Hi Quentin,
I can see that NFS support is enabled in default PHYTEC 3250 configuration in LTIB GUI:
1. Execute ./ltib -c to get the LTIB configuration
2. Enable the "Configure the Kernel" option in GUI. This will provide the Kernel configuration GUI before it builds the kernel.
3. In Kernel configuration GUI, you can see " File Systems->NFS", enable the NFS options which are required
You can find the the kernel configuration file created by LTIB in /ltib/config/platform/phy3250/linux-2.6.34-phy3250.config.
Regards,
Giri

Subject: Re: [Ltib] Phytec LPC32xx Board Failed to mount RFS after using Kernel 2.6.34 ?
Hi Giri,
Thanks for asking me about my Phytec Board Adventure.
As recommended by Srinivas, I've been trying to get 2.6.34 running on Phytec board.
Still not winning yet.
I am using LTIB tool to build the kernel. (Did not try using make command.)
One thing I learned was 'I have to use Tool Chain -- "tc-fsl-x86lnx-armeabi-nptl-4.1.2-3.i386.rpm" in PATH "/opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi".
I failed kernel build after error message "cc1: error: invalid option `abi=aapcs-linux' " when using Tool Chain -- "tc-nxp-lnx-arm-3.4.5-1.i386.rpm" in PATH "/opt/nxp/gcc-3.4.5-glibc-2.3.6/arm-linux-gnu"
( After googling error "cc1: error: invalid option `abi=aapcs-linux'", it looks I have to disable 'eabi support' when using Tool Chain -- "tc-nxp-lnx-arm-3.4.5-1.i386.rpm". which I did not do further test. )
Anyway, I successfully compiled 2.6.34 kernel for Phytec board using Tool Chain -- "tc-fsl-x86lnx-armeabi-nptl-4.1.2-3.i386.rpm".
But for some reasons, which I am trying to find out, Phytec board could not mount rootfs.
I ATTACHED THE PHYTEC BOARD SERIAL PRINT FOR YOUR REFERENCE.
I could not see following lines in kernel .config of 2.6.34, which is my main worry now.
CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
# CONFIG_NFS_V3_ACL is not set
# CONFIG_NFS_V4 is not set
CONFIG_ROOT_NFS=y
# CONFIG_NFSD is not set
CONFIG_LOCKD=y
CONFIG_LOCKD_V4=y
CONFIG_NFS_COMMON=y
CONFIG_SUNRPC=y
# CONFIG_RPCSEC_GSS_KRB5 is not set
# CONFIG_RPCSEC_GSS_SPKM3 is not set
I tried to get 'CONFIG_ROOT_NFS=y' in LTIB kernel config GUI.
HELP SHOWS:
Symbol: ROOT_NFS [=n]
Prompt: Root file system on NFS
Defined at fs/nfs/Kconfig:86
Depends on: NETWORK_FILESYSTEMS [=y] && NFS_FS [=n]=y [=y] && IP_PNP [=y]
Location:
-> File systems
-> Network File Systems (NETWORK_FILESYSTEMS [=y])
-> NFS client support (NFS_FS [=n])
But in LTIB 2.6.34 Kernel config GUI, I only get this
--- Network File Systems
< > SMB file system support (OBSOLETE, please use CIFS)
< > Ceph distributed file system (EXPERIMENTAL)
< > CIFS support (advanced network filesystem, SMBFS successor)
< > NCP file system support (to mount NetWare volumes)
< > Coda file system support (advanced network fs)
< > Andrew File System support (AFS) (EXPERIMENTAL)
I am bit lost what to do now.
Don't know WHERE TO SET "CONFIG_ROOT_NFS" in LTIB GUI.
I manually added above lines in .config, but they were always removed after running './ltib'
Hope you can point me to the right direction.
Regards,
Quentin

Hi Quentin,
How are u building the kernel? Are uy trying to build the kernel alone by using make command (in kernel tree)?
If you are trying to build the kernel by using make command in kernel tree, please set the cross compilation tool chain path in PATH variable.

Giri

Subject: [Ltib] How to skip command-line question based kernel configuration when doing Kernel 2.6.34 configuration for Phytec LPC32xx board ?
Hi,
Regarding latest Linux Kernel configuration when chosing "Kernel_2.6.34" for Phytec board.
WHY LTIB is STILL ASKING THE KERNEL CONFIGURATION in COMMAND-LINE after I've finished all kernel configuratino in GUI?
Very time consuming to go through and answer each question.
Can anyone tell me how to skip these command-line questions AS SHOWN BELOW? Thanks a lot.
