Hi,

I'm having problems with the firmware.
I have tried an checkout that is a couple of weeks old and also one that checked out yesterday. My uBoot version is 1.1.6 (not that it should matter to much:))

After i flash the device and it boots up I dont get a persistent filesystem. But only a /dev/root.

And in dmesg i can see the following errors:

<5>UBI: attaching mtd3 to ubi0

And when i boot the system it seems to clean and format the nand. because i get the following messages:

My device has a 512MB NAND memory. but only now trying to allocate 256MB, since this is the standard for the BR4. Havent really made the simple necessary changes for that yet

I will dive more into this laster today. But thought i post it here to see if any of you guys have any inputs on this?
