Is there any limit to the size of the SD card or file system partitions on the beagle bone (or any other beagle board)?

8 Gig is the size limit for an SD card on the CraneBoard. I believe
that the BeagleBoard has the same restriction. When I try to boot a 16
Gig SD card on the CraneBoard, it reports unreadable sectors while
booting. 8 Gig works perfectly though.

What's the reason for the size limit?

I can only surmise that the crappy card reader on the CraneBoard is
missing some lines or that the embedded load created on Narcissus can
only handle a certain number of cylinders (remember that when you FDISK
an SD-Card, you are required to make it 255 heads, 63 sectors/track in
order for it to boot). The BeagleBoard may be different from the
CraneBoard, but my experience with a 16 gig and 32 gig SDHC card was
that the thing would read MLO, u-boot.bin etc but screw up as soon as it
tried to read the Linux ext3 partition.

Also remember that the BeagleBoard's and CraneBoard's video output is
restricted to 1400x1050 resolution because of the TI Sitara chipset
restriction

I use a 16GB microSD card with Ubuntu 11.10.
The only problem I had yesterday was with reboot/reset, no output on
terminal nor did it boot as I couldn't ssh to it.
Tried for over an hour then it booted, eth0 came up with the IP address
assigned via dhcp, R229 had been removed when first recommended and
everything was normal.

This time only /dev/ttyUSB0 showed, before both ttyUSB0 and 1 were there
and serial console was available using ttyUSB1.
Serial console is still running on 0, now /dev shows no ttyUSB devices.

May be it needs a reboot as a new kernel came with the latest upgrade.
# ls /lib/modules/
3.1.0-psp3 3.1.6-x6


The system is going down for reboot NOW!

It stalled there and I had to use RESET key. It rebooted on the original
3.1.0-psp3 kernel and is up using ttyUSB0.

I got the same with a 32GB card on the XM but both the XM and BeagleBone are using 16GB Class 4 cards.

Sid.
