Yes, I would work from the version in the repository. See the wiki page for details about the symbols in those files. http://opencores.org/or1k/Newlib#Board_support_details A TODO on that wiki entry is to add an example of the commands to run the assembler on that code and then archive the object code into libboard.a Cheers Julius _______________________________________________ OpenRISC mailing list [email protected] http://lists.openrisc.net/listinfo/openrisc
