Hi Simon,
Last weekend I tested a bit your lwip 1.3.1 port. Well, that was not any
stress test, just compile and run a few net tests out from the box and
pinging. Short summary the below
Synth ARM-7 (LE)
+ http_simple + http_simple
+ http_sequential + http_sequntial
+ tcpecho + tcpecho
External ping/arping worked for both targets. For the tests I used
configs with DHCP support.
For the followers I attach the ecos minimal configs which I used for
simple and sequential modes for synth and real hardware and a small
patch for simple.c, sequential.c. All build were started as
ecosconfig new <target> lwip_eth
I had got `stack overlow' in GDB with default stack's settings on real
target when I enabled a tracing and turned off optimization, I tried
multipy stack amounts (for interrupts, tcp_thread, eth_thread) x 2, x 4,
but error did not go away. Perhaps, I should investigate more time for
the issue, but may be in the next weekend.
Thanks for the port!
Regards
Sergei
