New ContributorCyclone10 LP Custom PCB IO Pins Always HIGH issue
I'm just writing 1's and 0's to my onboard 8 LEDs. Which are all HIGH all the time no matter what I write to them. And here is my simple demo project

The unused pins are "input tri-stated" in the device configurations.
Doing power recycle while holding the nConfig button LOW results in all FPGA pins are HIGH even before config starts. When i release the nConfig button, the config DONE LED lights ON, and all the FPGA IO pins are still HIGH same as before.
Super ContributorWhat design are you using to test this? Some code might be helpful.
What do you have the unused pins set to in the Device & Pin options?
Are you saying that every single GPIO pin is stuck high after programming?
