[snip] > I will test your newest patch on synthetic target for 2.6.32 kernel Ilija, I have tested nc_test_{master,slave} for synthetic target and NET template (all NC tests passed as I could expect). The eCos settings were cdl_configuration eCos { template net ; }; cdl_option CYGPKG_NET_BUILD_HW_TESTS { user_value 1 }; Hm, not patched lwip' NC test (slave) on synthetic target stalled when background load is 30% (for BSD stack all loads passed on eCos synthetic target) Set background load = 30% Request 18 from 192.168.1.1:7776 UDP echo - 2048 buffers, 1024 bytes Packets out of sequence - recvd: 1, expected: 0 And patched one for 20% load (no 'Segmentation fault' anymore) Set background load = 20% Request 18 from 192.168.1.1:7776 UDP echo - 2048 buffers, 1024 bytes Packets out of sequence - recvd: 1, expected: 0 So, it seems to me it is another issue with test itself. It would be good to know, All the lwIP NC tests/loads passed on your real hardware? For reference, I used the next eCos configs to build both lwIP' tests cdl_configuration eCos { template lwip_eth ; }; cdl_option CYGVAR_DEVS_ETH_ECOSYNTH_ETH0 { user_value 1 }; cdl_option CYGFUN_LWIP_MODE_SIMPLE { user_value 0 }; cdl_option CYGFUN_LWIP_MODE_SEQUENTIAL { user_value 1 }; -- Configure bugmail: http://bugs.ecos.sourceware.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
