jtag secure mode (arria 10)

Hi,

Is there an order in enabling security bits? Would enabling JTAG secure

mode first lock me out from enabling any of the other security bits?

• Yes, the order can matter, depending on your device.Generally:
  • If you enable JTAG secure mode (or any security mode that restricts debug/programming access) before setting other security bits or configuring options, you may lock yourself out of making further changes via JTAG or other debug interfaces.
  • Best Practice: Set all desired configuration and security bits before enabling JTAG secure mode or any permanent lock.

And is programming/verifying included in the list of jtag commands not

permitted in secure mode?

Yes.

Thanks.
