowledgeInterrupt() added to the end of the timer ISR

2011-02-08

• inclusion order changed for OS_Defines.h: first family and then architecture
• test with critical section in eventWait()
• implAcknowledgeInterrupt() called at the beginning of the ISR, to give a chance to next interrupt
• interruptEnter/Exit always save/restore registers, even when preemption is disabled
• SCALL critical section no longer implemented with stack

2011-02-10

• typedef OSProgramPtr_t added in arch/avr32/kernel/include/OS_Arch_Defines.h
• __dso_handle() added for avr32 when the first tests with streams were performed
• pointers as unsigned int instead of unsigned short in ostream_OSTask.cpp
• nested interrupt work on Avr32
• idle task stack size increased for Avr32 tests

2011-02-18

• OSEventFlags::wait() return type changed to OSReturn_t
