Beagleboard problem

I have a Beagleboard C4. I used CreateSD to format my SD. I have the orange screen at boot (= everything is OK), then nothing. I tried also system disk, with classic boot and MLO one. Same effect: nothing. Any idea?

Nota: this is not a XM board.

Try a known good SD card image. You do have a backup?

I don’t even have a working OS, so no need for a backup. Where do I find a ready to run SD image? (not on this website).

The easiest way is to flash an RC12a image to an SD card and then put Beagleboard firmware and rom in the fat partition. Or buy a pre-loaded SD card from R-Comp. Or boot from SCSI.

I tried with a Pandora image: no success
I used SDCreate (just to see if ROM boots): the same
I used System Disk: the same

Or boot from SCSI.

It does not boot at all. Orange screen, and nothing else.
And it’s not a problem if MLO file: Beagleboard does not need it.

Not sure it’ll work better.

With a PC running a serial console connected to the serial port what text do you have on the console and how does that match the information on the beagleboard wiki pages?

Sorry. I don’t have serial ports on my RISC OS computers :)

Anyway, I managed to find a working version of Linux (only one worked), with suitable MLO file. As soon as I make a uenv file to load riscos ROM, I got a black screen after the orange one. Nothing else. I begin to think I have the only version of BeagleBoard not compatible with RISC OS :)

Conclusion: avoid BB Rev C4 for RISC OS.

Right, so you deliberately don’t connect the diagnostic port. Oh well.

(Ignore this, I realised my suggestion had already been tried)

I could, but to what? :)

Something doing a VT100 emulation. I’m pretty sure there’s an emulator in the hensa archive under comms.
At a setting of 115200, 8, n, 1 it tends to display text sent from a serial diagnostic port.

Not sure why the board has 115200 as the speed, but there you go.

Ok, I’ll try

Hum. “I don’t have serial ports on my RISC OS computers”

… work in progress… ;-)
I have uploaded the content of my BBC4 Loader-Dir.
BBC4only!

SerialDebug:
I use a FTDI USBtoSerial Adapter, Thomas FTDI Driver for RISC OS and Neddle…
So I have a RISC OS only solution ;-)

You have a Pi. You just need a level convertor as the Beagle uses real serial not 3.3V. Or maybe you could see if it is possible to hook in prior to the… what would it be, a MAX3232?

Or use a non-RISC OS computer to view the trace?

You have a Pi.

Not he same as you :) Mine is in a closed cartridge for use with the Lapdock (thanks Raik!).

This could be a solution, yes.

Not at home…

My BeagleBoard has been on loan for a while now, so I can’t see what version it is. Whatever version it is, it always worked fine with RISC OS.

It’s a c4 and it works fine – finally got an ax88772 ethernet adapter working without sharefswindow 1 but that’s another story.

The sd card is just fat formatted with the boot files on it and riscos is booted from a separate memory stick. I have found that it is a bit picky over how I change the rom on the sd card. On the pi I can copy the rom to the boot partition over the network and just restart. On the beagle I have to use a card reader on the remote machine instead of copying via the network and you must remember to dismount the card before inserting it into the beagleboard otherwise it can stop at the Orange screen.

I wonder if that sounds familiar?

This is not the same case here (Linux works fine with a SD card made with the same tools).
I suspect some problem with case of filenames, or with the internal bootlader (updated to a very recent version, that forces you to use MLO files to boot the card).

I not need a MLO file to boot my BBC4. Only a boot.scr + CMOS + ROM.
Maybe you need this tool from Jeffreys page at first.

Yes, perhaps. I’ll see. Thanks Raik.
