[SOLVED] - ESP-WROOM-32 flash fail

I finally figured it out! Even though it does not make sense to me at all. If I use a CP2104 as USB <-> UART instead of the FTDIs, it works fine. I do not really understand why, because both operrate at 3.3V. Since I could use the FTDIs for monitoring and to flash other devices, the driver is fine a...

But I had that idea as well and monitored the voltage while flashing. It remains between 3.29V and 3.31V. I also pluged in the FTDI into the ...

ESP-WROOM-32 flash fail

Hi there, I am trying for a few days to flash my ESP-WROOM-32 via FTDI and I do not know what I am doing wrong. Please have a look at my "setup". I am grateful for any advice. If I try to flash the DevKit-Board (on COM6) it works just fine. So the esp-idf shouldn't be the problem. http://www2.pic-up...
