@jerpelea i won't until i understand why it should be (2 *

@jerpelea
there seems to be multiple clock sources available for CPU clock.
see esp32_technical_reference_manual_en.pdf 3.2.3 "CPU Clock"

@jerpelea why do you think it should be 2 * BOARD_XTAL_FREQUENCY?
my understanding is that it should match the bootloader, which seems to

do you mean non-CONFIG_SUPPRESS_CLOCK_CONFIG code can work? i don't think it
even compile.
i agree it's better to fix it though.

my thinking is that
* the current code is broken at least if you run nuttx with esp-idf

@jerpelea
sorry, i don't understand your comments.
do you mean that, for some reasons, BOARD_CLOCK_FREQUENCY should be same as

CONFIG_ESP32CORE_XTAL_40MZ is about BOARD_XTAL_FREQUENCY.
this change is about BOARD_CLOCK_FREQUENCY.

@jerpelea
it's about BOARD_XTAL_FREQUENCY, isn't it?
this 80MHz is hardcoded in the bootloader. see the code referenced by the
