Newbee,
Okay, for TMS320F2808 in SYSBIOS 6.35.4.50 the *.cfg files does not contain any MEM segments or sections. If you are porting over your .tcf file to .cfg, remove any references to MEM segments or sections.
All MEM segments and sections is left to the linker command file.
The Platform to use is "ti.platforms.tms320x28:TMS320F2808".
If you create an SYSBIOS example for TMS320F2808 using the TI Resource Explorer, you will see what I'm talking about. We automatically insert a .cmd file named TMS320F2808.cmd. You will also find these .cmd files under your xdctools installation. Something like the following:
C:\ti\CCSv5.5.0.77\xdctools_3_25_03_72\packages\ti\platforms\tms320x28\include
