Re: [lwip-users] Assertion - tcp_receieve: valid queue length

[陳 小擁]

hi .

i meet the same problem . it am using LwIP 1.0 without OS . when i try to send some data form my platform to the PC . however , when i using tcp_write() . I can't get any data in the PC . and it will print the Assertion like that :

Assertion -- tcp_enquene : valid queue length .

after read the mail-list . i use tcp_output() after the tcp_write();

 

>err = tcp_write(temp_pcb , &abc[j] , sizeof(abc[j]),0) ;
>     tcp_output(temp_pcb) ;

after that , it will print :

Assertion -- tcp_receieve : valid queue length . i can't come up with it . can some tell me how to send data in tcp_write without OS ?
