Hi Nhu-ha,
I have just tested on my side, seems like no problem in locking and unlocking. Just would like to check, how do you unlock the MAX10? From the above statement, seems like u were running the command to unlock. If it so, can you try to provide a pulse only to UNLOCK pin? With the unlock pulse, the JTAG will be changed from internal JTAG mode to external JTAG mode and thus you can do programming and erasing using JTAG. No command is needed to unlock.
Also, speaking about the design, once you program the POF file obtained from the reference design available at link below:
https://fpgacloud.intel.com/devstore/platform/15.0.0/Standard/max10-jtag-secure-unlock/
The device will change into JTAG secure mode once the device is powered on.
Thank You.
