Hi Chris, I have enough RAM, I am using external SDRAM, so I have about 2MEG SRAM. And all lwip buffers mem and memp is taken from here through heap.

 

 

Kind Regards,

If you're not too far into your project, I would suggest taking a look at an NXP LPC23xx/24xx MCU.  If you are interested in Enet performance, those ARM7 parts have more speed and RAM than what you are using, and RAM for buffer space for Enet is very important.  The UC3A0512 only has 64k RAM.  You can easily burn up half that RAM just on buffers and such for Enet.  I wouldn't do any serious Enet work without at least 96K for RAM, and having more is certainly a help.

 

FreeRTOS is fine, and I would also suggest you use lwIP in RAW mode.

 

Chris.
