1 year agoYou can...add a pull up. It's required for that signal since it's open drain: https://www.intel.com/content/www/us/en/docs/programmable/683865/current/configuration-pins.html

So how come most boards work well without a pull up? Is it random?

"Most boards" is not all boards. If this is a board you are putting into production, you would not be able to go without the pull-up.
Why is it working on these boards? Not sure. The die on the ones that are working may be able to barely get to the high voltage level needed to register correctly. Luck of the draw (and luck of the fabrication).
