[quote user="Jonathan Ruby"].emsg "Project build options do not match Global configuration settings. Compiler options specify Big Endian, configuration set for Little Endian."[/quote]
The message is saying that the project build options specify --big_endian as you can see in the options passed to cl6x, however the BIOS conifguration is set for Little endian. Please check the BIOS config file to verify this.
Was this a newly created project in CCSv5 or one that was imported from a previous version of CCS?
If you go into Project Properties and ensure that the correct device you are working with is selected, it should automatically pick the correct endianness for the BIOS config file. If this does not do it you may have to manually adjust the endianness in the BIOS config file, which you can do by opening the .tcf and going to System->Global Settings->Properties.
Hope this helps.
