[Ovmsdev] Some warning/error messages

I see this too. I’m guessing it is a bug in the ESP IDF version we pulled at last merge.

I enabled the option for MD5 checksums on the partition table, for production builds, and it seems to be working (looking at the generated partitions.bin). It also validates correctly.

I think this is just a facility to disable the generation of MD5 checksums, and the MD5_OPT variable is not set empty when using MD5 checksums. Should not impact operation.

Once the next OTA firmware release goes out, I intend to try another upstream merge for the IDF. Just a bit scary as historically they have broken stuff.

Regards, Mark.
