Other Parts Discussed in Thread: 4430, CCSTUDIO

Hi there,

I'm seeing following error when I test JATG interface. Could you please let me know what would have been wrong?

Please let me know if you need any info.

CCS version: ccv v5

JATG:  BH-USB-560BP

Board: panda 4430

-----[Print the reset-command software log-file]-----------------------------

This utility has selected a 560-class product.
This utility will load the program 'bh560ubp.out'.
E_RPCENV_IO_ERROR(-6) No connection: Client has disconnected
Failed to open i/o connection (bh560ubp:0)

An error occurred while soft opening the controller.

-----[An error has occurred and this utility has aborted]--------------------

This error is generated by TI's USCIF driver or utilities.

The value is '-250' (0xffffff06).
The title is 'SC_ERR_ECOM_EMUNAME'.

The explanation is:
An attempt to access the named emulator via USCIF ECOM has failed.

Thanks & Regards,
Venkat

    Hello Venkat,

    The error you are seeing is usually caused when the host PC cannot communicate to the emulator. Check that your emulator is properly physically connected to the PC and that your device is recognized by your PC (properly enumerated and drivers loaded). Try rebooting your PC also.

    Thanks

    Hello Ki,

    Thanks for your prompt reply.

    I have verified connections and driver initialization twice before posting this query. Please let me explain my setup to keep you in sync.

    1) Installed CCS V5 licence version

    2) Followed the instructions in the following link

    Hello Ki,

    JTAG interface started working after rebooting the system. I guess it was problem driver initialization.

    I'm trying to load uboot binary ( file <uboot>  not uboot.bin) on omap4430 panda board. When I load the problem I don't see any error window message but in console I see following error.

    CortexA9_0: GEL Output: --->>> Keeper force done <<<---
    CortexA9_0: GEL Output: --->>> omap4430_startup_sequence DONE !!!!!  <<<---
    CortexA9_0: AutoRun: Target not run as the symbol "main" is not defined

    I would like to know whether it is possible to debug MLO (x-loader) and Uboot code on omap4430/omap4460 panda boards?

    Please let me know the procedure to debug MLO and Uboot source code.

    Thanks & Regards,

    Venkat

    Hello Ki,

    I have followed the steps given in the video (http://software-dl.ti.com/sdo/sdo_apps_public_sw/CCSv5/Demos/u-boot_debug_autonomous/u-boot_debug_autonomous.html) but it didn't help me completely.

    X-loader and U-boot which get executed successfully when I boot from SD card are not executed from CCS V5. I don't see serial out and error messages from x-loader and U-boot execution through CCS V5.

    Any help on this will be much appreciated.

    Thanks & Regards,
    Venkat

    I came into the same problem before, although not the same board.

    Finally, I solved it by run "sudo /opt/ti/ccsv5/eclipse/ccstudio" in terminal. Maybe it's a problem with permission.
