You can't logic your way out of being burnt out. Unless you're me. Who should be able to do it and it's a personal failing that I can't

Using an ancient petalinux version on the microzed, issues with tcf agent in vitis. Struggle through a new petalinux build annnndddd…. Vitis uploads the executable to the microzed but still throws an error 😑

No magic smoke! Carrier board went together smoothly. Now need to figure out why the bank power isn’t turning on intermittently (which is enabled by SOM board)… and give it another clean lol
