If you download the FreeRTOS.org code, then compile the lwIP demo (for the SAM7X) you will be able to see how much ROM each component takes using various different optimisation options. If you compile using CrossWorks then the sizes are displayed in the project explorer, which will be a bit easier than going through the map file. The RAM usage is very dependent on the requirements of your chosen MAC and the throughput you require. These are very configuration in lwIP. You might want to also look at uIP if memory is a problem.

Thanks.But What is SAM7X? I got the code from http://savannah.nongnu.org/projects/lwip/.

USB driver problem LPC-2148
2006-06-01 by pratik pujar
Hi everybody,
I am using LPC 214x USB stack (open source can be downloaded from https://sourceforge.net/cvs/?group_id=160384 ) on my proprietary ARM board with LPC 2148 microcontroller chip.
But I am facing problems.
When i run it , and plug in then USB LINK led lights up and when unplugged goes off.
But my linux machine is not able to detect any USB device when plugged in and on windows machine it shows "Unknown USB device attached."
When i enable debug prints then results what i found is that the device is not getting end point (EP SLOW) interrupts.
Where as at the end of main function there is continuous while loop polling for interrupt. In which it checks value of USB device Interrupt status register(0xE0090000) and accordingly call handler routines.
Am i missing with anything ? is there anything i need to do?
Please help me.
Thanks & regards,
Pratik.

Hi ,
Sorry that link for open source was wrong so making a correction
It is (LPC -214x USB Stack)
https://sourceforge.net/projects/lpcusb
Thanks & regards,
Pratik.
