Hi,
I am using openwrt ( OpenWrt 18.06.0 r7188-b0b5c64c22 / LuCI openwrt-18.06 branch (git-19.324.23087-ab9c812) on espressobin v5 (booting from sd card) on a remote place for 1.5 year.
It's been more than a month now that the power at place is unstable and with 5-6 power losses per week.
For some reason since last month, I can access (ssh or luci) openwrt on espressobin only after every second power loss.
During the first power loss, I can't access openwrt but internal espressobin switch works as I can access an ip camera connected to the switch. I only use the lan ports not the wan port and I have one usb to rs485 converter hooked on one usb port.
Could anyone help me debug - solve this issue?
I attach dmesg and uboot env.
Dmsg
