hello esp Team,

I want to use esp32 module, I want help on wiring so that I can flash the app.

Start here, and go to the schematic link on the page. It will show you how the kits is wired and what you need.

LOL good thing you posted a picture or we wouldn't know what CPU you were talking about!

Be sure to look into GPIO 00 and it's use as a download mode signal during boot. My friend build an Ethernet board and ran the clock into GPIO 00 (the default for ethernet applications). Now the board refuses to boot unless you cycle power or reset it multiple times.

Yup, I did the same thing on my first build. Wound up tieing the EN pin of the OSC to GPIO 2, and then call phy_device_power_enable_via_gpio() during the init process to fix that.
