Richard Barry 101806906d Rework RISC-V portASM.S to make it easier to add in chip specific RISC-V extensions and accommodate chips that don't include the CLINT. 2018-12-16 23:59:49 +00:00
Richard Barry 7cc42b2ab6 Save changes to the RISC-V port layer before making changes necessary to support pulpino too:
+ Switch positions of the asm functions used to start the kernel and handle traps to enable one to reference to the other.
+ Handle external interrupts (working with Renode emulator).
+ The _sp linker variable is now called __freertos_irq_stack_top.

Richard Barry 8d041c8e21 Update version number in preparation for maintenance release. 2017-01-22 05:28:13 +00:00
Richard Barry 992a3c8c71 Update BSP source files for UltraScale Cortex-A53 and Cortex-R5 and Microblaze to the 2016.4 versions.
Correct alignment issue in GCC Cortex-R port that was preventing full floating point usage in interrupts (other ports will be updated likewise).

2017-01-19 04:11:21 +00:00
Richard Barry 6ffaa6f018 Correct alignment issue in GCC and RVDS Cortex-A9 port that was preventing full floating point usage in interrupts (other ports will be updated likewise).

2017-01-18 18:33:48 +00:00
Richard Barry 75ffac21d7 Changes to core code and port layer:
+ Add configASSERT() into ARM Cortex-M ports to check the number of priority
      bit settings.
    + Clear the 'control' register before starting ARM Cortex-M4F ports in case
      the FPU is used before the scheduler is started.  This just saves a few
      bytes on the main stack as it prevents space being left for a later save
      of FPU registers.
    + Added xSemaphoreGetMutexHolderFromISR().
    + Corrected use of portNVIC_PENDSVSET to portNVIC_PENDSVSET_BIT in MPU ports.

Richard Barry c296e2cff8 Improvements to the Cortex-M ports:
- Clear the SysTick current value register before starting the SysTick (only required if something uses SysTick before starting the scheduler).
- Ensure atomic operations are thread safe by executing clrex in the context switch.

2016-05-19 13:28:12 +00:00
Richard Barry ee9cd40b6d Add GCC ARM Cortex-M4F MPU port.
Add RVDS ARM Cortex-M4F MPU port.
Increase the size of each buffer allocated to pbufs in the Microblaze lwIP demo to prevent pbufs chaining.
Use _start as the top of the stack for each Microblaze task, rather than NULL, as NULL was causing the Xilinx SDK to try and unwind the stack too far.
2016-05-18 10:41:28 +00:00
Richard Barry fedb98c5f6 Recreated MicroBlaze example using Vivado 2016.1 - the Microblaze project is still a work in progress - not yet fully functional. 2016-05-10 14:05:22 +00:00

Add MikroC Cortex-M4F port.
2016-04-25 17:24:54 +00:00
Richard Barry 0b5906d404 Remove obsolete MPU demos.
Separate the MPU wrappers into their own file so they can be used from future MPU ports.
2016-04-25 12:03:47 +00:00
Richard Barry afd4b432f6 Improve coverage of the MPU API in the new MPU demo, fixing typos in the MPU port layer as they are found. 2016-04-24 18:33:16 +00:00

Richard Barry 255145bde1 xTaskGetTaskHandle() changed to xTaskGetHandle().
Tidy up CEC1302 demo.
Ensure bit 0 of the task address is clear when setting up stack of initial Cortex-M3/4/7 stacks (for strict compliance, although not practically necessary).
vTaskGetTaskInfo() changed to vTaskGetInfo() - with a macro added for backward compatibility.
2016-04-15 11:48:07 +00:00
Richard Barry f1725afbe5 Remove compiler warning by ensure prvInitialiseMutex() is not included if configUSE_MUTEXES is 0.
Reduce the number of xTaskCreateStatic() parameters by having the function return the task handle, rather than pass the task handle out using a parameter.  This is also consistent with other objectCreate() functions.
2016-03-31 15:22:10 +00:00
Richard Barry 07ac1399ee Update version number to 9.0.0rc2. 2016-03-30 12:20:36 +00:00
Richard Barry b9b64c0889 Make the pcObjectGetName() API function naming consistent - so rename pcTaskGetTaskName() to pcTaskGetName(), rename pcTimerGetTimerName() to pcTimerGetName() and add a #defines in FreeRTOS.h to make the changes backward compatible. 2016-03-29 17:16:34 +00:00
