WebMay 6, 2024 · The generic one is hard to tell since the microcontroller is inside a metal shield. If the ESP-32 has no on-chip flash storage (at all), then even the generic ones should have it externally. If they have, then the external one it's just for expansion. Remember that the ESP boards divide the flash memory in four sections (as the Arduino IDE is ... http://www.microsin.net/programming/arm/esp32-c3-use-spi-flash-pins-as-gpio.html
WebThis parameter can also be specified using the environment variable ESPTOOL_FM. Most ESP32 modules use qio, but are also dual I/O. In qio mode, two additional GPIOs (9 and 10) are used for SPI flash communications. If flash mode is set to dio then these pins are available for other purposes. WebJul 23, 2024 · And strangely this was not the problem a week ago, everything was working fine and I checked my terminal logs from a week ago (which I saved in a separate text file because of some other error) in that I (54) boot: SPI Flash Size : 4MB is written. So this changed automatically I guess because I didn't change anything in the menuconfig.
