Hi Biyong,

     Your documents are always helpful, thank you for sharing! I checked the latest "Generate Blob Under Linux" document, but it seems the link doesn't work. Can you please check the link again? Thank you!

Best Regards,

Frank

[BiyongSUN]

I don't know about what happened.

I use another way to  populate the document.

You can check it can link you to the right place.

And Please let me know it works or not.
