Hi fellow barebox users. What a great loader, thanks to all of you for
sharing your work on this.
I've brought barebox up on a custom at91sam9g45 board that has both NOR and
NAND flash, and one SD card connected to the MMC interface. I was previously
using all these with an older version of u-boot and in Linux, so I am pretty
sure that the hardware is working properly.
For some reason, I can't access any files on a 4G SD card. After booting
into barebox, there is a /dev/disk0. I can mount it without error, for
example mount /dev/disk0 fat /mmc. But ls /mmc does not show any content,
and I know that there are many files there. The card is not partitioned.
Have I overlooked something ? If not, any suggestions where to look for the
cause of the problem ?
George

Sorry, barebox currently can't access anything > 4GB and some pieces may
have problems with 2GB. Please try either a smaller SD Card or add
partition your SD card and add a partition smaller than 2GB.
This is being worked on. Hopefully we have support for bigger SD cards
soon.
