Hi All ,
a/ I am able to load u-boot.noxip.bin [UBOOT] , uImage [KERNEL] & rd-jffs2.bin [JFFS file system] on NAND [Board is DM816x EVM]
b/ When i try to boot the EVM in NAND mode i am getting KERNEL PANIC message of
//Only last part of kernel panic , please let me know if the entire log is required

Please find below mentioned steps used to have EVM configured to boot from NAND :-
A) Loading the u-boot.noxip.bin (default available from prebuilts binary folder)
1. mw.b 0x81000000 0xFF 0x260000
2. tftp 0x81000000 u-boot.noxip.bin
3. nand erase 0x0 0x260000
4. nandecc hw 2
5. nand write.i 0x81000000 0x0 0x260000
6. nandecc hw 0
B) Loading the Kernel image (uImage)
1. tftp 0x81000000 uImage (Bytes transferred = 2566084 (2727c4 hex))
2. nand erase 0x00280000 0x00440000
3. nand write 0x81000000 0x00280000 0x272800 [ the size entered is made multiple of 0x800 to remove alignment error ]
C) Creating the JFFS file system
I could not find any default rd-jffs2.bin file in the /home/ashish/ti-ezsdk_dm816x-evm_5_05_02_00 directory.
Hence i tried below mentioned steps to create an JFFS file-system :-
a/ Under /home/ashish/ti-ezsdk_dm816x-evm_5_05_02_00/filesystem directory there was two tar available :-
arago-base-tisdk-image-dm816x-evm.tar.gz [ rd-jffs2.bin was around 14MB ]
ezsdk-dm816x-evm-rootfs.tar.gz [ rd-jffs2.bin was around approx 450MB ]
b/ Untar the arago-base-tisdk-image-dm816x-evm.tar.gz under /home/ashish/test.
Then created JFFS file system by :-
sudo mkfs.jffs2 -lqn –e 128 -r /home/ashish/test -o /tftpboot/rd-jffs2.bin
D) Loading the NANAD JFFS file system
a. mw.b 0x81000000 0xFF 0x0C820000
b. tftp 0x81000000 rd-jffs2.bin [ Bytes transferred = 14715080 (e088c8 hex) ]
c. nand erase clean 0x006C0000 0x0C820000
d. nand write 0x81000000 0x006C0000 0xe09000 [ the size entered is made multiple of 0x800 to remove alignment error ]
e. console=ttyO2,115200n8 root=/dev/mtdblock3 rw rootfstype=jffs2 mem=100M earlyprintk
setenv bootcmd 'nand read 0x81000000 0x00280000 0x272800;bootm 0x81000000' [ 0x272800 as mentioned in B.3]
ould you please help me to figure what mistake i am doing .
Thank You,
Ashish Kumar Mishra
