Using WinROM to Configure the EEPROM

www.ti.com

A new dialog box appears that allows the user to select which .dat file to use to program the EEPROM
(see

Figure 1-13

). Select from one of the three operating modes supplied with the EVM.

Figure 1-13. Selecting a .dat File

After the Open button has been pressed, a new dialog box opens asking if the user is ready for WinROM
to begin flashing the EEPROM. After selecting yes, WinROM starts flashing the EEPROM with the
contents from the file (see

Figure 1-13

). The .dat files are text documents that can be modified by the

user.
