UCD9248 - JTAG Interface - Need BSDL File

Gray Brightman

Other Parts Discussed in Thread: UCD9248

My customer's board uses a UCD9248 and he wants me to program it using an SVF file via the JTAG interface.

I am using a third-party Boundary Scan (JTAG) software tool and this needs a BSDL file for the device. I cannot find a BSDL file on the TI website. Does the file exist?

    Gray,
    The UCD92xx devices support JTAG to gain access to the ARM processor memory.  The JTAG interface does not support boundary scan.  If you download the Fusion Digital Designer software, there is also a set of documentation (found under Start/Texas Instruments Fusion Digital Designer/Documentation and Help Center) that describes the process of writing an image of the configuration memory to the device over the JTAG interface.  Today we only support the SVF file technique.  TI is working with several ICT tester companies and is continually adding support for ICT testers, so you may want to download the latest GUI to get the latest documentation.

    I understand that the JTAG interface does not support what you refer to as 'Boundary Scan' but in order to communicate with the interface, the host system needs knowledge of the internal registers, opcodes, register lengths etc. Other manufacturers of JTAG devices supply BSDL files containing that information.

    Even if the device does not have a boundary register, it can still have a BSDL file.

    Gray,

    Actually there is a BSDL file for the device.  It is referred to in the "Configuration Programming of UCD Devices" document in the Documentation and Help Center that is included with Fusion Digital Designer GUI.  You should find it in the directory C:\Program Files\Texas Instruments Fusion Digital Power Designer\misc\UCD30xx.bsdl.  Sorry for the misdirection.

    Hi Mark - thanks for the reply. I have downloaded the application and got the BSDL file but it does not look right to me. The pin numbers do not correlate with those in the datasheet. for the LQFP80 e.g. TCK in the datasheet is pin 44 but in the BSDL it is specified as pin P2.

    Mark,

     

    In your response to Gray regarding the location of the UCD9248 BSDL file you stated it was included in the Fusion Digital Designer GUI.. Can you tell me where I may find that?

    Thanks,

    Mitch

    Mitch,

    It would be located within the directory where the Fusion Digital Power Designer was installed under the sub-directory misc.

    If the default settings are used during installation then the file is located at the following path:

    C:\Program Files\Texas Instruments Fusion Digital Power Designer\misc\ucd30xx.bsdl

    Can someone answer this query regarding the pin numbers in the BSDL file.

    Gray,
    I believe that the pin map in the BSDL file is actually the die pad numbers.  Here is the DSDL pin map designators as they relate to the pins on the 80-pin, 64-pin, 48-pin and 40-pin package version of the UCD92xx controller.
