IMX28 Pin Configuration

Hi

We have MCIMX28EVK board and a board with imx28 (designed by us).

We are using freescale L2.6.35_1.1.0_130130_source.

Our board uses AUART0 pins for debug uart.

I have seen the debug uart pins are defined in mx28evk_pins.c( /arch/arm/mach-mx28 )

 

static struct pin_desc mx28evk_fixed_pins[] = {

{

.name = "DUART.RX",

.id = PINID_PWM0,

.fun = PIN_FUN3,

},

{

.name = "DUART.TX",

.id = PINID_PWM1,

.fun = PIN_FUN3,

},

 

...

...

...

}


I am using AUART0_CTS and AUART_RTS as DUART_RX and DUART_TX.


So I have edited the struct like the following



static struct pin_desc mx28evk_fixed_pins[] = {

{

.name = "DUART.RX",

.id = PINID_AUART0_CTS,

.fun = PIN_FUN3,

},

{

.name = "DUART.TX",

.id = PINID_AUART0_RTS,

.fun = PIN_FUN3,

},

 

...

...

...

}


Is this change enough for the imx board?


Regards

Pt
