2:Insight not knowing about execuded gdb.ini commands!

[Roman <maillists at gmx dot ch>]

Sorry, there are no screenshots allowed in the mails. Therefore the 
first mail is not really understandable. Here a second try.

Hi everyone,

I am programming a NetSilicon ARM7 processor using Microcross Visual
X-Tools 2.2 which include
cygwin 1.2, gcc 2.95.x, Insight/gdbtk 4.18i, OCDLibRemote for
Macraigor-Raven JTAG.

I know that the toolchain is quite old, but for the moment I am bound to it.
Actually these issues are mainly about convenience.

1)
If I start gdbtk without passing the gdb.ini file as command line
argument I will have to click a bunch of button once gdbtk is up
( connecting to the remote server via TCP, loading the gdb.ini file
manually, downloading the programm) to get ready to debug.
If I pass the gdb.ini file as command line argument, I am able to make
gdbtk to connect and download automatically. gdbtk then is ready to debug.
Once I want to restart (run button), gdbtk opens the connect dialog,
probably because the GUI did not recognize that we are connected already.

How can I make gdbtk realize what is executed in the gdb.ini file
(please see the script files at the end of the email)?


2) In the gdb.ini file I change the read write packet sizes in order to
speed up download, which actually works fine, if where was not this
warning window I have to confirm all the time.
I tried several different packet sizes.

Warning window message:
<
This target my not be able to correctly handle a 
memory-write-packet-size of 1024 bytes. Change the packet size?
Yes /No?
>

Has anyone an idea how get rid of that?

3) The run button in gdbtk does not work, even though I connected
manually to the remote server (not the same problem as 1) ). So I tried
the console within gdbtk
 and typed the run command and got the following result.

Console window:
<
Breakpoint 1, BootSytemUp() at ./../../Global/Bootc:206
(netsilicon-gdb) run
Starting program: 
/cygdrive/d/Daten/MicrocrossARM7/APP_TrxIface/C_Prj/Global/TrxIface32b/image.elf
>


Warning window message:
<
The program being debugged has been started already. Start it from the
beginning? Yes /No ?
>

After pressing Yes..

Console window:
<
Error You can't do that without a process to debug.

(netSilicon-gdb)
>



So how does gdb(tk) know what to run the first time and when I try to
restart it after breaking somewhere in the code it does not?
I assume that the none working RUN-button in the GUI and the error
message in the console have the same cause.

How to fix this?


All the button clicking in issue 1) was not  that bad, if had not to
quit and restart gdbtk everytime I need to start the program debugged
from the beginning.


I would appreciate some hints on that issues. Thanks!!


Regards

Roman
