I would do the opposite using the OTA component. Put the new firmware "anywhere" that can be reached by your ESP32. To update press a button on your thermostat and activate automatic update ESP32 goes to "knock" where you put the new firmware download and update with the new firmware. You make the ...

I am working with ESP-IDF 5.1.1, although that's probably not relevant. Right now I have a project [1] that is providing a function to update the firmware via the web server. I know this is not secure and not recommended, but it is also not relevant to my question. My question; once the firmware upd...

Thank you for the help here! After instrumenting the code to show the amount of PSRAM and coaxing PlatformIO to build without support for PSRAM, it now works fine. There was also a problem with getting the right pins to be configured for SDA & SCL. A logic probe cleared that up. This is the problem ...

Sorry, my mistake; it is the R8 variant. So the original question still remains - is there a way to disable the internal PSRAM so we can test the proto boards we currently have?

First time here and somewhat new to ESP32, especially S3. I recently designed a board and used the ESP32-S3 as the MCU. The problem is when I created the BOM the wrong part number got used and I have prototype boards with the ESP32-S3-WROOM-1-N16R2 instead (contains onboard PSRAM). This is causing p...
