Hi,
I'm running CCS rev 5.1.0.09000
Go to Tools, RTSC Tools, Platform, New.
In the External Memory box for the new platform, enter a name then try to enter a base address. Type in 0X800000. You will see the first '0' and then it looks like something has gone wrong. If you happen to have Caps Lock enabled after entering an upper case name, and you enter 0x800000 you will see the same thing. Only if you enter a lower-case 'x' does the data when you entered appear on the screen. It's confusing if you don't realize that upper-case X is not accepted.
Annie.
