Secure Jtag on Max 10 ---

Hi Nhu-Ha Yup,

There is no switch to change your device in JTAG Secure Mode. You will need to enable the mode in Quartus, compile and generate a POF bitstream.

Enabling JTAG Secure Mode will cause your device to be able to use the instruction as shown at table below:

Thank You.

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

Hi Nhu,

Please find my response below:

1) You dont need to pull the nCONFIG LOW, the configuration pin will pull itself. You will just need to issue UNLOCK JTAG INSTRUCTION.

2) May i know if it works after you issue UNLOCK JTAG INSTRUCTION?

Thank You.

Hi Nhu,

This is weird. By right it should be able to program after you UNLOCK it. May i know, have you observed if "indicator" port is going HIGH? You may also refer to the steps to UNLOCK as shown at link below:

Thank You.

Hi Nhu,

I will continue to support you in another thread.

Thank You.
