Hello! I'm using an ESP-32 Cam board, and trying to get the CamWebServer example to work on it with the Arduino IDE. I don't have an adpater for USB so I've connected it to an Arduino Uno like you can see in the png attachement to this post.
When I click to upload the code to the board, I get the following error:
A fatal error occurred: Failed to connect to ESP32: Invalid head of packet (0xE0)
I saw some people suggesting to hold down the button on the ESP-32 Cam board while I upload, but that doesn't do anything for me.
Please help, because I haven't found a good solution for this problem yet!

A few things
1 - check your voltage out of your uno,
2 - it looks like you're using the 3.3v, mine would only program in 5v using the adjacent 5v ground pin
3 - hold reset button and let go when you see the ellipses in red print, mine will only flash while booting.
4 - make sure you connect pin 0 to ground to enable flash
P.s.
You can get a breakout board for like $4, I use the ft232rl
