Hello,
on updating only ubl from 1.5 to 1.65 (u-boot, linux kernel are both the same as previous)
We get that errors on trying to write into nand from linux.
But I write only filesystem partitions not on ubl partitions , so why do we get this errors ?
# tftp -g -r ramdisk.tar 192.168.1.114
mkdir /mnt/nand
flash_eraseall /dev/mtd3
mount -t yaffs /dev/mtdblock3 /mnt/nand
cd /mnt/nand
tar -xf /root/ramdisk.tar
# mkdir: cannot create directory '/mnt/nand': File exists
