Hi

The following is the gist of issues seen,  namely

 1. unable to saveenv
 2.  ubiattach issue.

I am using NAND device: Manufacturer ID: 0xec, Chip ID: 0xda (Samsung
NAND 256MiB 3,3V 8-bit).

Please help

Hi

Changed nand_chip_delay =50 from 20 in
./drivers/mtd/nand/atmel_nand.c, and presently getting:-

barebox@Atmel at91sam9263-ek:/ ubiattach /dev/nand0.root
UBI: attaching mtd0 to ubi0
UBI: physical eraseblock size:   131072 bytes (128 KiB)

UBI: VID header offset:          2048 (aligned 2048)
UBI: data offset:                4096
registering /dev/ubi0
UBI: attached mtd0 to ubi0
UBI: MTD device name:            "nand0.root"
UBI: MTD device size:            254 MiB
UBI: number of good PEBs:        2028
UBI: number of bad PEBs:         5
UBI: max. allowed volumes:       128

UBI: number of internal volumes: 1
UBI: number of user volumes:     0

UBI: total number of reserved PEBs: 24
UBI: number of PEBs reserved for bad PEB handling: 20
UBI: max/mean erase counter: 1/1

But further giving a

barebox@Atmel at91sam9263-ek:/ tftp rootfs1.ubif /dev/ubi0
TFTP from server 192.168.0.110 ('rootfs1.ubif' -> '/dev/ubi0')
        write: No space left on device

tftp failed: error -28

Btw , which is the irc channel of Barebox?
