Hi Andrea,

I think you have successfully installed AEB 1. I just need some help
regarding the installation. I too am following the  instructions as given in
"Getting started with eCos" in the section "ARM AEB 1 hardware setup"
The steps i followed so far is given below:

As you can see, i donot see the ecos stub loaded in the flash. Am i doing
something wrong?
Can you please help me out?

Yes, you did not use the flashwrite command. Please follow the
instructions to the letter.

Hi Jonathan,

I found that the gdb-stub module for the AEB rev.C, provided with eCos,
doesn't work at 9600 baud.

In addition, when I tryed at 38400 baud, the connection failed because the
serial port configuration that I made on the
AEB board was not correct. In effect, two environnement variables must be set
to change the baud rate properly,
that is, you have to give the following commands at the prompt of the
bootstrap loader:

boot: setenv baud 38400
boot: setenv noautobaud

With this settings, everything seems to work correctly. (Also if I don't see
the output string ++$T01... that you
mentioned, when connecting the board directly to minicom, or other terminal).

Andrea.

Is your fix something particular to your configuration, or something that
we need to fix here (if so what?).

Hi Andreas,

Thanks a lot for your reply.

I fixed the problem.
It was in the serial port configuration in the AEB board.

RE: [ECOS] Hello world on AEB rev.C

[Andreas.Karlsson]

Well I'm running windows NT on that machine so I use a Hyperterminal with
baud rate 38400. But I have done it with the prompt too:

arm-elf-gdb \x13 nw 

(gdb) set remotebaud 38400    

(gdb) target remote COM1



When using Hyperterminal I do it like this.

download c000 

(then I go to the location of the image
"eCos/loaders/arm-aeb/gdb_module-revC.img)

When the download is completed and a message tells you how many bytes that
was downloaded.

flashwrite 4018000 c000 8000

plugin eCos

NOTE: The command (gdb) set mips-force-32bit-saved-gpregs should not be
used.



Then I invoke insight, arm-elf-gdb my_prog&, in which I use 'run->download'
target=Remote/serial and baudrate=38400.

No, just close the connection and download your program.

Don't think so. I have been trying building new modules for 3 weeks and my
only test was if I could connect or not...

I have never seen any such output.

No idea.

I actually wrote some notes how to get the hello world example running, here
it is:

----------------------------------------------------------------------------
------------

After installing the stub eCos has to be built matching your processor
(AEB-1). This is done in the Configuration Tool (Program->Red Hat eCos->
Configuration Tool). The procedure is given in \x1c Configuring and Building
eCos from Source 64\x1d . Don't forget to select revC.



Your first program is compiled using this command e.g. 

bash.exe-2.04$ arm-elf-gcc -g -I/d/ecos-work/myeCos_install/include hello.c
-L/

d/ecos-work/myeCos_install/lib -Ttarget.ld -nostdlib

The executable program will be called a.out. If you prefer some other name
add the option \x13 o my_own_name.

The commands to run the program look like this.



Alternative 1 \x13  prompt

Continuing.

NOTE: Make sure the paths don\x19 t contain any spaces.



Alternative 2 \x13  graphical



bash.exe-2.04$ arm-elf-gdb a.out &



This command invokes the graphical Insight-debugger. To run your program
through this interface just select \x18 Run\x19 . First you will be prompted to
select which target you want to connect to, select \x18 Remote/Serial\x19  and
press ok, then you can see when your code being downloaded to the board.



Good luck

Hi,

this is the output I find when I power on the board (using minicom) under Linux
OS:

.í.cä
ARM Evaluation Board Boot Monitor 1.01 (18 NOV 1999)
Press ENTER within 2 seconds to stop autoboot

  Found module 'eCos' at 0401ba6c
Boot:

I followed the instruction in "Getting started with eCos", section "ARM AEB-1
Hardware Setup".

I don't see the string you mentioned. In addition, I don't understand the meaning
of the
first sequence of characters.

Have you any idea about the problem?

You mean downloaded as in programmed in flash right?

If you just connect with a direct serial connection, when you power on the
board you should be able to see output like ++$T01.....

If not, then the gdb stub is not programmed onto the board correctly.

Hi,

I downloaded the prebuilt version of the gdb-stub (gdb_module-revC.img,version
1.2.2) ,
but after the connection with the target (set to remote/serial, 9600 baud),
I'm not able to dowload
the hello executable (the download command has no visible effect).

What's the problem?

You cannot use RAM-loaded eCos applications under Angel. Instead you should
reprogram the board with GDB stubs. This is described in the Getting
Started documentation.

[ECOS]Hello World on AEB rev.C

[Andrea Acquaviva]

Hi,

I followed the instructions on the manuals to build eCos for AEB revC
board and
link it with the Hello World example, but when I start with the
debugging after
the download, the "insight" debugger crashes.  I use Angel as a debug
monitor in the target board.
The steps I made to build eCos for AEB are the followings:

- ecosconfig new aeb
- in the ecos.ecc file I set the user_value in the
CYGHWR_HAL_ARM_AEB_REVISION option
    section to "C".
- in the same file I set the user_value in the CYG_HAL_STARTUP option
section to "RAM".
- ecosconfig tree
- make

Are there some settings that I need to be aware to keep executables
working on
the AEB board with Angel remote debug monitor?
