I have designed a common carrier card for TX2, TX2i and TX1. I have followed the TX2 EV kit C02 schematic(page 19 an d page 20). As per the design, MOD_VIN_EN goes high on a short press and MOD_PWR_ON_CLK pin also makes a transition from high to low and back to high again. But the status of MOD_PWR_ON_STATE and MOD_PWR_ON_STATE_L pins are not changing. It remains LOW and HIGH respectively. Can you please help to identify possible reasons? The status of MOD_PWR_ON_SET is HIGH.
