i.MX6 serial - irda

[JHY]

IRDA setting is as below in IMX6DQRM.pdf.

IREN(UCR1[7]) is findable in imx.c (drivers/tty/serial/) but MDEN(UMCR[0]) is not.

How can I access UMCR regster in linux?

Hi JHY

UMCR uses default value (uart), for RS485 support

to the imx serial driver one can look at

http://www.spinics.net/lists/linux-serial/msg15795.html

for accessing registers one can use memtool

Reading IPU registers with memtool hangs.

Best regards

igor
