I know that the BDI2000 works fine, and some people have been successfully using the vision* tools, too (often after some struggeling). My personal tool of choice is the BDi2000. Use the tool you know best... And yes, single stepping is possible if your tool allows it.

Subject: u-boot = debugging

 

Hi,

 

Which tool must i use to debuggin u-boot codes. = BDI2000 or windriver visionclick, which one do you prefer? is step by step code = tracing possible?

 

thanks

Yeah this thread is covering a broad range of JTAG debug. There
are debuggers that range form $50 to $50k with no JTAG standard. 
$50 wigglers that are painfully slow because they bit-bang the parallel
port and $50k Gigabit interface with GBs of fast memory that can "capture
bugs" in realtime (that is if you can define/setup the trigger condition to
capture "the bug", but for a 400MHz processor that may only mean 1-2

single step, breakpointing, etc, but the coolness is the capability to run

part is no need for windose and with DENX you don't have to pay big
$ to metrowerks, greenhills or the like and wait while they develop or
if they will ever develop debugger software for your target!
You should really get a clue. Or can you please explain what  is  the
maximum  transfer rate you can get over the BDM / JTAG interface, and
how is this limited by the 10Mbps Ethernet interface?

Well, I suppose using a 10Mbps switch shouldn't cost much more than a 100Mbps hub, and you almost said it yourself, that it would be more efficient in a crowded network ;-) What I really wonder is what the choice between a switch and a hub has to do with "global technology trends". I detect an increasing amount of resentment in your words, and that is not good as far as my experience goes.

This is true... I have had quite a few bad experiences with open source product. e.g. RH 6.2 the loop back driver would flush data to the driver every second time. People at work would change compiler, graphic settings on me... Swap ln commnad options.... crack linux md5 passwords... break gid/uid settings... steal my linux CD roms... This happened to me at my ex-employer for about 2.5 years for sure... 6 years in total (on my windows box with USB scanner, printers, boot sector crashes, file/pdf corruption... Besides the usual of getting SPAM, virus, trojans etc... The latter is okay but the rest is strange... ). Now when you are on a schedule deadline, how many bugs can one fix... Code which runs on one day does not on another day... Its like somebody (internally) is trying to sabotage my project or changing code without knowing what they are doing... They could be doing this just to get rid of me either (which I dont know ) as I dont know *who*. In the past, I used to just take my network cable off and not be bothered with personal backups but on a shared network with clearcase I cant go offline. Cannot upgrade from 9.0 to Fedora... Each day, there are different problems with the machine... So, this is the prime basis of resentment in my words. Its kind of happening again. There are routines in u-boot e.g. cpu_post_exec_02 and cpu_post_exec_04 which use a stackless approach to copy a function to a given address, execute them and pass the values back to the calling app. It was working the other day and now its not. I test the first instruction it has to execute and it was supposed to be 0x38000000 and it shows as 0x38000331. I mentioned it to my peer and next day its different. I dont like hidden resources on my project but dont know if I should ask ? If its by design or by coincidence... Generally hidden resources(unless very skilled & dillignet) cause more harm than help... I am not sure about gdb protocol support for Metrowerks but it should be an easy extension. Just like changing the Phy on BDI should be easy change. Not sure if it has a FPGA or ASIC or some controller driving the JTAG chain. JTAG on BDI (is probably 12 or 16MHz) so its faster than a 10Mbps ethernet link. They were just saving cost as JTAG chain address/data cycles are long so one wont get a full 10MHz data transfer. JTAG by itself can go to 40MHz so, the next rev of BDI can go with a faster JTAG chain and 100Mbps link or a USB link. Advantages of Metwerks so far : 1. Comes with the reference board from Freescale with 1 month license. 2. I did not get any help from BDI to setup the config file for 870/885 processor. 3. BDI did not program the AMD 29F style flash part. 4. BDI does not program the micro IC chip on Xscale. If one wants to debug loadable modules using BDI it did not happen as it does before mounting the initial ram disk. Seemed like a VECTOR LO/HIGH problem which their FAE did not or was not willing to explain. Too much pain for the effort required to resolve the problem with external folks... 5. On 8540, the BDI only worked with single stepping or running to a break point 5-10 instructions away. Not sure what was the problem as I had to relocate the entire U-boot code to run from a pre-init DDR RAM instead of a swizzled flash in 5-7 days with no PPC experience. Just schedule pressure becuase of lack of planning on other people's part. On top of that, the mgmt wanted me to limit hours. Not sure if to keep me less stressed or just be cheap!! 6. Based on the above experience with BDI, I recommended Metrowerks. On my project, one of the reference board was busted. We could not get it fixed. Each board was $2.5K each but they were useless. The software CD ROM was erased by someone (which had all the manuals). Somebody broke into my car and started smoking ciggerettes. So, what should I say. How far can one complain. I just told the psychologist that someone is giving me a hard time. Its definitely not any disorder.... Generally as engineer, we can differentiate between a bug a feature and a hack. When a hack (or a hacker) is trying to hinder your progress or cause grief or spoof a website so that you have wrong u-boot code, the individual is in trouble. Based on probability, its usually somone from the inside who changes code, crashes your CVS/clearcase or modifies code without a trace(perfect bug fix or hack by clearing logs or buffer underrun problem to hack). The cable off solution along with shutting down all the server apps was an easy solution as the kernel is not listening to sockets (since http server is gone from 2.4 kernel). And if the site is spoofed, its usually your area ISP who can help. (e.g. if you google for u-boot on source forge you only get u-boot 1.0.0 and if you access the site directly, you get access to 1.1.2 & 1.1.3). Thats the main reason for the resentment. Now, all one can do in these situations is complain. Now if the complain falls on deaf ears, what more can you do. Typical answer is that you are working too hard. But this is an easy forced attrition method. So, now if processors have a wireless link, forced attrition would be a common problem. And I am still objective. Wolf does not maintain the sourceforge site. He is just the moderator or main contributor. And we are not using VPN's globally to reduce spoof web site problem as many open source projects could have excess bugs in them... -- Atul From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from rwcrmhc11.comcast.net (rwcrmhc11.comcast.net [216.148.227.151]) by ozlabs.org (Postfix) with ESMTP id 73DB2689DD for ; Tue, 24 Jan 2006 01:16:14 +1100 (EST) Message-ID: <004701c62026$d1e48ba0$02c0650a@ATULSPC> From: "Atul Sabharwal" To: "Albert David" , References: <61124de70601220210i718fbc9cm85cdd282e739555e@mail.gmail.com> Subject: Re: u-boot debugging Date: Mon, 23 Jan 2006 06:10:52 -0800 MIME-Version: 1.0 Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original List-Id: Linux on Embedded PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , >>Herr DenkDenk provided an incredibly valuable service to the >>community, and deserves more respect than this.

Its easy to join a band wagon but be sure if you are on the right train. Not sinulting Wolf but I had to resort to this approach to explain the insult in his remark. Besides, as usual, lot of people have short memories. They dont scan the entire e-mail thread to see where the e-mail chain went wrong. Who instigated the whole insult cycle. And for the record, I did not insult wolf. He insulted me. I just humor & ridicule to convey my across.
