Hi Champions,
I want to use the ramfs instead of NFS for MCSDK-HPC, the following is my test procedure, but it doesn't work, could you please give some comments?
Installed packages: MCSDK_3_00_04_17, mcsdk-hpc_03_00_00_18
1. Unpack TI SDK Root File System, the file tisdk-rootfs.tar.gz is from /mcsdk_linux_3_00_04_17/images folder
2. boot the K2H EVM via NFS
3. Install the HPC IPKs to update EVM filesystem with SDK binaries
4. use the following commands to compress and Zip the filesystem
cd /evmk2h_nfs
sudo chmod -R 777 *
sudo find . | sudo cpio –H newc –o –O new.cpio
sudo gzip new.cpio
sudo cp new.cpio.gz /tftpboot
5. Modified the u-boot environment to boot from ramfs.
When the kernel start up, it reported the kernel panic:
VFS: Cannot open root device "ram0" or unknow-block(0,0):error
Please append a correct "root=" boot option; here are the available partitions:
1f00 1024 mtdblock0
1f01 512 mtdblock1
1f02 522752 mtdblock2
1f04 15872
Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(0,0)
And I also tried to modify the args_ramfs parameters root=/dev/1f00, it can't work. It seems the MCSDK3_00_04_17 can't support ramfs.
Zhan.
