Re: Insight crashes when I open a located image

Re: Insight crashes when I open a located image

[Gerwyn Davies]

These are the command lines I'm using. Its only a simple program to flash an
LED:-

mips-tx39-elf-gcc -O2  -DCOSMP27 -DCIO_27 -D__BigEndian -DB115Kext -O2 -g -W
all -fno-exceptions -DUSE_HELP -DNO_MALLOC  -c led.c -o led.o

mips-tx39-elf-ld -o led.out -lg -lstdc++ -L/lib -T/link/tx39xxb.ld -Map
led.map crt0_only.o led.o


I've tried using gdb -nw, but I have a very hard time trying to connect to
the target. Here's a trace:-

>Remote debugging using com1
>Sending packet: $Hc-1#09...putpkt: Junk:

Nothing will happen, until I press the NMI button, then on rare occaisions I
can connect. I don't have this problem when using Insight, but I do still
have to press the NMI once before I can connect to the board.

The diference is that Insight (the GUI) always send a "set remotebaud NNNN" before
the "Target" command.

Please try the sequence:

set remotebaud 9600     (or whatever your board speed is)
target remote com1      (I am assuming your board monitor has a gdb remote stub, 'course)

What is the exact command line you've used to compile/link your application?

The Help menu has the About option.  That will tell you something.

For the problems you are refering to, you can also start gdb with the
command line interface:

gdb -nw

It will print the underlying debugger version.

Insight crashes when I open a located image

[Gerwyn Davies]

(No HTML this time I hope!)

Hello,

I have a problem where Insight crashes out when  I open an linked and
located object file, and was hoping that someone may be able to shed some
light onto it.

I'm using:-
>GNU gdb 4.17-gnupro-98r2
>This GDB was configured as
"--host=i586-pc-cygwin32 --target=mips-tx39-elf".
I dont know what version of Insight I'm using, maybe someone could tell me
how to find this out.

I've taken a look at the object file with objdump and can't see anything
wrong with it. If I open a compiled object, Insight is happy. I know what
you're going to say:- "Try it with GDB 5.0!", but I only want to use GDB 5.0
if I have to.


Many thanks.

Gerwyn
