i.MX287 How to use the DUART as an application UART?

[chaoye]

Hi All,

The processor i.MX287 has one Debug UART and five application UART, but now we need six application UART, so my question is how to use the DUART as an application UART? If there is any solution, how to configure the DUART register?

Best regards,

one can see the debug uart pins are defined in the mx28evk_pins.c(arch/arm/mach-mx28), so now you don't need any debug uart?

let me remind, DUART doesn't have the same performance as AUART.
