Doc ID 16955 Rev 1

This tool allows you to select memories and request the configuration values. A progress

page is displayed while the script runs, and the file can be downloaded when the script

completes.

Once the configuration values for SPEAr600 are obtained from the Web tool for the selected

DDR part, these values should be updated in the Xloader code.

In the Xloader code, there are separate DDR configuration files for SPEAr600 in a folder

named “DDR”. You need to create another similar DDR configuration file for the memory

part in use with the values received from the Web tool. Moreover, it is necessary to make

sure that the PLL of the SPEAr system used to clock DDR is programmed for the selected

DDR frequency. Refer to the miscellaneous block chapter of the SPEAr600 user manual for

details.
