Hi Navin,

Freescale MQX Real-Time TCP/IP Communication Suite (RTCS) can be configured to a memory footprint of 12 KB ROM and 2.5K RAM on CFV2, including kernel,task applications, LW Semaphore, interrupt stack, queues and memory manager.

Freescale MQX RTOS includes a project that helps to determinate the timing and code sizing of any project. You can find this in the path \mqx\examples\benchmrk\codesize\results
The code sizing depends on the kind of functions used in the final application. The benchmark project includes almost all the main components in MQX. This will provide the code size of these components.

Unfortunately we don't have the footprint numbers for USB stack.

We have footprint numbers for kernel

(see codesize benchmark results:

c:\Freescale\Freescale_MQX_4_0\mqx\examples\benchmrk\codesize\reports\report_compare_arm_tools.html)

USB footprint would depend very much from the usb class and user application.

I hope this helps :smileywink:

Regards

Sol
