Hi,


Please check if the design that you used has the unlock function.

The reason is that based on the testing, I understand that the design in the flash does have this function where after you power cycle and the Max 10 device is loaded with JTAG Secure design and JTAG unlock function then you were able to unlock the device successfully.

If you are using the incorrect design then you will face issue on unlocking the JTAG chain and will cause JTAG programming to fail.


Thanks.
