[ECOS] difference between gdb and insight

[ECOS] difference between gdb and insight

[Arnaud Mouiche]

hello

in there a differences in the way GDB and Insight can use JEENI embedded 
ice for debugging ARM code.
In fact, I use Insight at this time. I still don't try simply GDB. I 
experience some problemes of code downloading and break points, even with 
'set rdiromatzero 1' command.
Is there any other things I should know ?

No, in fact insight is just a use interface on top of GDB. If you start it
with the -nw option you will get a regular gdb prompt.

Beside from the obvious stuff (what is your target, where should your program
be loaded) there is not to much to take care off.
However, it might be that your platform needs some initialisation before you
are able to use your RAM memory (my system contains a device controller that
needs to be programmed with the correct memory with and delay cycles before it
can be used).

You might try to use the "x <address>" and "set *<address>=<data>" to see if
you are able to write to and read from your memory.

Good luck,
