running ESP32-D2WD at 240 MHz ??
Posted: Sun Jan 13, 2019 9:11 pm
Hi ESP32 community,
I am new with ESP32 (changing from STM32F7 / H7) and I am wondering if it is at all possible to run ESP32-D2WD at 240MHz. The data sheet specifies max 160MHz, but possibly this is only because of the embedded Flash?
I am thinking of "booting" at 160MHz, copying executable code from flash into on-board SRAM, and *afterwards* (when already executing code from SRAM) changing to 240MHz. Of course I will "never" touch the flash memory again.
Any thought? Any experience here?
I am asking, as for a current project I need to minimize the size of the chip (5x5mm with internal flash) and maximize CPU speed. So I can not afford using ESP32-D0WD (specified up to 240MHz) with external flash.
Thanks for comments! Jorg
