Here are some "best practice" tips to assist with the firmware upgrade process. These ensure that memory utilization is at its minimum on the node. The upgrade process can fail due to lack of memory, but such a failure will leave the node unchanged on its previous firmware version.
* Before starting the firmware upgrade, it may be necessary to uninstall any packages you have manually installed (for example, MeshChat or IperfSpeed).
* Disable any existing tunnels on your node before starting the firmware upgrade.
* Reboot the node immediately before starting the upgrade.
* Use a stepped approach to firmware upgrades. For example, if your node is running version 3.16.1.0 you should probably upgrade to version 3.18.9.0 before attempting to apply a newer version.
Before starting the firmware upgrade, it may be necessary to stop, disable, or uninstall Meshchat, hamchat, snmp, and any active tunnels. The goal of this step is to keep those processes from using RAM memory and to free as much RAM as possible before the upgrade. Rebooting the node will ensure that its RAM utilization is at a minimum.
Use a stepped approach to firmware upgrades. For example, if your node is running version 3.16.1.0 you should probably upgrade to version 3.18.9.0 before attempting to apply a newer version.
