Hi,
I am facing problem with reading the value of the pin when it is configured as GPIO (input) on the Expasion Connection pin McBSP1_FSR (configured to GPIO #157 in uboot). The value returned is not changing irrespective of the voltage input i.e., 1.8V or GND. If i configure the same gpio#157 as “output” I am able to toggle its level to HIGH and LOW properly. Problem is only with reading in input mode.
Other configuration i did on the system -
Taken McSPI4 (master mode) on P9 (Expansion Connector); the SPI signals are fine as I am able to communicate the external slave processor.
What could be the reason for this behavior?
Below is software information
