eZ80F91 ZDSII port

Posted by Nobody/Anonymous on May 3, 2005
I developed a new port to the eZ80F91 development kit using ZDS II 4.9.1 and need to know how to send the files to add to the sources tree.

Excellent!

You can send the source to me at the email address listed on the ‘contacts’ page of the FreeRTOS.org WEB site. I can then make it available for download.

There are a couple of optional things you can do to make the port as useful as possible to others -

The first is to provide a simple demo application. This can use the existing demo application files or some of your own. A demo to get a few LED’s flashing is a good minimum.

The second is to include some notes along the following lines:

+ Your name – so I can credit you with the port
+ A link to the compiler/tools you used
+ A link to the development board you used
+ Instruction on how to build the code
+ What the demo does (if there is one).

You can take a look at the other port html files (eg http://www.freertos.org/portlpckeil.html) to see the kind of information.

Is your code based on FreeRTOS V3.0.0? This would be ideal. I can help you change to V3.0.0 if not.

Thanks – Richard Barry.

I am testing your port. I would like to tell you that the port fails if last RAM address (in the linker settings) is 0xFFFFFF because of a Zilog's BUG in sbrk.asm used by malloc (in fact the load this address in bc register and then add '1' so bc goes to '0x000000' and the whole thing fails).
I will fix sbrk.asm by myself and try it.

Hi,

I have just started the process of generating an official port from the current unsupported port. So far I just have the hardware and a hello world type program running - I have not even yet run the existing port - so it will be a while until this is ready.

Anyway - any information you can give like this will be very helpfull. I can encorporate any bugs you find into the official eZ80 FreeRTOS release.

Regards.

I know this is an old posting of yours.

I found this link regarding an eZ80 port http://www.freertos.org/portez80.html and I was wondering if this ever made it to your roadmap. I have a port running with 7.4.2 and just the 2 UARTS supported so far. If you're interested I would enjoy helping move this into the support realm.

Gosh you did well finding that, I didn't even know it was there ;o) It seems to date back to 2005! Where did you find the link to it?

I'm afraid it is not something that is going to become an official port, but I would be very pleased if you were to upload your code to the FreeRTOS Interactive site.

Regards.

It is the 11th item if you google 'eZ80'
