Dear Sir/Madam,
I am using DVSDK 2.00.00.22 for DM6467 platform (custom board using EVM reference design)
The board vendor said the board will work with DVSDK 2.00.00.22 and
they have tested already and using it.
Using the installation guide, I installed DVSDK 2.00.00.22 on my
workstation running Ubuntu 10.04.
I successfully got the uImage, dsplinkk.ko and cmemk.ko
I downloaded the uImage to the board using minicom ymodem, exported
the filesystem through NFS
The following is what all I did:
***************************************************************************************************************

Since this uImage did not take the NFS exported rootsf from host, I
flashed the uImage which I got from the board vendor
(same DVSDK 2.00.00.22) but I did not change the rootfs (on the HOST
PC NFS). It fortunately worked.
Then I did as follows:
