FreeRTOS compile issue

[Erdyke]

Running FreeRTOS bean on Codewarrior (MCU) for DEMO09S08DZ60 board. Bean settings are default.

1) Looks like function "UBaseType_t FRTOS_AppGetRuntimeCounterValueFromISR(void)" is being re-declared because of a different return value type.

2) Also enabling Custom portBASE_TYPE seems to totally mess up the compiler in that I get error "C1067 missing decl specifiers" and error "C2450 Expected ;" at Line 181: "BaseType_t xPortStartScheduler( void ) PRIVILEGED_FUNCTION;" in "portable.h"

I have not used it for S08 for a while. So it could be that something is broken. I'll have a look and report back.

[ErichStyger]

Hi Erdyke, Indeed, things are broken for S08 if using a dedicated timer :-(. I have commited a fix here: https://github.com/ErichStyger/McuOnEclipse_PEx/commit/b55ffa579e596494b1dd2396cb4e9f532e6618b1 Can you check if this solves the problem on your side as well?

I appologize for the issue, Erich

[Erdyke]

Will do,

Regards, Eric Dyke

Hi Eric, I have fixed as well the secone issue with custom base types: https://github.com/ErichStyger/McuOnEclipse_PEx/commit/7362338383bf2912081df7fdfa026b12c48b8a7c

Sorry as well for this issue, I have never used custom base types :-(.

Let me know if this is fixed on your side too so I can close this issue.

Thanks, Erich

[Erdyke]

Thanks. I will need to get to it tonight.

[Erdyke]

The first fix allows things to compile fine. I have not tested the other fix. I'm pretty new to FreeRTOS so I will need to play around with it on my demo board to see how it runs with the default settings. Thanks for all the work you do!

[ErichStyger]

Thanks, and you are welcome. I'm closing the issue now. Be free to report if there are any problems or if there is anything to reopen the issue.

Perhaps I'm missing something, but I cannot get a regular LED demo to run using default settings with a task delay of 500 ms. Do I need to do anything with the events created from the bean?

[ErichStyger]

No, nothing special to set up, and no special event handling needed. Below some code:

static void AppTask(void* param) { for(;;) { LED1_Neg(); vTaskDelay(pdMS_TO_TICKS(500)); } }

if (xTaskCreate(AppTask, "App1", configMINIMAL_STACK_SIZE, NULL, tskIDLEPRIORITY, NULL) != pdPASS) { for(;;){} /* error case only, stay here! / } vTaskStartScheduler(); /_ start the RTOS, create the IDLE task and run my tasks (if any) */

[Erdyke]

As before, it looks like the tasks are getting created okay and are executed. I can set a breakpoint at the LED1_NegVal(); and see we get there each time. But there doesn't seem to be any real delay. I'm instantly returned to the BP after continuing.

In case it's useful, I uploaded my project: https://github.com/Erdyke/FreeRTOS-DEMO

[ErichStyger]

Yes, that's useful. I don't have that S08 device, but I think I have found your issue: you have the Software Interrupt not properly configured. It is an older article, but the settings for FreeRTOS still apply, have a look at https://mcuoneclipse.com/2012/06/28/tutorial-freertos-on-demojm/. The swi needs to be configured properly (https://mcuoneclipse.files.wordpress.com/2012/06/assigning-software-interrupt-vector.png?w=584). The other thing is: your heap is set to 2KByte. That's fine for a few tasks. You might increase that one later. I hope this helps, Erich

[Erdyke]

That's the fix. Thanks for the help. Much Appreciated!
