Comments
This signal is used to reset the CC3235 device. This signal is also output
on the 20-pin connector to reset any external BoosterPack that may be
stacked. The reset can be isolated using the jumper block at the center
of the board.
When pushed, GPIO_13 is pulled to VCC.
When pushed, GPIO_22 is pulled to VCC.
Pressing this button and toggling RESET (SW1) restores the factory
default image on the serial flash. This can be used to recover a
corrupted serial flash, provided the s-flash was programmed with a
recovery image.
Comments
