28027 Flash programming calibration

Other Parts Discussed in Thread: TMS320F2811, TMS320F28026, CONTROLSUITE

Question asked:

We are working on supporting TMS320F28026 programming through external programmer. We already support TMS320F2811. We already:

  1. start internal oscillator, (using examples function)
  2. initialize PLL with mult=6 and div=1, (using examples function)
  3. initialize peripheral clock (using examples function)
  4. setting new baudrate

The DSP answer is not correctly calibrated. Can you please provide us some informations on clock differences between TMS320F28026 and TMS320F2811? Does the Flash API library has to be used at the maximum clock speed?

    If I understand, the toggle test is not showing a correct configuration?  The first thing I would recommend checking is the cpu scale factor.  If the application is using the API in the boot ROM, then the scale factor must be at a particular location and that location is EALLOW protected.

    Hi Lori,

    Is there a document that I can use to follow up on the flash program ? I cant seem to find the flash API example for the 28027F.

    I would like to read and write from the flash. Can you point me to a controlSUITE example if there is one ?

    Regards,
