I am using IMX6Q processor on my custom board.
I am trying to configure one of the UART port in LINUX kernel.
After configuration i am getting 2.8V on TX pin instead of 3.3V and 3.3V on RX pin.
I am using 3.3V on NVCC_EIM power domain for UART.
UART_TX: SRE_FAST, DSE_DISABLE, SPEED_MED, CTL_HYS.
UART_RX: SRE_FAST, DSE_DISABLE, SPEED_MED, CTL_HYS, CTL_PUS_100K_UP, CTL_PKE, CTL_PUE.
Above configuration are used by kernel as a pad value of device tree node.
What could be the cause for this issue?
