Codewarrior USBTAP problem

dcogley — Tue, 06 Jun 2006 01:02:44 GMT

Hello,

I am evaluating the 8349 Freescale processor using the MPC8349E-MDS-PB evaluation board. This evaluation came with the Codewarrior USBTAP with JTAG interface for loading and debugging applications for this microcontroller. I have installed the evaluation Codewarrior Development Studio for PowerPC ISA, Linux Application/Platform Edition v2.6. I have also installed the required ROHS USBTAP update.

On to the problem.. I have created the simple test application in the Codewarrior IDE and configured the Remote Debugging to use the USBTAP. When I choose Debug->Connect I can see the board reset and the connection status proceeds all the way to "Completing connect phase..." then gives me an error:

"JTAG Clock Speed Change Error"
Please check your JTAG clock speed.

Then the error:

"CCSProtocolPlugin: CCS: Network timeout
[Network timeout]

I have tried every "Interface Clock Frequency" under the USBTAP settings and I always get the same error. I have read through the USB TAP users guide and located the section "Setting the Debug Port Clock Frequency" which refers me to the CodeWarrior documentation under which I can not find any information for the USB TAP.

Thanks,
Dave Cogley

Help I have the exact smae problem

I have had many problems with this TAP... I have gone through four TAP's each with similar problems.

The TAP seems to work right? But let me guess when you plug it into the USB port the LED's flash then Tx/Rx blinks RED? If you see this it apparently means that the USB controller on the TAP cannot communicate with your PC. I'll bet that the TAP probably worked fine for a while?

Anyway, the problem maybe ESD. If the target H/W is charged as you connect your H/W the ESD appears to damage the USB controller on the TAP. Same thing can happen if the TAP is connected to the PC...

My local rep and distributor has helped me greatly with supplying me with replacement TAP's and other TAP's as well. Ask if Freescale has a parallel port version of the TAP for that processor. I was able to get "DSPCOMMPARALLEL" from AVNET, seems to work just fine, all you need is a parallel port I think this TAP is configurable for any processor...

Good Luck

Unfortunatly this USBTAP has never worked. The TX/RX lights are flashing green under my Linux (Fedora 4) disto. I can't get the USBTAP to work at all under XP. No drivers?? It starts to communicate to the board as I can see it reset and makes it all the way to "Completing Connection Phase" before failing. I have tried using the Ethernet interface for debugging but I can not login into telnet. I tried logging in as root and it is an unrecognized username.

I have the same problem about USBTAP. I have wrote the problem to freescale but nobody replied me yet.

here is the problem that I have encountered:

I want to program and debug flash but I have seen an error always while erasing flash.I am using USBTAP to flash my evaluation board EVAL8540. but it does not
work. I am using correct initialization file(8540EVAL_init.cfg) and
correct settings.

Target memory buffer address: 20000
Target memory buffer size: 200000
Flash memory base address: FF800000
Device : IN28F64OJ3 (4Mx16x1)
also my USBTAP interface clock frequency is 22.27 MHz.

when I want to erase it shows a message like this:

Flash Programmer: Can not initialize the target: "8540" Please make sure
"C:\Program Files\Metrowerks\CodeWarrior PowerPC Comm
V8.5\PowerPC_EABI_Support\Initialization_Files\PQ3\8540EVAL_init.cfg" is a
valid configuration file. Additional error information: Interface
function IMWProtocol::GetPreference is unimplemented

what can I do?is there anyone could help me?

Hello

I am not an expert in EPPC85xx, but here is what I know from my experience with USBTap.

Which CodeWarrior product did you install? To retrieve that information:
- Start the IDE
- Select "Help" -> "About Freescale CodeWarrior"
- Click on "Installed Product"
- All the installed product are listed in the upper part of the window.

Which is the revision number on your USBTAP? (You can find that information on the back of your USBTAP.

If you have a REV X2 you need to install the "ROHS USBTAP Windows Update v1.0".
Browse to the bottom of the page and click on USBTAP-UPDATES .

Make sure you are using the appropriate version of CodeWarrior (look at the text of top of the download page).

I hope this helps.

thanks Crasycat,

I have 3 version of codewarrior (all of them are evaluation version) I have Codewarrior for EPPC Linux 2.6 and this version has not any flash programmer version.another version is Codewarrior powerpc comm.V8.6. this version is opened but when I want to use flsah programmer, I can open it but I can not verify or program. it gives me an error like this("unable to use the plugin EPPC Flash Programming It is licensed and a valid license key was not found") what is the problem?? I can not understand. I have a license for 15 days(dafault one) also I have encountered the same error in Linux redhat 9.0?

finally I tried to Codewarrior PowerPC Comm. v8.5 and I can not program it gives me a error message like "make sure ...\ ...\... initialization file is a valid configuration file. Additional error information: interface function IMW Protocol::Get preference is unimplemented."

I can not solve the problem.I have patched USBUpdate v1.0and USBTAP V1.6 firmware upgrade. but nothing has changed??

CrasyCat — Tue, 13 Jun 2006 21:04:14 GMT

Hello

Apparently you have a licensing issue with your CW EPPC V8.6. I would need to look at the license file to investigate further.

Where did you install the license file?

New revision of USBtap will not work with V8.5 You need to install the ROHS Patch on top of V8.6.

On Linux can I also get a look at the license file you are using?

Hi CrasyCat,

I have solved the problem but now I have an another problem I hapo yu have any idea.

I want to debug kernel using USBTAP and Codewarrior (hosted on Windows Machine)

do you know how can I debug?

Re: Codewarrior USBTAP problem

CrasyCat — Wed, 14 Jun 2006 16:59:55 GMT

Hello

May I ask you what was the problem? I am just curious.

When you are speaking about kernel debugging, are you speaking about Embedded Linux kernel debugging?

Embedded Linux Kernel debugging is possible only with CodeWarrior Development Studio for PowerPC, Linux Platform Edition.

You need a Linux hosted machine to do kernel debugging.

If you only have Windows hosted machine, only solution I can think about (I have used it a while ago) is to use VMWare and create a emulated Linux machine on your Windows host.

I hope this helps.

We are also having the problem decribed in the original message of this thread. We are using linux version 2.5 and have updated the Tap through ccs. The debugger gives the error:

CCSProtocol Plugin : CCS:CoreNotSupported connection refused

and the Flash Programmer gives the error

JTAG clock speed error and/or
Flash programer cannot initialize target 8272 blah make sure config file is correct.
We are trying to program an mpc8272ADS board and are following all instructions given to us.

What is the correct clock speed for the JTAG? and if this is not the problemn then what is?

We are using Linux RedHat 9.

If anyone has an answer to this please email it to me at

Hello

If you are using a CWH-UTP-PPCC-HE parts, you need to download and install the USBTap patch.

Note that he patch can be installed on top of CodeWarrior™ Development Studio PowerPC® ISA, Linux® Platform and Application Editions v2.6 only.

So you need to upgrade to V2.6.

CrasyCat

Re: Codewarrior USBTAP problem

AAC_newbs — Thu, 15 Jun 2006 20:57:38 GMT

OK we have installed v2.6 and the update, but the same problem still exists. The debugger and the Flash programming tool keep telling us that there is a problem with the JTAG clock speed. In v2.5 there is an option to change this value, but in 2.6 there is not.

This is very frustrating and is halting progress of our project, we have been fighting this for about 5 months, and have even sent a tap back in thinking it was damaged.

Is there some way for us to use the WireTap JTAG programmer which we purchased with the board, there is no option in the Remote Connections for the use of this Tap, and it maybe that we need to have a new plugin for CW.

Thanks for your help

Hello

I would suggest you to submit a service request through our web interface for that.

Sorry I cannot help more on that one.

MEP — Fri, 23 Jun 2006 11:07:21 GMT

I'm not sure if this would fix the JTAG clock error, but I believe I have resolved a connection issue that I've been fighting with over the last couple of months on the USB TAP that may be related.

I have been trying to set up two USB TAPS as flash programmers for one of our products that uses an 8270 processor. I kept getting errors when the flash programmer was loading the flash driver to the processor memory. Hardware diagnostics also failed all tests while attempting to access the processor memory. Sometimes the programming/erase/blank check would start but then fail shortly after with an error like "target in unexpected running mode" or one of a couple other messages. These problems were exhibited by both USB TAPS and also after a re-install of the CW software.

To complicate things more, some of the boards that were working with the flash programmer one day would stop working the next especially when I moved the setup down to the manufacturing floor. Our customer also has purchased a USB TAP so that they can reprogram the cards if needed. They have not reported any problems with it yet.

After numerous e-mails back and forth with Freescale support and a visit from the local FAE (Whose USB TAP and laptop running CW also had the same problems with our boards.) the issue was still not resolved.

I stumbled upon what may be the answer to this simply by chance, noise. I had noticed that when a twist was put into the ribbon cable of the USB TAP, my connection problems stopped. Since then I have run about 30 boards through flash programming with tin foil wrapped around the ribbon cable on both USB TAPS and had no errors come up. As soon as I remove the foil from the cables and try to start a flash operation the errors would come back.

If there is a problem with noise sensitivity on the USB TAP JTAG cable, could it be possible that it was also interfering with the JTAG clock signals?

Regards,
Matt

The solution to our problem was to use a different machine as the host.

It seems that the USB devices on the HP compaq computer we were using were causing the problem. We have changed to an ACER laptop and have not had that problem any more.

I've the same problem. When attempting your suggestion, under help I get "about Metrowerks CodeWarrior" and no option to click on "Installed Product". What next, Carzy?

CrasyCat — Tue, 15 Aug 2006 15:23:43 GMT

Hello

I would also suggest you to open a service request for that.

Note that if you do not have a "Installed Products"+ button in your About box, you are probably running a pretty old version of CodeWarrior.

This will probably not support USBTap HTI.
