ARM Development Studio missing pack ...

Hi Stephen,

I need to reuse code written for FreeRTOs, so I should use this.

I tried what you told me "[SAMA5D2] Blinky_RTX5_AC6" but I get errors in compilation:

The compilation of "CMSIS-RTOS2 FreeRTOS Blinky CA9 AC6" happens successfully.

I look forward to some solution.

Thanks very much.

Hi again debugasm

I'm really rorry that the "[SAMA5D2] Blinky_RTX5_AC6" example also fails to build.  Again, I can reproduce this and am checking with our Development Team on a workaround.

I am pleased to hear you now have the CMSIS-RTOS2 FreeRTOS Blinky CA9 AC6 (Fixed Virtual Platform)" example built.  Have you tried running it on the Cortex-A9 model, using the supplied "Blinky_CA9_AC6.launch" debug launcher?

To see the threads in the OS Data view, ensure you enable FreeRTOS support in the OS Awareness tab, and compile with the following compiler flags:
    -DportREMOVE_STATIC_QUALIFIER
    -DINCLUDE_xTaskGetIdleTaskHandle
    -DconfigQUEUE_REGISTRY_SIZE=n (where n >= 1)

You can then try porting this to your SAMA5D27 board (that has Cortex-A5 rather than Cortex-A9).

Hi Stephen,

sorry I'm late but in Italy last Friday was a party "November 1st all the saints".

The Cortex-A9 virtual platform works perfectly as you indicated.

I hope I can do something before my evaluation license expires.

I'm waiting for good news.

Thanks very much.

Are there any news about it ?

Hi debugasm

Our development team are working on fixes for the two failing examples.
I can send you the necessary changes for the "[SAMA5D2] Blinky_RTX5_AC6" example already if you need them.

However, the error messages you saw with your FreeRTOS project, e.g.:
ARM.FreeRTOS::RTOS.Config.FreeRTOS - Additional software components required
are because there is no FreeRTOS pack support available yet for Cortex-A5.

FreeRTOS pack support is available out-of-the-box for Cortex-A9, but not yet for Cortex-A5 or -A7.
Software for Cortex-A5 is similar to Cortex-A9 (some changes will be needed in the startup code), so you could try porting the working "CMSIS-RTOS2 FreeRTOS Blinky CA9 AC6 (Fixed Virtual Platform)" example to your SAMA5D27 board.

Do you need to use FreeRTOS?  As an alternative, the Keil RTX5 RTOS is fully supported in the Packs for A5/A7/A9.

Hope this helps

Perfect is a great thing, if you can send it to me somehow, I can try to make it work on the card.

I understand, I didn't check if FreeRTOS has already ported to A5, maybe there isn't much work to do.

I need an operating system, I would have used FreeRTOs because I know it, I can still try RTX5.

Since the experts are fixing the errors, could they also create examples dedicated to the SAMA5D27-SOM1-EK1 board ?

Thanks very much.

Hi again debugasm

Here are the changes to the "[SAMA5D2] Blinky_RTX5_AC6" example.

In os_tick_pit.c, change
__WEAK int32_t  OS_Tick_Enable (void) {
to
__WEAK void OS_Tick_Enable (void) {
and remove its
  return (0);

Similarly, change int32_t to void for OS_Tick_Disable() and OS_Tick_AcknowledgeIRQ()

Sorry, I don't think we could take that on.  Best that you try this yourself.
