Figured I should update the firmware on my Zigbee coordinator stick. Still attached to my pi-cluster so… Found this docker approach https://www.zigbee2mqtt.io/guide/adapters/flashing/flashing_via_cc2538-bsl.html?fbclid=IwAR30bhQSMBWQ82gyIR3tewr0VUktJWETEUjWFt_pSznuYe8yj0veOWEJyCw#method-with-docker-linux-only

Since I don't have docker on my pi host I did it as a k8s job. First time I updated firmware via k8s :D
