FS errors

Build and tried - first was getting brown-outs so I added a 5V PS.

Now I keep getting "W (2269) vfs_fat_spiflash: f_mount failed (13)"

It can't mount the file-system. Does it need some external memory?

Tried it on two different ESPWROOM32, ESP32D0WDQ6 (revision 1)

Found the problem. I had to make and flash the FS, and one of the utilities in the download would not run (mkfatfs). Cloned the ESP32_mkfatfs project and re-made the utility, then copied the utility to the directory path expected.
Then, did a 'make makefatfs'
and a 'make flashfatfs'

Now I don't get the f_mount failed message, instead I get a listing of the contents of the spiflash.

At first my phone still won't connect to the web-site but then I reread the instructions (dua, it says right there to run "make flashfatfs") and it says to go to 192.168.4.1 and that worked!

THANK YOU for making this available!!!

Glad you got it working 👍
