Re: spi_flash size warning

It means that your software setup assumes you have a 2MiB chip (as indicated under make menuconfig, serial flasher settings, iirc), but your actual board is lucky enough to have a 4MiB one. The warning is just that, a warning to show you your software won't be able to use the other 2MiB that exists ...

Re: Module shutting down when wifi is used

Check your USB lead then. A fair amount of cheaper (and some non-cheap) USB leads have thin cables, leading to voltage drop and brown-outs.

Re: COMPONENT_EMBED_FILES & Cmake esp-idf-v3.2.2

Interesting - it's almost as cmake defines an index_html symbol when including the binary. Can you see what happens if you rename the index_html variable in your code to something else?

Re: RAM & Flash cache efficiency

No, sorry, the ESP32 does not have a prefetch mechanism to my knowledge.

Re: SW_RESET continuous reboot

Hard to say... does the module still do this if you supply it with an external 3.3V source?

Re: esp32 and ws2812b blinking crazy

Are your grounds all connected? If not, can you draw out how you have connected everything?

Re: Socket for echo server on ESP32-WROWER-B module in access point mode

I don't get your issue? The ESP32 is 192.168.4.1, the Win10 machine is 192.168.4.2, so if you want to connect to the ESP32, you should connect to 192.168.4.1. If you connect to 192.168.4.2, you will try to connect to a server running on your Win10 machine.

Re: Is it possible to do car plate recognize with ESP32-camera?

With the hardware? Probably. We don't have example source code for this, however.

Re: ESP32 resets on mechanical shock

Theoretically, the only other thing I can think of is ceramic capacitors that are microphonic... theoretically, for instance, if the cap on the reset line had this really really bad, it could reset the chip. I doubt that this is the case, it's more of a problem in analog circuits.

Re: ESP32 resets on mechanical shock

Strange. Perhaps one of your connectors is a bit wonky, and the acceleration makes it loose contact?
