Default clocks on Nucleo F401RE
I have a Nucleo F401RE board which came with no external crystals
populated for the target MCU. Both LSE and HSE sources are missing.
However, nucleo_f401re_defconfig says
# use HSE as PLL input
It took a while to figure out why the board won't boot. Is my board
bad or some special cheap edition? Owners of this board, do yours have
an 8 MHz crystal populated?
Went a bit further, in ST's UM1724 "STM32 Nucleo-64 boards", sectiontoggle quoted messageShow quoted text
"6.7 OSC clock" mentions two revisions of the board: MB1136 C-01 with
HSE disabled and MB1136 C-02 and higher with HSE from ST-LINK. Maybe
this deserves a note in the docs.
