TUSB9261: BSDL file and in-system programming code

Andrew Dyer
Intellectual 650 points
Part Number: TUSB9261


We are looking at methods to program the SPI flash attached to TUSB9261 and had some questions:

1) is the BSDL file available if we choose JTAG?

2) can I get a copy of the Linux in-system programming code that is referenced in other threads?

3) if the part is held in reset (GRST_N low) does the part tri-state SPI_CS0/, SPI_DATA_OUT, SPI_SCLK pins so we could add a header and use a spi programmer?

    Hi Andrew,


    1)

    tusb9261_bsdl.zip

    2)

    6327.tusb926x-flashburner-0.1.2.zip

    3) I'm not 100% sure on this one as I don't have access to the design specific params for this module but this what I could dig up:

    The following apply if a device is under reset:

    • Pull control. The reset pull control on the pins is enabled or disabled depending on a device-specific option.

    • Input buffer. If the reset pull control is enabled, then the input buffer is also enabled. If the reset pull control

    is disabled then the input buffer is also disabled.

    • Output buffer. The output buffer is disabled.
