BeagleBoard-xM ready to go SD card image won't boot

I’ve recently got a BeagleBoard-xM rev C board.

When I tried using the pre-built SD card image I downloaded via the links
in the wiki with my native RISC OS hardware boot stick it wouldn’t boot.

After mounting the SD card I could see that the image had MLO and U-BOOT.BIN
which are different to those in an image I recently generated for booting Linaro Ubunto 11.10
on my BB-xM – after copying MLO and u-boot.img from my image and re-starting
RISC OS booted fine. My MLO is considerably larger than the one in the pre-built image and apart from
the name change (and case change) my ‘u-boot’ is also considerably larger.

Its great to have a working RISC OS system again.

I’m currently using 3 of the BB-xM USB ports for Keyboard, Mouse and boot stick – if I
plug a USB disk in the 4th will the RISC OS rom I have support it?

Maybe it’s a rev.C issue. Those images are pretty old now! Glad you got it working though. You could try uploading your image for others to try on previous board.

AFAIK it should do because it just functions as an onboard USB hub.

I had a problem getting mine to boot at first. I created the SD card image using SDCreate on my Iyonix. The problem appeared to be capitalisation of the filenames.

I happened to have Fat32FS running which appears to changes the case of the first letter of the file name and the case of the extension of the file so file.JPG becomes File.jpg

I rebooted my Iyonix without Fat32FS and was able to create a working SD card first time.

Maybe I have got his all wrong wrt to Fat32FS but that was the solution that worked for me.

If anyone else fancies confirming these errors, the relevant page is Ready-to-go SD card images. Perhaps it should be renamed “Ready-to-catch-you-out SD card images”!

Both MLO and u-boot do appear to have been updated for various board versions at various times.
I also checked what was in a few linux images.
Depending on when the images were generated the MLO and u-boot are of various sizes which would be
expected as newer board revisions are introduced.

On my MAC I ran strings on each MLO. The MLO I have supports rev A, rev B and rev C of the BB-xM
whereas the one in the pre-built image only supports rev A.
Another strings shows that the MLO in the pre-built image expects u-boot.bin
whereas my newer MLO supports both u-boot.bin and u-boot.img.

So it looks like there are two possible issues, the first being that MLO and u-boot have been updated and the second that
U-BOOT.BIN should be u-boot.bin. A further strings on the original pre-built SD card image shows that it contains U-BOOT.

I’ve added a new note (3.) to the images page.

Mm, that’s right. I had to use the version that came with my revision C rather than the one here.
