Memory footprint of MQX+MSF+RTCS on MCF51CN ?

cocheca — Fri, 22 Oct 2010 08:35:05 GMT

Hi,

I want design an application with MCF51CN. And I need use MQX-OS with MSF and RTCS. But, the built of the basic project became in more than 100KB of flash memory.

- That is correct ?

- Is possible to reduce the memory footprint ? (MCF51CN has only 128KB)

- Any recommendations for me ?

I saw that other OS, like FreeRTOS plus LwIP have lower memory footprint. But, I would like to use the MQX.

Thanks for your help

Regards, Jose.-

Hi, MQX has lot of conditionally compilable parts which can save your Flash space.

I would suggest to disable off all:

kernel features you do not use

drivers you will not use in your application ( GPIO and ADC are quite big, better to write your custom implementation if you need small footprint BSPCFG_ENABLE_GPIODEV, BSPCFG_ENABLE_ADC

set to 0)

RTCS services you don't need in your application. (RTCSCFG_ENABLE_ICMP, RTCSCFG_ENABLE_UDP)

Also you can see MQX kernel components and diver sizes in the :

"c:\Program Files\Freescale\Freescale MQX 3.6\mqx\examples\benchmrk\codesize\results\twrmcf51cn_cwmcu63_regabi.html"
