Hi all,

 

The board use AUART0_CTS as DUART_RX, AUART0_RTS as DUART_TX.

 

Set the board boot from usb otg mode,and connect to PC which installed Ubuntu14.04.Then Ubuntu can identify one HID FSL device.

 

I use mxs_ldr can download u-boot.sb file.If use the .sb file from version u-boot-2009(other person porting),there are normal prints in duart.

 

I don't know how to set USE_ALT_DEBUG_UART_PINS to 01 in u-boot-2014.If I only change DUART pinmux in the file iomux.c,the debug console is also no prints.

 

Can you help me fix this problem(duart no prints)?

 

Best Regards & Thanks!

Eason
