Hello all, Thought will share this to the list :-)
Note: The blog was written based on LDTPv1 Debugging ldtp over net from 2 PCs (XP & Ubuntu) (2010-09-28 18:44:44) 转载 标签： 杂谈<http://uni.sina.com.cn/c.php?t=blog&k=%D4%D3%CC%B8&ts=bpost&stype=tag> 分类： ldtp <http://blog.sina.com.cn/s/articlelist_1607919532_3_1.html> The working PC I'm using usually is under Windows Box, and the device (arm target that running ldtp) is connected to this pc over USB. However, ldtp source code is compiled under Ubuntu(scratchbox), and I could not find a porting gdb which is working under Windows(I tired to use cygwin gdb, but failed to communicate device). I had to transfer to Ubuntu, that's not good. One reason is that I don't like the fonts Linux offered, I never get a stylish font in gedit. And I have set an X11 forward feature from putty so that I can control the simulator (x86 target) under Window XP, pretty much pro[image: Debugging <wbr>ldtp <wbr>over <wbr>net <wbr>from <wbr>2 <wbr>PCs <wbr>(XP <wbr>& <wbr>Ubuntu)] . Lucky, I have find a way to debug it under XP today, that's why I write to here, hope it will help other if they never tried this, see picture below for my target: [image: Debugging <wbr>ldtp <wbr>over <wbr>net <wbr>from <wbr>2 <wbr>PCs <wbr>(XP <wbr>& <wbr>Ubuntu)]<http://photo.blog.sina.com.cn/showpic.html#blogid=5fd6e7ac0100lxmi&url=http://static6.photo.sina.com.cn/orignal/5fd6e7acn914ffc30e645> Both XP and Uubunut is running a port [ *2345* ]forward server, rinetd, the config should be like this: Window XP, forward the data to my device: # bindadress bindport connectaddress connectport 0.0.0.0 2345 172.22.3.1 2345 Ubuntu, forward the data to remote server: # bindadress bindport connectaddress connectport 0.0.0.0 2345 192.168.3.1 2345 Yes, I have SSH server on Ubuntu, so that I can control from XP(for X86 as well). So, after login into device, I issue to create a gdbserver listener: /var/opt/home # gdbserver :2345 /usr/bin/ldtp -s Process /usr/bin/ldtp created; pid = 1345 Listening on port 2345 Then connect by to that port: $:)gdb /usr/local/bin/ldtp No symbol table is loaded. Use the "file" command. (gdb) target remote 127.0.0.1:2345 Remote debugging using 127.0.0.1:2345 [New Thread 1345] 0x410007d0 in ?? () (gdb) b main Breakpoint 1 at 0xcda8: file ldtp.c, line 473. That's done, Good enough[image: Debugging <wbr>ldtp <wbr>over <wbr>net <wbr>from <wbr>2 <wbr>PCs <wbr>(XP <wbr>& <wbr>Ubuntu)] . PS. Actually I made a porting ldtp.py that can be run under Window XP too(just copy/paste), so that I can demonstrate ldtp to my colleagues only a XP.

I like this way :) http://blog.sina.com.cn/s/blog_5fd6e7ac0100lxmi.html Best Regards, Lavi (Guofu Xu) =================================== Mp: 86-13951875404 MSN: lav...@hotmail.com Yahoo: lav...@yahoo.com G-Mail: lav...@gmail.com -- Linux Desktop (GUI Application) Testing Project - http://ldtp.freedesktop.org http://nagappanal.blogspot.com
