[oe] How can I use gdb in oe?

[Mats Kärrman]

Hi,

Assuming that you mean to debug programs on your target...

Prerequisites:
- a network connection between your target and your development host (it's possible to use a tty too).
- OE built SDK installed on your host.
- gdbserver package installed on your target.
- your binary (my-program) on target
- an unstripped version of your binary in the working directory on host.

The exact commands below will vary with the install path of your SDK (/usr/local/oecore-x86_64 in my case)
and target specifics (e.g. powerpc, ppce300c3... in my case).

On target:
# gdbserver :2345 my-program

On host:
$ source /usr/local/oecore-x86_64/environment-setup-ppce300c3-oe-linux
$ powerpc-oe-linux-gdb my-program
(gdb) set sysroot /usr/local/oecore-x86_64/sysroots/ppce300c3-oe-linux
(gdb) target remote <target-ip>:2345
(gdb) br main
(gdb) cont
...

Good Luck!
// Mats

Subject: [oe] How can I use gdb in oe?

Hello,

I use open-embedded in my company.
It is used in Qualcomm's communication module - specifically on AP
(Qualcomm's chipset is composed of MDM + AP).

And when I compile oe linux, I use bitbake.

In this environment I'd like to use gdb to debug applications for this oe
linux.

How can I use gdb in this?
I have experience in using gdb in just PC environment. Not in embedded env..

Thank you very much in advance!

Sincerely
Journeyer
