Part Number: TMS570LS1227
Other Parts Discussed in Thread: TMDSEMU110-U, LAUNCHXL2-TMS57012, UNIFLASH

Hi,

I've just received a debugger:

I wanted to check its work using connection to test board that I've.

 LAUNCHXL2-TMS57012 

I'm using UNIFLash 3.X. on Windows XP.

I've got this error:

==============================================

Error connecting to the target:
(Error -2131 @ 0x0)
Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 6.0.83.1)

==============================================

If I connect, using in-build proger, connection successfull.

What am I doing wrong or how to check my device is ok.

Thanks

Andrey

    Hello Andrey,
    If I understand correctly, you manually soldered on a 20-pin JTAG connector to J1 of your LAUNCHXL2-TMS57012 and then connected an external XDS110 debug probe to it an is unable to connect to the target. But if you use the on-board XDS110 via USB cable, it connects fine.

    Is that correct?

    Thanks

    Hi,

    yes you're right.

    I've done that. But I've already solved this problem. I was forced to install Uniflash 4.x to Windows 7 on another PC to make it work.

    Unfortunatelly standalone XDS110 DOES NOT WORK with Uniflash 3.x that can be runned on Windows XP.

    But I have two more questions:

    1) Is there some other more friendly IDE/API to read/write binary flash files using XDS110 than Uniflash (who the hell wrote this prog?!!)

    2) Why debug probe shows serial number 0000000 when on the box there is a valid serial number?

    Thanks

    One thing to check is to make sure you have the latest emulation drivers installed for UniFlash 3.x. That is important for the standalone XDS110. I tried UniFlash 3.4.1 (with updated emulation drivers) with my standalone XDS110 debug probe and it works for me (though I didn't try on XP)

    in any case, it is good that you upgraded to UniFlash v4. That is recommended anyway.

    There was some old standalone program called NowFlash, but I believe that has been discontinued in favor of UniFlash

    It could be that the serial number was reset. You can always set the serial number yourself via:
