Howdy Min,
IT is currently addressing an issue with our external ftp website, but when the problem gets resolved the software can be downloaded at:
ftp://ftp.ti.com/pub/data_acquisition/AMC/AMC7812EVM/amc7812evm-0.8.0.0.exe
The software is too large to attach to an email, but if the problem doesn't get resolved soon, we may develop a short term solution.
Best Regards,
Matt
