Wifi dropping and having issues.

[fly135]

Not sure if this is a coincidence and I've only tested with one device so far. When I switched from having one NVS partition to two the wifi on my device started having issues with connecting and dropping on a frequent basis. This isn't a wifi issue overall because all the ones running with the single NVS partition are doing fine. I've attached a boot print showing the two NVS partitions. The line in the partition file for the 2nd NVS is...

secstore, data, nvs, 0x290000, 0x70000

In the boot print it replaces "nvs" with "Wifi Data", so combines with my new problem it makes me wonder if there is an issue with having two NVS partitions or if I'm doing something wrong.

BTW, is "phy_init" needed if you aren't using Ethernet?

I believe I know what the problem is, and it doesn't have anything to do with NVS. At the same time as creating the 2nd NVS I was using a new daughterboard that didn't have a pin clipped on the connector. It was putting 5V on GPIO 00. Not sure if that could cause the problem but I'll know when I clip the pin and retest.
