Hello,
Thank you for answering my question, Please let me clarify,
It is easy to create the POF with JTAG -enable in Quartus tool (using convert file) of the document above.
1) Page 55. after power up and configuration of the JTAG-ENable. POF, MAX 10 is in JTAG secure mode.
page 56 To disable if "trigger the start_unlock port of the user logic) and issue UNLOCK JTAG INSTRUCTION.
The device exits from JTAG secure mode.
Do I need to pull nConfig pin LOW ? (page 28 describes configuration sequence) . or do anything with nStatus, CONF_DONE?
2)
After I enabled the JTAG secure mode, power off and on. I can't erase, configure or program the MAX 10 any more.
I pull on the UNLOCK I/O pin HIGH, it does not work. I send in UNLOCK instruction via
test_unlock using
quartus_jli -c 2 unlock_208.jam -a unlock
