Re: [Ltib] Re: GDB with a JTAG

[Charles Krinke]

Morning.

In working through getting a BDI-2000 to step through the linux kernel with ddd/gdb, I've gotten to where I can do:

$ ddd --debugger powerpc-e300c3-linux-gdb vmlinux
(gdb) target remote bdi:2001

At this point the source window for head_32.S is loaded by ddd *and* a "continue" lets the kernel boot.

I have changed the source search path from the default to the linux kernel source within ltib, but when I try to open source from within ddd, I get the choice of only a couple of .S files, that is, head_32.S & entry_32.S.

Can someone offer and idea so I can get to where I can step from the first C line in the kernel (or any C line), such as setup_arch()??

All right. I compiled gdb and have a valid executable per the application note, but, ... when I connect to the BDI with "target remote bdi:2001", I get a connection refused or a timeout.

IIRC, try "target remote bdi:3001", assuming "bdi" maps to the IP address of your BDI...

Would anyone have a suggestion at this point?

I am convinced there is some law of the universe that declares "after krinke embarrasses himself in public, he will be allowed to see the answer". So, after a little research, it appears the answer is:

"Read http://www.ultsol.com/pdfs/ToolTalk_03-001.pdf and the recipe of cross compiling gdb and connecting to a BDI-2000 is revealed."

<sigh>
