    Hi Chris,

    Sorry about the bad news. Unfortunately after consulting the engineering team, we are unable to provide the definition on how to use the built in function and the source code as it is private and confidential. However, do feel free to use the macros which is the IORD or IOWR that calls the built in function.


    I will set your case to close-pending if I do not hear from you the next few days. Thank you.


    Regards,

    Kelly

Hi,

After you download the link and unzip the files, the directory to find _builtin_ldwio is : Downloads\acds-16.0.tar\acds-16.0\acds-16.0\gcc-5.2\gcc\testsuite\gcc.target\nios2 and locate to nios2-builtin-io.c .You should be able to see the source code in the file.


Thank you.

Regards,

Kelly
