What is the value of your current limiting resistor? Did you put a scope or a meter to measure the output pin?

Thank you for your replying,

I couldn't really measure the current, now. Because I work in a starting project. But it was an experimented engineer, who develop that board. So I think he should think about that.

I thought it may be have problem of compatibility of USB blaster II, which is not compatible with Altera max10 or the frequency of Jtag, 6MHz instead of 24MHz, but I don't know how to change that frequency
