How does the ESP32 core execute code from the serial FLASH ?
Is there a web page that describes how the ESP32 core, executes code from a single serial FLASH chip ? What does the timing look like during execution ? How is a single FLASH chip shared between the two ESP32 cores ? I have seen diagrams with a serial FLASH and a serial RAM connected to the same pin...

Re: BasicOTA and OTAWebUpdater hangs
I found my problem, maybe helpful for someone else. This project is to have an SD Card for the next part of this project. I wired the SDCard socket and inserted the SDcard. When I remove the SDCard, everything works ?!? So, somewhere the VSPI pins are used for something not listed in the source file...

BasicOTA and OTAWebUpdater hangs
I learned about these OTA*.ino files last week. I loaded them up, but after the message "Booting" they both just hang. I had a problem with the compiler complaining, so I removed ESP32_Arduino and reinstalled it via the "Boards Manager". Both now compile but hangs ?? Is this a known problem or may t...

ESP-WROOM-32 & SDMMC & CH340G
I need some advice. I have designed a PCB using a ESP-WROOM-32 & SDMMC & CH340G. The problem is that the CH340G uses the two transistors for set the programming mode. If I have an SD card inserted into it's socket, the WROOM will not go into programming mode. I release the SD card, and its fine. Is ...

printf baud rate ?
I have downloaded PlatformIO and have set it up for ESP32. I loaded hello world and it has compiled and programmed my Sparkfun ESP32-thing board. The LED is flashing but the serial serial monitor shows nothing but junk. I tried to connect Teraterm to find the right board rate, but nothing works. So,...
