M52235EVB Porting...

Posted by Karion Guerra on June 9, 2009
Hi to All,
I have this board with Coldfire MCF52235.
I just saw the porting for the M52221DEMO evaluation board wich uses the Coldfire MCF52221.

Is it possible to port the same project to M52235EVB? There are diferences to pre configure?

Yes it is definitely possible. The main thing to watch out for are the interrupt vector numbers used by the port layer. These may need to change, but I think this is described on the FreeRTOS WEB site.

There is also an MCF52259 demo in the FreeRTOS download.

Write to me directly at (r dot barry at freertos dot org) if you would like a quote for us to perform the port for you.

Thx for your advice, I'll try to port it myself, but if I canĀ“t do that i contact you.

Looking inside the Coldfire_MCF52233_Eclipse Demo, all files has the name for MCF52235. I would like to know if i can use this demo project to run in my M52235EVB without changes.
I have already dowloaded it to the board and leds are blinking like the example.

Sounds like you have your answer already. Did you see this page

I had start the porting process for this Demo. But Its already done, Looking the MCF52235_GPIO.h I saw that this Demo fits exactly to the MCF52235 microcontroller, but the Demo title says it is for M52233Demo board.
But if you see the porting files, they has the definition of all resources of M52235EVB. including the UART2 that MCF52233 dont hah.

I Put this Demo to run in my M52235EVB board and all is doing fine. The ethernet leds are ok, the IO leds are ok too. I can ping it.

So maybe this demo is for the M52235EVB and it can runs on the M52233DEMO becouse the second one dont use all resources the first one has.
MCF52233 has only 4 IRQs and MCF52235 has 15 and all of them are in the source code.

So im using it directly on the board and all is going fine for me.
