Wolfgang,

>From the AgileDB product data sheet (I can send it to you if
you'd like), it is clearly a GUI front end for GDB, or any
other debugger you want to use.  They allow you to issue any
GDB (or any tool's) command-line command from a prompt, if
that's what you're familiar with.  From their data sheet:

Channels and Connections
------------------------
AgileDB communicates to any number of debug devices or tools
using Connections and Channels.

Connections are physical connections to devices, tools or
target services.  Channels are logical paths across a
connection.  Examples of some typical tools and services you
can connect to AgileDB:

* The BDI 2000 ICE Command Set
* The GDB Command Set
* Target Serial I/O (over telnet)
* Any Tool or Service that uses Telnet
* Boot Agents Like: PPC/U-BOOT
* User-Defined Tests and Target Services

Theoretically, you're supposed to have productivity gains
by using their GUI (if you invest the time to learn it, just
as you've invested time to learn a CLI) over the equivalent
CLI way of doing it.  Their "claim to fame" is that they've
solved the "window-explosion" problem that most GUI
debuggers suffer from.  In a particular debug session, you
can put all of the things that are most important to you
into a single window.  I have no idea if this enhances
productivity, but I know that one of the reasons that I
prefer CLIs is that I spend more time opening, closing,
re-sizing, and just plain fiddling with the GUI windows.

If it were up to me, I'd just use the CLI.  But I work for
a company that has to consider the productivity of engineers
whom they're paying to train.  If they train them on a CLI,
and their productivity is not as good as if they had trained
them on a GUI, then they are not helping the company.

(And I'd like to keep my job ;)

Thanks, I've read it.

This is why I wonder what they provide which  is  not  available  for
example  in  DDD,  which is available for free and pre-installed with
all major Linux distributions.

> * The BDI 2000 ICE Command Set

available with DDD/GDB though GDB's "monitor" command

> * The GDB Command Set

available through GDB itself.

Yeah, all available without AgileDB, too.

You can use DDD if you want a GUI.

As mentioned before, you will have to test yoursdelf if you like  the
tool,  or  not.  But do yourself a favour and test DDD, too. And then
compare the prices.

Need opinions: Porting PPC linux for a custom Prep board.

[dong in kang]

 Hello,

 I'm trying to port MontaVista Linux for a custom Prep board.
The CPU is a variant of IBM PPC750, and the PCI bridge chip is a variant of
MPC106.
The architecture of the CPU is same as IBM PPC750.
The architecture of the bdidge chip is a superset of MPC106.
Any suggestion which code should I start with?

 I found some prep specific routines under arch/ppc/platform directory.
The codes seem to work for two targets, IBM prep and Motorolla prep.
If I had better start with one of them, which would be better?

 Thank you,

 Dong-In
