iMX6ULL UART5 does not receive - Header file bug

Hi All,

This is just a knowledge share. We are in the process of bringing up a new board and noticed that UART5 would not receive on the UART5_RX_DATA pin. I tracked this down to the UART5_RX_DATA_SELECT_INPUT DAISY register being incorrectly set as 5 instead of 7. This is because the imx6ULL-pinfunc.h file inherits from the the imx6UL-pinfunc.h file which requires this register to be 5 instead of 7. Simple fix is to add the following to the imx6ull-pinfunc.h

#define MX6UL_PAD_UART5_RX_DATA__UART5_DCE_RX 0x00C0 0x034C 0x0644 0x0 0x7

Thank you for sharing your insights. I'm going to raise a ticket to the software team to fix the issue.

Best Regards,
