Re: [lwip-users] problem of rtl-lwip!

[Sergio Pérez]

Hi, liu kun!!

First, If you're using a 2.4.18 kernel the bigphysarea patch that you should use
is the 2.4.0.
http://www.polyware.nl/~middelink/patch/bigphysarea-2.4.0.tar.gz

Also, if you read the section "requirements" in the RTL-lwIP home page 
http://www.rtlinux-gpl.org/~serpeal/RTL-lwIP/htmlFiles/

you'll see that RTL-lwIP needs POSIX signals and Timers from the RTLinux
distribution, so you need to compile RTLinux with those options checked.

In the FAQ section you can read how to configure bigphysarea and how to check if
it has been installed properly. Bigphysarea is also a requirement for the
dynamic memory allocator to work.

If you have any problem please contact me: serpeal_AT_disca_DOT_upv_DOT_es

Best regards.

Sergio.
