program/erase MAX II with TDO disabled?

have you asked board's vendor?

Why did you so?!

from MAX II Device handbook:

--- Quote Start ---

Programming with External Hardware

MAX II devices can be programmed by downloading the information via in-circuit

testers, embedded processors, the Altera® ByteblasterMV™, MasterBlaster™,

ByteBlaster™ II, and USB-Blaster cables.

BP Microsystems, System General, and other programming hardware manufacturers

provide programming support for Altera devices. Check their websites for device

support information.

i know that in max10 there is separate jtagen pin to distinguish gpio and jtag on the smae pins,

but in max2 all jtag pins are dedicated according to handbook.

shoud you paraphrase question like "how to progam device without jtag tdo line in device"

if it possible put you gpio in tristate.

or write your own driver that provide expected values from tdo line to software. so you should return to the first sentence.
