Re: Mainstone III Serial Port problem

Tech-Archive recommends: Speed Up your PC by fixing your registry

Concerning the first problem, if your software command succeeds it is
probably

1) the FFUART TX pin which is not configured as alternate function UART
or
2) HW switches on the board, maybe the data is not routed to the
connector you're measuring.

How are you measuring anyway? On the pin or using hyperterminal on you
pc? In the second case a lot more could be wrong.

I am using Mainstone III borad for developeing a BSP. And i am using the
latest BSP for mainstone board fom Microsoft. The problem I am facing is,
the serial port is not working with this.

The only one COM port supported is FFUART(COM1). But if i try to write
someting using COM1,(using a seperate application) I am not able to get the
data in the FFUART Tx pin.
It looks like COM port opening and "WrireFile" is success. How can I make
the
FFUART work with mainstone board.

Also I have tried to add a second COM port with with BTUART. i have added
the following registery setting for that. But the kernel is not even booted.
It is waiting with the following message in the debug window.

How can i add all the 3 COM port possible with PXA270
