Beaglebone kernel debugging with CCS v5.1

Hi,

I'm using a Beagle bone REV4 with all software installed on an VMWare.Ubuntu 11.04. I can compile my kernel and use it with a tftp/nfs boot. I can use the CCSV5 to debug in RUN MODE (user space application).

BUT I fail trying to begin with Kernel debuging with CCS. I've tried the sitara support package documentation or such tutorial below but no way.

http://beagleboard.org/static/beaglebone/latest/Docs/ccs-jtag-simple.htm

THe main problem i think ? is that I never can have a connection such as XDS100V2 USB Emulator ? I think i need this connection ... but not sure.

The BBone should embed necessary hardware  but noway, I never have any other "connections" than "Data snapshot viewer". and indeed the directory "ccs_base/common/targetdb/connections" does nt contain anything else than "DataSnapshotViewer.xml".

Please help ?

    HI all,

    My problem is not solved but i got a workaround.

    In fact, none of my available Windows Desktops (Vista or 7 32 bits) would work with the BeagleBone except one : An old XP one !!!

    Then i could modify the VID/PID get back to my Linux and ... ouf ... connect to the JTAG/USB emulator ! cool !

    I've to go further trying the "STOP MODE" debugging on my Kernel.

    Thanks for all your suggestions.

    Hi,

    Thanks for reporting back the solution... It is indeed really strange you couldn't access the board from a Win7/Vista PC.

    Quick question: what is the brand/model of the PCs you used? This information could help other developers that experience similar issues...

    Thanks,

    Rafael

    HI again,

    Ouups, i forgot to mention the computer on which it has worked correctly: Laptop SAmsung X22 / XP pro 2002 SP3 / Intel Core 2 duo T7500

    Anyway, I'm still struggling to make run my debug "stop mode" for Jtag/USB Kernel debugging.

    Now i can create a "Target configuration" file that can correctly connect and "test connection" seems OK (see below).

    But when i launch my "Debug configuration" (see joined screenshots) my CCS 5.1.1.00033 immediately return with the following error :



    Hips .... if anyone has got an idea ?



    Here are the screen-shots of my debug configuration:

    Back to my problem ...

    Even if the board can now be seen on XP PC with 0403/6010 VID/PID it is still not visible from any of my Vista or 7 !!!

    I'm desesperate with that can't even us the board on any of my regular PC. Is ther any requirement about vista or XP to recognize the FT232H device ????

    Please help !

  • In reply to peg:

    So it seems that it works with 64 bits Windows not on 32 bits ones .... is ther any palliative please ?

  • In reply to peg:

    Hi,

    Whenever you connect your BeagleBone to the Windows 7 / 32 bits, does it show the "new hardware found" window? If so, make sure you install the standard FTDI drivers on this OS - the boards with the updated VID/PID do not use the TI XDS100 drivers that are installed with CCSv5.

    A link for download is shown at this FAQ.

    Hope this helps,

    Rafael

    Hi,

    Yes it does but the recognized VID/PID is weird !! See screenshot.

    Not that connected to my XP the same board shows correct VID/PID and use correct FTDI drivers.

    Yes i've already used the FAQ to pass my VID/PID form 403/A6D0 to 403/6010. Done on XP !

    But any of the programmed VID/PID the recognized VID/PID on 32 bits Windows vista and 7 is the one shown on the screenshot.

    Hi all,

    The problem is solved, and is so simple !

    In fact it seems that beaglebone has also a USB HUB on board [USB\VID_0424&PID_2412&REV_0;;2USB\VID_0424&PID_2412]

    and this one was definitly not correctly installed on driver side of my Windows 32 bit PCs.

    Here is a driver that has worked for my windows vista premium 32 bits. And thereafter the the two FT2232H dirvers are correctly installed.

    Thanks all

    Thanks for reporting this; I imagine the fact you were using a virtual machine can influence this yet unreported behaviour (at least on the BeagleBone mailing lists).

    Thank you,
