I am getting the similar error while building.
unrecognized command line option '-mfix-esp32-psram-cache-strategy=memw';

my xtensa-esp32-elf-gcc version is 8.2.0

@manmohan777 What is the full output of xtensa-esp32-elf-gcc --version, please? This flag was introduced in 2020-r1 toolchain release, you might be using an older version?

Same issue here on release v4.1 after doing a pull and submodule update init & recursive:

Not sure if it's the right thing to do but setting the following in menuconfig seems to have fixed the compile issue and my code appears to be running normally...
