OSJTAG issues.

[KarlMarx]

Summary:

After updating the OSJTAG firmware, I am no longer able to connect to the serial-over-usb functionality in the pemicro terminal, etc.

Background:

I started by installing the tower toolkit off of the included cd, and followed along with the demo lab. At this point I was able to connect to the teminal, run the accelerometer demo, etc. I then installed codewarrior (10.1 se) and attempted to load/run one of the demos. At this point codewarrior brought up a notification to update the board firmware (which successfully brought me from rev. 27 to rev. 29.) The demo seemed to run fine, but I was never able to get terminal output from it; so I tried to connect from the pemicro terminal again, which also failed.

Details:

I checked the drivers, and noticed the usb serial port device was missing (but the debug port and jungo windriver were still there.)

I then followed the "troubleshooting serial driver" instructions here:

http://www.pemicro.com/osbdm/Installation_and_Operation_of_the_OSBDM.pdf

Specifically, I installed the pemicro firmware update tool, and updated to firmware rev. 30.

Once I reconnected the board, all three devices showed up in Windows device manager. Attempting to update the drivers returned that they were all the most recent versions.

I still could not connect to the USB serial terminal at this point. The terminal also occasionally reports read errors (I can't remember the exact wording, however.)

I've uninstalled all of the related tools and drivers from my system, and verified that I have the latest versions of all the installers. I will try reinstalling everything tomorrow, and see if it makes a difference; pending any advice I receive here.

TLDR;

Can anyone who has gotten the board to work with the rev. 30 firmware recommend an installation procedure/software combination that works? Has anyone else even had these problems?

P & E Micro has posted the latest firmware (v30.07) on their P&E Micro OSBDM Page. Just click on the Firmware Updates and Recovery link to download and install, and then run the Firmware Upgrade Utility to upgrade to version 30.07 (should be selected by default). This fixed my USB serial port issues with the K60 tower with Windows 7 64-bit.

Great - I did this - the firmware is now updated and the terminal program can't talk to it at all.

The best way to get an answer to your question is to file an on-line service request on ths problem. Click here to do that.

Re: Freescale TWR-K60N512

I followed along with the thread trying to get both PE terminal AND IAR debugger OSJTAG embedded link working.

Step 1: Download Toolkit DVD and IAR complimentary download. PE terminal worked and IAR debugger failed.

Step 2: Download latest PE OSBDM drivers. PE terminal failed and IAR debugger worked.

Step 3: Noticed Jungo USB serial not enumerated - loaded OSJTAG firmware V30 and latest toolkit. PE terminal worked and IAR debugger failed.

Where do I go from here? It seems that the IAR debugger interface for OSJTAG will only work with board firmware level

27 or 29.

Thank you, Zahar! That did solve the problem.

I am interested to know how you found that link though, in case of future need. Both the firmware update tool (where I found the rev. 30 firmware) and the standalone drivers package available for download at pemicro.com/osbdm (the address referenced in all of the pemicro literature I was able to find) contained the old drivers, and the tower toolkit file you linked is not available on that page. Admittedly, I did see the file (or some version of it) available on the freescale site, but never tried it, as I assumed the firmware update package containing the newest firmware would also have the drivers to support it.

Thanks again!

Hello Karl,

The OSBDM Virtual Serial Toolkit is avaiable on our OSBDM page (www.pemicro.com/osbdm).

If you look at the top right, you should see a picture with OSBDM Virtual Serial Toolkit written on it. This links to the same download given above.

Oh, I guess it is right there. I wonder how I missed it...

Thanks Zahar that worked for me..  Just installed latest version over current  using your link,

terminal connection is now open.

Good support here!
