I have an Adafruit HUZZAH32 Feather which I have flashed clean with JTAG. I wanted to restore for Arduino use, how is this done?
I was thinking you can use the 'ESP32 DownloadTool' in the Espressif Flash Download Tool v3.4.8, is this possible?

Re: Looking to restore Arduino to HUZZAH32 Feather
it is as simple as building and flashing with the arduino ide. No need for the download tool

Re: Looking to restore Arduino to HUZZAH32 Feather
My goodness, it was just that the speeds were too high.
Original: 921600/80MHz
Working: 115200/40MHz
Thanks for the input and the nudge, now I am back up and running!

Speeds are interesting. I am running with 95% first time flash using 921600. I am using 12 inch USB cables between my ESP32s and a powered USB hub. Just an FYI.

Re: Looking to restore Arduino to HUZZAH32 Feather
it really depends on the board.
On my DOIT I can do 921600 when it's cold, when it is warm it fails 2 out of 3 times.
My Pycom lopy can handle 2m baud, 80mhz QIO flash. Hooked up on a 3m very old usb cable. And has never failed me.
