Use the web interface provided at: http://bugs.ecos.sourceware.org/show_bug.cgi?id=1001696 Summary: cyg_ppp_up and cyg_wait_up sometimes never return Product: eCos Version: 3.0 Platform: All OS/Version: Other Status: UNCONFIRMED Severity: critical Priority: low Component: TCP/IP AssignedTo: unassigned@bugs.ecos.sourceware.org ReportedBy: kenkyee@excite.com CC: ecos-bugs@ecos.sourceware.org Class: Advice Request Our application requires that we make multiple PPP connections to minimize connection costs, so we have a pretty simple core bit of code that brings the PPP line up and down. Sometimes, eCos will hang during the cyg_ppp_up or cyg_ppp_wait_up calls. The only thing that shows up in the diag console is: SYSLOG 08: Using interface ppp0 SYSLOG 04: Connect: ppp0 <--> /dev/ser0 SYSLOG 08: Connect time expired SYSLOG 04: Connection terminated, connected for 1 minutes The core loop is roughly like this: cyg_ppp_handle_t pppHandle = cyg_ppp_up(PPP_PORT, &options) if (pppHandle != 0) { int pppStatus = cyg_ppp_wait_up(pppHandle); if (pppStatus == 0) { // wait for connection to come down if (cyg_ppp_wait_up(pppHandle) == 0) { int pppTimeout = PPPMAXUPTIMESECS; // PPP timeout in seconds while ((pppTimeout-- > 0) && (cyg_ppp_wait_up(pppHandle) == 0)) { Thread::sleep(sec(1)); } cyg_ppp_down(pppHandle); } } -- 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.
