lwip 1.3.1 testing
Hi
I have done a new lwip test release with the following changes:
* incorporated Sergei's patch (ctrl-c support)
* added an lwip_eth_simple and lwip_eth_sequential template
The new test release can be downloaded from
http://download.westlicht.ch/lwip-20090825.tar.gz
To do synth tests do the following:
create a new configuration:
> ecosconfig new linux lwip_eth_simple
or:
> ecosconfig new linux lwip_eth_sequential
enable eth0 synth device (file is attached):
> ecosconfig import eth_synth.ecm
build:
> make
> make -C build/net/lwip_tcpip/current tests
run tests (a sample target.tdf is attached):
./build/install/tests/net/lwip_tcpip/current/tests/httpd_simple -t
target.tdf -io -nw
The current templates use DHCP to get an IP address. Just reconfigure
for static IPs.
To do some stress testing you can run the nc_test_slave testcase (only
available in sequential mode). You will need the corresponding master
test, which can be found in the ecos repository under
packages/net/common/current/tests
To build the nc_test_master go to the upper directory and type:
> make -f make.host
Also you should loosen up the very conservative default configuration of
lwip pbufs to avoid dropped packets:
> ecosconfig import pbufs.ecm
> make && make -C build/net/lwip_tcpip/current tests
Testing on real hardware would be especially useful. Also testing on
big-endian targets might reveal some issues, as I've only been testing
on little-endian platforms.
Thanks a lot for testing!
