ESP32 chip Revision

Postby Die_32_ » Fri Nov 19, 2021 9:24 am

Hi all,

I have different ESP32 module with different chip revision ( 1,2,3 ).

When I build my project I can select the minimum chip revision for the .bin file or app file.

If I put min rev 1, I understood that it will works without any problems also on rev 2,3, correct ?

It should - we used for ages min rev1 on an actual rev3 silicon for various reasons.
One footnote that it changes the "strategy" of SDK config options, so changing this option can cause eyewatering number of config flag changes, as many are inter-related (e.g. secure boot modes etc.).
