Hi, We added function flash_unlock in the the u-boot-1.1.4\board\davinci\flash.c file and called from flash_init(). Which helps us to write NOR flash using cp.b . If we unlock from U-Boot then JFFS2 image can be written using cp.b command. This helped us to load the Jffs2 file system so that we won't get read only file system error.

But before that please make sure that you have modified ~/dvsdk_1_30_00_23/Rules.mk file to match your environment. If the ~/dvsdk_1_30_00_23/Rules.mk file is correctly matching your environment, the "make" command should be able to build demo apps (encode and decode) for you by compiling various files.

The result is a folder called 'dvsdk' into my environment. Then, I have followed instructions from 'encode.txt'.
