FreeRTOS on HCS08

jeffw — Sat, 18 Mar 2006 05:17:06 GMT

I've ported FreeRTOS to HCS08, and the project targets the SARD and EVB boards. I'm working on making SMAC compatible with this project.

Steps

1. Download and install FreeRTOS 3.2.4: FreeRTOS
2. Download the attached zip file
3. Unpack it into a temporary directory.
4. Following the FreeRTOS directory structure, move the sub-folders into their correct places.
5. Open the RTOSDemo.mcp project in CW 3.1.
6. Deploy to a Freescale SARD or EVB.

Hi, Jeff:

Will this port run on the HC08 (non-S) as well?

I don't see why not, but I'm not aware of all of the differences. I haven't used an HCS08 part yet, outside of the ZigBee kit (which we dumped).

The project uses the Processor Expert, so it is pretty easy to port to any MCU supported by that tool. (Yes, PE is good and bad - I know.)

Wouldn't it be cool to have GCC for HCS08? (And Eclispe and an Eclipse BDM plugin.) Any takers?!

I'll take it in a snap... The hard part would be to provide it :smileywink:

I have a version of FreeRTOS for both the HC08 and S08. For the HC08 you just have to be careful on the ASM code that makes the context switch since that can be optimized using S08 instructions. Other than that, the code is very similar. Let me know if you are interested I can post it here.

Dear RT:

I'm interested in your FreeRTOS for HC08. I'm currently working on a project with the MC68HC908GP32 and would like to review your FreeRTOS for HC08 in order to consider using it on this chip. Could you please post your FreeRTOS for HC08? Thank you very much.

Best regards,

Miguel

I just sent you a copy of the RTOS to your personal email.

Please let me know if you have any questions or comments.

Regards

RT,

You could also submit a version of the RTOS to the "8-Bit Microcontroller Community".

Thanks

I was wondering if you had ever posted the HC08 version of this RTOS on the forum? The link states it is for the HCS08. Are they the same?

Thanks!

Brian

Hi Jeffw.
Could you send me the RTOS for HC08 or give me a link to download this file, I'm working in this kind of microcontrollers in CW5 and I'm very interesting in this topic, but I don't have information about it,
Thanks a lot.

Dear everybody

Could anybody tell me how to port the FreeRTOS on HCS08 to HC08 (GZ60)?

Thanks,

Khoa

I have problems compiling FreeRTOS. I followed the instructions, but when I try to compile, I get this error 10 times:

"Error : C2450: Expected: ; "

for this line in portable.h:

"portSTACK_TYPE *pxPortInitialiseStack( portSTACK_TYPE *pxTopOfStack, pdTASK_CODE pxCode, void *pvParameters ); "

My CodeWarrior version is 5.7.0 and it converts automatically CW 3.1 projects to newer version. Maybe this is the reason for the problem??

Re: FreeRTOS on HCS08

tranvkhoa — Mon, 14 Aug 2006 16:52:56 GMT

Maybe it's because your CW is special edition. If so, you should buy the pro edition. Do you have FreeRTOS for HCS08 or HC08? If you have the one for HC08, please send to me at tranvankhoa@gmail.com. Thanks.

Re: FreeRTOS on HCS08

arskii — Mon, 14 Aug 2006 17:03:08 GMT

I have CW Standard Edition and FreeRTOS for HCS08.

Is there any message related to license limitation error?

Re: FreeRTOS on HCS08

arskii — Mon, 14 Aug 2006 17:27:55 GMT

No licence errors. Only that one error 11 times, not 10 as I told before..

I am just curious if anyone has gotten the Free RTOS for the HC08 yet? I have seen several posts asking about it but have not seen any posts telling where it is. Anyone Know????

Dear bespenschied:

Back in april of this year I got a response from Rene Trenado regarding FreeRTOS. He kindly offered me a ZIP file containing FreeRTOS for the HCS08 together with a set of instructions regarding its use. The following message contains these instructions. The ZIP file has been attached to this e-mail. If you have any questions regarding FreeRTOS please refer them to Rene Trenado at rene.trenado@embeddia.com as I am not well versed in FreeRTOS.

Best regards,

Miguel

Asunto: Re: FreeRTOS on HC(S)08

Hi,

Sorry for the late response. Here is the CW project that implements FreeRTOS to the HC08 / S08. The project was meant to be used for a S08 GB60/GT60 board with an 32kHz xtal. Please disregard the initialization of PORTF and the ICG on main.c

The sample application just creates two tasks (plus the IDLE task used by the RTOS). Each of them go to "sleep" at a different frequency. This is the simplest example I could think of (I have others of course).

To use the code I am sending to you just cut and past the FreeRTOS folder and GT60 HAL under sources of your project root folder. Rename the GT60 HAL folder to GP32 or whatever and provide your own TickTimer.h and TickTimer.c files (the Timer used by the RTOS to generate the tick interrupts). You just have to provide the following timer functions:

TickTimer_SetFreqHz( configTICK_RATE_HZ );

TickTimer_Enable();

which are called by port.c by the way...

If you have any questions or comments please let me know.

Saludos y que estes bien

Miguel,

Thanks for the reply and the files. I used to use an RTOS on the 6811 and it was a good way to handle several programs I needed.
