What do people recommend for a JTAG emulator for the MPC8548E =

(version 2 silicon).

We are not built (or want to) to work with Code Warrior =

environment – thus we can't use the ones that came with =

our CDS.

Important (or nice to have) = features:

network capable (easy remote = debug)

kgdb compatible (easy kernel remote = debug)

gdb server compatible (for user level remote = debug)...

Ideas?

Thanks in advance.

Just to add my 2 cents, I had problems with the BDI-2000 as well. The unit I got from Abatron had a hardware problem (the ethernet controller would sometimes reset when the BDI initialised the target PPC processor). Their French distributor agreed to replace it after making sure it was indeed a hardware issue (they seem to assume end-users have a negative IQ and are unable to diagnose such a hardware problem themselves). The new unit works *mostly* fine. No debugging issue (not that I use it that much anyway, now that the board boots Linux), but still a flash programming issue. Programming the target parallel NOR flash works in slow JTAG mode, but not in faster mode using the internal workspace. I reported the problem several months ago and still haven't received any solution. It might not be Abatron's fault, the French distributor might not have reported the problem to them. Abatron people speak German only, and will not respond to e-mails written in English (nor will they talk to you on the phone, they just hang up). The BDI-2000 is a nice product, but has a few bugs, is IMHO overprized and has one of the worst support service I've had to deal with.

Depending on the particular chip model, to be able use workspace you must have initialized memory first. In fact, I'm pretty sure you haven't configured chip correctly to make workspace usable. I've been using BDI with various PowerPC and MIPS SoCs for many years. It's an excellent tool, you just have to use it correctly. -- Eugene From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from outmx015.isp.belgacom.be (outmx015.isp.belgacom.be [195.238.4.87]) (using TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)) (Client did not present a certificate) by ozlabs.org (Postfix) with ESMTP id 6EEE3DDEC4 for ; Wed, 24 Jan 2007 22:06:31 +1100 (EST) Received: from outmx015.isp.belgacom.be (localhost [127.0.0.1]) by outmx015.isp.belgacom.be (8.12.11.20060308/8.12.11/Skynet-OUT-2.22) with ESMTP id l0OB6PME019578 for ; Wed, 24 Jan 2007 12:06:25 +0100 (envelope-from ) From: Laurent Pinchart To: Eugene Surovegin Subject: Re: JTAG emulator for MPC8548E (v2) Date: Wed, 24 Jan 2007 12:06:17 +0100 References: <200701240857.19428.laurent.pinchart@technotrade.biz> <20070124103548.GA31703@gate.ebshome.net> In-Reply-To: <20070124103548.GA31703@gate.ebshome.net> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Message-Id: <200701241206.18167.laurent.pinchart@technotrade.biz> Cc: "Morrison, Tom" , linuxppc-embedded@ozlabs.org List-Id: Linux on Embedded PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hi Eugene, > > The new unit works *mostly* fine.

It is probably a target processor configuration issue, as I can use the workspace if a) the target flash has already been programmed with U-Boot b) the BDI-2000 is misconfigured and fails to stop the target processor at startup. I can thus use the workspace when U-Boot initializes the processor. I had a look at U-Boot code and tried to initialize the processor registers with the same values, without luck. I asked Abatron's French distributor for technical support, and they haven't been able to help me. They made me try lots of different initialization sequences. Several people online sent me their configuration file, and none of them worked for me. So, there must be a configuration problem somewhere, but even Abatron's technical support haven't been able to find it. That's why I complained about their support in my e-mail.

Also, back when my company bought a bunch of BDI's they were around half the price of the nearest competitor and less cumbersome to use. Maybe there are cheaper alternatives now, I don't know. Obviously, YMMV.

I've owned one of their units for several years, bought it with my own money (which says a lot, since I'm a freelancer!). And I've brought a few obscure issues to them over the years, all of which were addressed to my satisfaction. The BDI2000 has been solid, significantly easier to setup and more reliable in use than several other systems I've tried. One thing to keep in mind is that they're really constrained by not having intimate knowledge of _your_ platform. If your memory bus configuration is wrong, for example, there isn't a whole lot that they can do to rule that out from their end since they don't have your hardware. JTAG in general gets easily tripped up with power problems, etc. that are a natural part of untested circuits. If this stuff was easy, we'd have to find work elsewhere! >And no, I don't get a kickback from them... :) > > Me neither. But if someone from Abatron has an unused unit sitting around, I sure could use one! :) b.g. -- Bill Gatliff bgat@billgatliff.com From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from mail-out.m-online.net (mail-out.m-online.net [212.18.0.9]) by ozlabs.org (Postfix) with ESMTP id CFD09DDF36 for ; Thu, 25 Jan 2007 07:49:46 +1100 (EST) To: Laurent Pinchart From: Wolfgang Denk Subject: Re: JTAG emulator for MPC8548E (v2) Mime-version: 1.0 Content-type: text/plain; charset=ISO-8859-1 In-reply-to: Your message of "Wed, 24 Jan 2007 08:57:19 +0100." <200701240857.19428.laurent.pinchart@technotrade.biz> Date: Wed, 24 Jan 2007 21:49:44 +0100 Sender: wd@denx.de Message-Id: <20070124204944.172BB353BC5@atlas.denx.de> Cc: "Morrison, Tom" , linuxppc-embedded@ozlabs.org List-Id: Linux on Embedded PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , In message <200701240857.19428.laurent.pinchart@technotrade.biz> you wrote: > > The new unit works *mostly* fine.

I agree with you there, but I haven't been able to find which setting I got wrong. I dumped the registers contents after the board gets initialised by U-Boot, and all related values are identical. I even traced the U-Boot code and tried to reproduce the exact initialisation sequence, without luck. This is definitely an initialisation issue, as programming in workspace mode works when the board gets initialised by U-Boot first (wrong reset vector setting in the config file, which makes the BDI freeze the processor after it started up). > > several months ago and still haven't received any solution.

So it all was just a FUD, how low. I don't agree with you there. It is a configuration issue related to the BDI. For all I know, it could be a bug in the BDI that only occurs when initialising given registers in a given sequence. Or it might be an issue with the BDI-2000 unit I got, which might have a hardware problem. I blamed my configuration file first, but even the tech support people haven't been able to locate the issue. All I know is that U-Boot is able to initialise the processor correctly, but the BDI isn't, even when fed with a configuration file that performs the same initialisation sequence as U-Boot. There are two possible causes : either I got the configuration file wrong and forgot a setting, or the BDI fails to perform one of the steps correctly. > > I had a look at U-Boot code and tried to initialize the processor > > registers with the same values, without luck.

I just wish I hadn't suffered such a bad technical support experience. That's probably the French distributor's fault, and it seems I have been very unlucky when contacting Abatron directly.

I'm working on a proper patch to add all of this formally to the sources. It's been irritating me for a long time, so I'm reworking some of these jtag debugger options. Unfortunately, it touches more than just 85xx to get it right. Thanks. -- Dan
