Regular ContributorHello,
It seems like the pin locations you set do not support weak pull-up resistor. Please refer the guideline from this handbook and change your pin location assignment: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyclone-10/c10lp-51003.pdf
Thank you.
