[U-Boot] U-boot debugger/emulator

[Steven Zedeck]

Hi,
This question is related to U-boot; in particular debugging in a U-boot
environment.

I am working on U-boot for the first time as well as working with the Atmel
AT91SAM9 processor. I am used to working with emulators when debugging low
level code such as embedded diagnostics.

I've never used the Atmel till now. In the past, I've worked with many
PowerPCs, Freescale, and Microchip processors. All have had various
emulators such as Microchip's ICD2, and with PowerPC I've used VisionClick,
CodeTap, etc.

Can anyone suggest a good JTAG-based emulator with a good Windows or
Linux-based debugger? Microchip's tools were very inexpensive and pretty
powerful. PowerPC's were a bit more expensive. I need something where I can
build U-boot with its makefiles, that we all know and love, load the code
into flash and/or ram, set breakpoints, single-step, look at variables, look
at C-source code, registers, possibly an IDE/editor, etc.

Any suggestions?
Thanks,
Steve

You will have 2 good ICE with multiple ARCH support
PEEDI from Ronetix (with dataflash, NAND and OneNAND support I'll recommand
for AT91)

or BDI3000 from Abatron

The both work well on MacOS, Linux and Windows

Hi,
This looks very good. I have a couple of questions. I see on their web site
that they offer a product called bdiRDI which allows you to use a source
level debugger. I didn't see that they sell any source level debugger. What
do you folks use as a source level debugger? Cost is an issue, however, I
don't want to sacrifice quality and features too much.

Did you purchase or obtain your source debugging application elsewhere? Or
do you use GDB? I haven't use that before. I'm used to a source level
debugger I believe.

thanks,
Steve

As already mentioned, we too strongly recommend the BDI3000 by
Abatron. It fits perfectly into a GNU toolchain based development
environment, has full MMU support (which is essential when it comes to
Linux kernel debugging) and supports a wide range of embedded
processors - ARM, PowerPC, MIPS, ColdFire, ...

You want the bundle BDI3000 with firmware bdiGDB - interface firmware
for GNU debugger.

So what do you think GDB is? It is one of the most powerful source
level debuggers that are available.

I see that this bundle is $2640US which is beyond my budget. I need to find
another approach.
Debugging with printfs is starting to bother me and waste time.

Also, I am not totally familiar with GDB (GNU debugger). I may need to read
a bit about it.
thanks,
Steve

PEEDI is $2080US

but all real ICE will be near

In my last position where we used Microchip processors, I was able to get the
Microchip ICD2 JTAG probe/emulator for less than $200 and the windows-based
debugger software was free; all from Microchip  I must be spoiled.

Thanks,
Steve

It's for small micro-controller not ARM9
It's not comparable to a generic ICE which can be updated to support CORTEX
A8, PPC, MIPS, etc...

If you are looking for a GUI _on top_ of the source level debugger, you
have also a few options.  Our TWiki gives an example[1] on using the
quite attractive ddd[2].

I agree that a generic solution is better, but....
We use the Abatron BDI3000 for our current project (using the bdiGDB firmware
for the MPC5xx/8xx). If we want to use this JTAG/BDM with, say an ARM processor,
we must pay Abatron appox. half the price of a new BDI when switching firmware.
I think the cost here eats up the advantage of having a generic product.

Frank

You work with Steven Zedeck?
If you already have a BDI3000 you will just have to buy the ARM7/9 FW arroud
950? IIRC

Um... not really. Normally the price for the firmware alone  is  less
than 40% of the price for the bundle BDI3000 with firmware.

> I think the cost here eats up the advantage of having a generic product.

Well, with hardware-specific products you always have to pay the full
price. That's even worse. And probably your interfaces (including the
user interface) are changing, too.

No. I just had an opinion regarding the BDI.

I've already got it, not Mr. Zedeck.. I think 950? is "a lot" for just
the firmware. They've got 6 different
bdiGDB versions just for the PPC architecture. I feel that it's wrong
to use the term generic when
you must pay 950? and flash the firmware for each new target. But
don't get me wrong though, the BDI
rocks!

Btw, is any of you guys using the self-made MPCBDM? I'd like to use it
on 82xx or 83xx, if possible.

Frank

Ok, I exaggerated. We payed 2500$ including firmware worth 950. That's 38%.

Most often yes, but how much interface changes regarding BDM communcation
is there between, say 8xx and 82xx? I'm sure you know the exact details ;-)

We used to use (and even sell) those.  The  can  only  be  used  with
MPC5xx/8xx systems which have a BDM interface; 82xx, 83xx etc. have a
JTAG  based  COP  interface  for  which  no specification is publicly
available (you can get it by signing a NDA, but the NDA terms prevent
you from implementing support for this in Open Source software).
