Hello,
problem solved.
The TI TCP Stack now works very well also under stressful network.
I had only to resize the memory and the most critical was parameter was:
Global.memRawPageSize = 2100;
I increased the page size to 3072.
Here my full critical changes:
Number of frames: from 16 to 8
Frame buffer size: from 1024 to 256
Page size: from 2100 to 3072
All these info are well discussed on TI Wiki page "NDK Static Network Biffers" suggested from Steve.
Thanks
