[ptxdist] Ptxdist menu config -> GDBServer

[-- Attachment #1.1: Type: text/plain, Size: 618 bytes --]

Hi everyone

Got a question. I followed the quickstart doc for the newest bsp 2012.12.0
and built everything, ptxdist, toolchain and the rootfilesystem. everything
works great, boot via nfs etc...

now i want to start developing some neat apps using qt creator. It seeems i
missed something, I have no gdbserver on my mini2440. Playing around with
ptxdist menuconfig, i saw there is a gdbserver option, i suppose this is
where i enable it. the only thing thats bugging my is, do i have to re
build everything now and reinstall ptxdist, or is there some short cut i
can take?

Thank you in advanced

Regards
Ruben Louw

This option is project centric. Just enabled the GDB option in the menu of 
this project and run the "ptxdist go" in the BSP directory again. After that 
everything is in place. Now it depends on your usecase how to proceed. If you 
are using NFS root and you have exported the "platform-mini2440/root" 
directory you are done. If you are using your Mini2440's NAND you need the 
additional "ptxdist images" step and to store the updated jffs2-image into 
the NAND again to get gdbserver into your Mini2440.

Juergen

Hi Juergen

I executed ptxdist go but I received an error, I attatched the terminal log
file. I copied from more or less where i could see the first error occured.
Not sure what its complaining about, looks like somthing in gdb itself.

any advice is appreciated, thank you.

Hi Ruben,

please keep the mailing list at least on CC.

Same here, when I enable the gdbserver.

The default setting of gdb-7.2 is too old for Linux 3.7. Use a more recent 
one. With the OSELAS.Toolchain-2012.12 comes the gdb-7.5 at the host side. 
So, run

 1) ptxdist clean gdbserver
 2) ptxdist menuconfig

and change:

Debug Tools --->
       gdb --->
           (7.5) gdb version
           (24a6779a9fe0260667710de1b082ef61) gdb source md5sum

 3) ptxdist go

Should work now.

Regards,
Juergen

Sorry bout that, gmail doesnt add the cc i hvw to do it myself. I also
enabled the gdbserver, and rebuilding. Do you have any tips on how to debug
with qt creator and setting up the compiler for the mini2440?

You BSP will definitely help, havent had time to read the ptxdist guru doc,
but i will, as soon as i get this going.

Thanks

Ruben

Hmm, I think you should develop your Qt4 application on your host first. You 
have access to all little helpers you need in this case.

And when the application does its job perfectly, just cross compile it again 
with PTXdist for the Mini2440.

But sorry, I'm a kernel hacker, not a Qt expert.

Regads,
Juergen
