Hello, I have an PXA270 bord with U-boot version 1.1.2 (Dec 22 2005 - 09:10:28) I want to change the file stream stdin and stdout to the serial COM port 2, now its on COM1 I tried with

-setenv stdin serial1 -saveenv

also tried with

-setenv stdin=serial1 -saveenv

but no luck. The file stream is always COM1. Can you gibe me a hint? Best regards

As a very first step you should try finding out which I/O devices are configured on your system. What does the "coninfo" command print?

Hi Wolfgang, the coninfo shows this:

List of available devices: serial 80000003 SIO stdin stdout stderr nulldev 80000003 SIO

I suppose this is why I can´t add the second serial, how do I add the COM2 ? Bets regards Javier

Right - when there is no other device configured, you cannot switch to another device...

I don't know if this feature is supported for yoru architecture and/or your board. Check the configuration...

Hi Wolfgang, the hardware definetely supports the COM2 (I tested it with Windows CE 5.0), but how can I add/configure the COM2 with U-boot ? Is 80000003 a memory adress? Best regards Javier

No, its flag bits. Please RTFM and the code.

Hi Javier,

Hi Wolfgang, the hardware definetely supports the COM2 (I tested it with Windows CE 5.0), but how can I add/configure the COM2 with U-boot ? Is 80000003 a memory adress?

On the PXA270 you have three different UARTs, FFUART, BTUART and STDUART. I don't know what your configuration looks like, but I am pretty sure that what you dub as "COM1" is the FFUART and the other UARTs are not even supported let alone dynamically switchable in U-Boot.

Fortunately we are just working on something like this, Stefano (on CC), should be able to tell you when this will be finished.

Cheers Detlev

Test is finished. I will send the patch. Multiple serials are supported in the same way as they are on the PPC boards.

Javier, at the moment u-boot supports only one serial interface and consequently you cannot enable the other ones. You can use any of FFUART,BTUART or STUART, but u-boot cannot have more than one serial at the same time. The serial driver for PXA27xx does not support it.

After applying the patch I will send, you have to set CONFIG_SERIAL_MULTI in your config file and all serials you want to use:

#define CONFIG_SERIAL_MULTI #define CONFIG_FFUART 1 /* we use FFUART on Conxs */ #define CONFIG_BTUART 1 /* we use BTUART on Conxs */ #define CONFIG_STUART 1 /* we use STUART on Conxs */

You have to provide also a function in your board.c file to return the default serial device, such as:

struct serial_device *default_serial_console (void) { return &serial_ffuart_device; }

or whatever you prefer.

On my target (PXA270) I get: U-Boot 1.2.0-gc7d2ba2d-dirty (Aug 23 2007 - 15:47:09)

DRAM: 64 MB Flash: 32 MB In: serial Out: serial Err: serial Hit any key to stop autoboot: 0 $ coninfo List of available devices: serial 80000003 SIO stdin stdout stderr nulldev 80000003 SIO serial_stuart 00000003 .IO serial_btuart 00000003 .IO serial_ffuart 00000003 .IO

Then you will be able to switch among the serials setting the stdout, stdin and stderr variables. For example, to switch to the BTUART:

setenv stdout serial_btuart setenv stdin serial_btuart
