One issue we are having is that if power is lost to a board which is connected to a busy WiFi access point, the chance of a file system corruption is 50/50 requiring a reflash of the eprom using a USB stick. Since this is the same OpenWRT as used in commercial routers that never have power loss file system corruption, I am wondering what I can do to avoid this situation. If the board required a micro SD card to operate properly, and had a version of OpenWRT that did not write to the eprom, that would likely avoid any possible corruption. Looking for a solution that doesn’t require additional circuitry to aid in a clean shutdown on power loss. Thanks, Shannon Bailey of (IOTInventor.com) and (MakeSchool.com)
