Okay, read the old article and realised my mistake! OOOOPS !!.
(putting those files into the root is needed when creating a NEW SD card.)
Found the .BIN file @ https://iotawatt.com/firmware/bin/02_06_02.bin and downloaded
(Had to hack the URL to get this file as I could not find it on the iotawatt.com site by just by looking around. The old article referenced firmware/bin/02-05-09, so I just changed the end of then URL to 02-06-02 )
Copied to “download” folder and then ran the update command http://iotawatt.local/update?release=02_06_02
All good !
SD initialized.
