6.10 Reset & Wake-up Buttons
6.10.1 Reset Button S2
The push-button S2 is used to generate a reset to the STM32MP157 processor and the peripherals
on the SBC.
The push-button S2 is connected to the
RESET_MICO
signal at pin-17 of the emSTAMP-Argon
module. By pressing S2 the
RESET_MICO signal is pulled low. T
he
RESET_MICO signal has a 10k pull-up
resistor which is equipped on the emSTAMP-Argon module.
