Why do I get the following error "Undefined reference to <function name>" when performing the nios-build in the Nios embedded processor 1.1 on code developed with the Nios embedded processor 1.0? - Why do I get the following error "Undefined reference to <function name>" when performing the nios-build in the Nios embedded processor 1.1 on code developed with the Nios embedded processor 1.0? Description The naming convention has changed for many predefined Nios embedded processor routines in the Nios embedded processor 1.1. A header file, nios_10_to_11.h , and an assembly file, nios_10_to_11.s , are provided in the directory of your project's software development kit (SDK). Including these files in your code by adding the following lines to your code will resolve the naming issues: "nios_10_to_11.h " "nios_10_to_11.s" Custom Fields values: ['novalue'] Troubleshooting novalue False ['novalue'] ['novalue'] novalue novalue ['Excalibur™', 'Programmable Logic Devices'] ['novalue'] ['novalue'] ['novalue']
