Bootloader with auto Flash/SPIRAM speed settings

Postby shodan8192 » Wed Apr 13, 2022 7:56 pm

Hello,

Is this possible to modify bootloader code that way, to have runtime detection that Flash and SPIRAM can be run in QIO mode with 80Mhz clock, then set it or fallback to DIO/40Mhz ?

The goal is to have one firmware for different boards with fastest possible IO on each.
