Wolfgang,
I do have ext2 file system support in my kernel.
The filesystem was made using 'mke2fs'.... courtesy of my constant companion book from Karim Yaghmour.

Thanks again for your help,
Luke

Here is my current kernel file system related setup... #
# File systems

CONFIG_AUTOFS4_FS=y
CONFIG_TMPFS=y
CONFIG_RAMFS=y
CONFIG_PROC_FS=y
CONFIG_DEVFS_FS=y
CONFIG_DEVFS_MOUNT=y
CONFIG_DEVPTS_FS=y
CONFIG_EXT2_FS=y

#
# Network File Systems
#
CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
CONFIG_ROOT_NFS=y
CONFIG_SUNRPC=y
CONFIG_LOCKD=y
CONFIG_LOCKD_V4=y

[U-Boot-Users] LOADB in u-boot

Hi all,

I am new to u-boot. I am porting u-boot to Blackfin processor. I am
facing problems while loading the file via kermit to the target. Its waiting infinitely in the function k_recv, probably becoz its not receiving the START_CHAR. When i try sending the file from hyperterminal, it aborts after some time. What is the script send_image under tools directory? Do i need to do anything with that?

Please help me.

regards
vidya

I don't think that hyperterminal is capable of sending in Kermit binary protocol. Why don't you use kermit?

Did you read tools/scripts/README? If yes, which part did you not understand?
