SYMPTOM

Downloading to Flash on the TMS470R1B1M or TMS470R1A288 device does not work properly if the Digital Watchdog timer (DWD) is enabled during the download.

CAUSE

The TMS470R1B1M (or TMS470R1A288) Flash algorithm was only refreshing the Analog Watchdog timer. The Digital Watchdog option, if enabled, was never refreshed by the downloader, causing the download to stop.

The Digital Watchdog option is only available on the TMS470R1B1M and TMS470R1A288 device.

RESOLUTION

The Flash algorithms for the TMS470R1B1M and TMS470R1A288 device have been updated to refresh both the Analog and Digital Watchdog timers.

To update your TMS470R1 Flash Algorithms and project:

  1. Download the TMS470R1 Flash algorithms and project from the Attached Files section of this article.
  2. Close all instances of uVision.
  3. Unzip the attached file into the following folder:

    ?installation_path?\ARM\Flash\

    where?installation_path?is the drive and path name you used when you installed the Keil tools. By default this is C:\Keil.
  4. Restart uVision.

Your TMS470R1 Flash algorithms are updated.

STATUS

Corrected in the next release of uVision
