Installation

Installation is integrated with CCS. See CCS install instructions or Quick Start included with your eZdsp. To install from the Spectrum Digital ftp site download the latest drivers, unzip drivers to temp directory and run the self-extracting installation.

Where To Find Things

Under the installation directory, <INSTALL_DIR> you can find the following:

• docs\pdf : eZdsp user guides and schematics.
• docs\releasenotes: This file and other release notes.
• drivers: Emulation drivers, *.dvr files.
• drivers\import: CCS setup configuration files.
• specdig\SDConfig: Spectrum Digital emulator configuration utility.
• specdig\SDFlash: Spectrum Digital FLASH programming utility.

SDFlash

The SDFlash utility is included for programming support. Device specific algorithm and example files are not included in the base install. You can find these in one of three places for the specific device you wish to program.

1. On the installation CD in zip format.
2. On the Spectrum Digital web/ftp site.
3. On the Texas Instruments web/ftp site.

Basic instructions on where to unzip the flash files are documented in the “project_readme.txt” file located in the “specdig\sdflash\myprojects” directory. The FLASH algorithms are device revision dependent so make sure you match the algorithms to the device revision. Following is summary of current F28xx algorithms.

F2810/12 Silicon Rev	REVID (0x883)	SDFlash Algo Version
blank	0x0000	tif28x_v1.zip
A	0x0001	tif28x_v1.zip
C	0x0003	tif28x_v2.zip

SDConfig

In version 2.2x of CCS you have the ability to run external emulator diagnostics during “Reset Emulator” or during CC startup in the event of an error. All of the Spectrum Digital CCS configuration files will point to SDConfig utility. When staring CCS if a serious error occurs you will get a dialog, which has an additional button for diagnostics. If you select this button then the SDConfig utility will be launched. At this point you can check your port settings and test your emulator connection. Once your emulator connection is tested you exit SDConfig and retry CCS.

Once CCS is launched you also have the same capability via the “Reset Emulator” command under the Debug menu.

Known Problems

• If you loose power on your target or emulator CCS will pop up the “Reset Emulator” dialog box. If you choose to reset the emulator then CCS will execute outstanding debug commands that have been queued up as well as clear breakpoints and go other target house keeping. However, as power was lost these commands cannot complete and will return an error code. These will be reported as errors in the CCS output window. In some cases other dialog boxes may pop up. If this occurs you can select the cancel button until you get to the “Reconnect Emulator” dialog box. At this point CCS has flushed its command queue and released the emulator connection. You can reconnect or run the diagnostic utility. This is a CCS 2.2 shortcoming, which TI is aware of.

• Real-time startup on F24xx can be little tricky. The following gel sequence will make things a little easier.

Hotmenu SetupRealTime()

{

/* Start real-time app from reset */

GEL_Reset();

/* Init real-time monitor */

GEL_Go( MON_GO );

/* Enable real-time mode */

GEL_EnableRealtime();

}
