X5000 Uboot output to serial

Hello,

How do I set Uboot's output to the serial on the X5000? Is it setenv stdout serial, then saveenv? Or is there some other way? I don't have NVSetVAr in my C directory.

Thanks in advance!

I don't know about X5000 but on other systems it's setenv os4_commandline serial then saveenv. If you have a U-Boot menu maybe it can be set from that as well. stdout sets the output of U-Boot not the AmigaOS kernel.

@balaton

Yes I want to set the output of Uboot. I want to see how my memory is being detected. I kind of wish Amiga OS had a CPUZ type of app.

But thank you.

The X5k uboot will use the serial port without doing anything unless it was changed in recent years
Set the communication to:

115200 Baud
8 Bit data
No parity
1 stop bot
No Flow control

Yeah it turns out I had to set stdout to serial. It must have changed at some point.
Anyway. I saw what I needed to see.

Thank you.

@kishigo
Default should beThat way you get the output on both the monitor and the serial port.

@joerg

Thank you. But how should I set that? Should I do setenv stdout vga,serial or is there a way to tell U-boot to use default environment settings?

@kishigo
You can use "setenv stdout vga,serial", "saveenv" to get that result as well.
To delete an U-Boot variable, which will reset it to it's defaults, use "setenv stdout", "saveenv".

Doesn't matter much for "stdout", but it's important for example for the ethernet MAC address(es), the included SD card has it set (at least on my X5000 that was the case), resulting in all X5000 systems using the same value, which is a problem if you have more than one X5000 in the same LAN. If you delete it ("setenv ethaddr", "saveenv") the default is to read it from the hardware which should have a different MAC address for each system.

@joerg

Something must have changed. When I tried "setenv stdout" it said "can't delete stdout". When I tried "setenv stdout vga,serial"
it said "error inserting variable errno 22". It wouldn't let me change it. Oh well. It works.

Thank you!
