Can’t input angthing after booting…

Hi,r
I have a clone beagleboard, and tried to install linux on it. But, whatever I was installed, Angstrom, Ubuntu or a linux built by myselft, I can’t input angthing by minicom or other terminal software.I can’t stop autoboot, can’t input the bootcmd, can’t type user and password.

But I can see the output of the board!

There is no dvi interface on the board, and network didn’t go well.Although it have a TFT LCD, but in general system didn’t support it.

I put some boot infomation in the attachment.The attachment infomation based on ubuntu release https://rcn-ee.net/deb/rootfs/raring/ubuntu-13.04-console-armhf-2013-09-26.tar.xz .

Thanks.

Which board did you copy?
Is your schematic correct?
Is the PCB layout correct?

Gerald

So you "cloned" a board, added a TFT LCD and just "expected" my image
to work.. Show us the Schematic's, otherwise you are on your own..

Regards,

I don’t see any bugs in the bootlog

Disable HW-flow control for your RS232 connection and try again

Hi,

It’s a chinese BeagleBoard clone.I didn’t clone the beagleboard by myself.
I don’t kown which the board cloned.And HW-flow was disabled.
No matter the TFT LCD, I just want to be able to enter the username and password by serial…
I put schematics in the attachment.

PS:my english is not very good…

Thanks.

Not a very good clone. The processor is missing. I assume there is more to the schematic, maybe?

Gerald

I'd contact the manufacture of the "Clone"...

Regards,

e… no more schematic, the processor is omap3530.

it kinda reminds me of that devkit8000, beagleboard knock off.. Looks
like it only has OTG usb, do you have the right usb adapter/usb
hub/etc?

Regards,

In fact, It has no OTG usb on the board.
Because of no HDMI interface, even if it has OTG usb and I can input by using keyboard.
I also can’t see what I type in. So I have to use the serial.
