Hello,
Environment:
ESP32 wrover (dev board) / ESP32 wroom / working arduino environment on Win7/64 bit.
Symtoms:
Script flased on a ESP32 wroom are executed (for example simple blink)
Scripts can be flashed on ESP wrover module, but seems not to be executed (no blinking led .
IDF_SDK blink sample runs on ESP32 wrover.
Question:
Is the flash speed set via arduno bootloader always set to 80MHz?
As I read in an other thread, flash speed of 80 MHz causes trouble on dev board.
If yes, can bootloader used by arduino environment be modified (patched)?
thanks in advance,
Gunter

Re: Arduino Env. and ESP wrover
I think the 80mhz in bootloader means the CPU Clock.
The problems with 80mhz is when the SPI connected PSRAM is clocked at 80mhz. (or so i've read)

Found it by myself...Just set 40MHz in Tools...Flash frequency...

You can set in on Arduino menuGunter H wrote:Is the flash speed set via arduno bootloader always set to 80MHz?
I also heard that the flash of wrover (module) doesn't work in 80Mhz
