8.1i EDK - UltraController 7.1i -> 8.1i Up-rev procedure

Description

What do I need to do to use the UltraController II reference design in 8.1i? When I take the 7.1i version of the UltraController II reference design and compile it under 8.1i, I get a bunch of errors starting with:

crt0.S:49: multiple definition of `_start'

Solution

The web site that contains the UltraController II reference design is being updated.

In the meantime;

- download the zip file and extract the contents into the <UltraController_dir>\sw\standalone\src\common directory.

- Add the compiler switch -nostartfiles in the Advanced tab in the compiler options.
