Hi there,

For max 10, if you don't wanna max10 load the image from cfm, you can pull low the nconfig after power up(ep: you can connect the nconfig to gnd). After you enter the user mode, you can use the programmer to detect the cfm and erase it.

The 'jtagen' may be the reason why you cannot detect jtag line, if you sure it is the reason and wanna solve it, you can pull down the "jtagen" pin. Of course, the way you pull down the nconfig can also solve this problem.

Best regards,
