Part Number: AM2732
Other Parts Discussed in Thread: AWR2243,

我在官方AM2732+2*AWR2243两片级联的Demo中导入了以太网模块，使能了CPSW，添加了PHY驱动以及LWIP协议栈。目前通过.map文件看下来，添加以太网模块前后MSS_L2空间占用情况如下：

添加以太网模块前：

添加以太网模块之后：

总共占用了MSS_L2内存360KB左右，这太夸张了，请问有什么好的办法来对以太网协议栈或其他占用内存比较大的部分进行裁剪吗？

Thanks！

Hi Nilabh Anand,

I imported the Ethernet module on the AM2732+2*AWR2243 cascade demo. After compiling, I found that this operation took up 360KB of memory in the MSS_L2. How can I do to reduce the ethernet usage of memory?

Hi currinwang

Could you please tell me what ethernet requirement do you have- Is it TCP CLIENT/SERVER or something else?
