Frank,
Using the 2.23.2.03 NDK and building it using DEBUG_LINK_STATUS and USE_CPSW_DRIVER predefined symbols, the build completes, but the .map file does not show the cpsw_ethdriver_register_link_change() function. Going back to our current build and using the 2.23.2.03 NDK shows that the linker can not resolve cpsw_ethdriver_register_link_change().
Thanks,
John C.
