Set an 8-bit bidirectional IO port as output mode in NIOS2 code, but only 4 bits (bit 0, 1 ,4 ,5)can output correctly, and the other 4 bits hold out state 0.
Can you please explain more? what is your issue?
please check the top level connection first. you can share with us the top level connection and the assigned pins for these LEDs.
Thanks you .I removed signaltap from the project, it works correctly.
