How to define UART 4 and UART 5 for MQX

[MehmetAliIpin]

Dear community,

When I want to use UART5 of Vybrid VF3, I could not see its definitions

• SCI_FLX5_IPP_IND_SCI_TX_SELECT_INPUT
• IOMUXC_SCI_FLX5_IPP_IND_SCI_TX_SELECT_INPUT

in MVF50GS10Mk50.h, like UART1, UART2, and UART3.

How should we define it?

Best regards.

Hi Mehmet,

You would need to define these based on your custom hardware. You would need to modify IOMUXC_MemMap and add new macros, based on IOMUXC_SCI_FLX1-3 macros. Keep in mind the IOMUXC_MemMap struct ordering - you will want to ensure the register offsets you define match your hardware.

Also, you should add cases for UART4-5 in the _bsp_serial_io_init function, found in the init_gpio.c in your BSP source. For the Vybrid Tower, this is found at mqx/source/bsp/twrvf65gs10_a5/init_gpio.c.

Thanks,
