Zhang, Unfortunately, I have no experience with the MVL 5.0 release and cannot offer any assistance on the matter. I'm sure there were significant changes to the kernel, drivers, etc. between the two releases, but I wouldn't be able to tell you what could be causing the different behaviors you are seeing. I would recommend contacting MontaVista to see if they could detail the changes between the releases.

I am use the LargePage Nand Flash (ST's NAND01GR3B2B NAND Flash ) on my DM6446 EVM, When I use the MVL4.0 kernel on my board, I found that the kernel would scan all the blocks of the whole nand flash as bad blocks. However, When I use the MVL 5.0 Kernel on my board, the kernel would find no bad blocks of the whole nand flash. So I want to know how to update the MTD drivers for the nand flash from MVL 4.0 to MVL 5.0? could you give me some advies about that situation? 2. If the above problem would not be sovled correctly, I have to change my kernel from MVL 4.0 to MVL 5.0. While I found that the MVL 5.0 kernel could not mount the NFS correctly, the kernel would halt mounting the NFS for ever, the following is the messages: ======================= IP-Config: Complete: device=eth0, addr=192.168.0.125, mask=255.255.255.0, gw=192.168.0.1, host=XJTUIPCEVM, domain=, nis-domain=(none), bootserver=192.168.0.238, rootserver=192.168.0.238, rootpath= Looking up port of RPC 100003/2 on 192.168.0.238 portmap: server 192.168.0.238 not responding, timed out Root-NFS: Unable to get nfsd port number from server, using default Looking up port of RPC 100005/1 on 192.168.0.238 ======================== But When I use the MVL 4.0 kernel, I found that the kernel woud correctly mount the NFS with no errors. Between the two situations my u-boot ENV is the same configurations: bootargs=mem=120M console=ttyS0,115200n8 root=/dev/nfs noinitrd rw ip=192.168.0.125:192.168.0.238:192.168.0.1:255.255.255.0:XJTUIPCEVM nfsroot=192.168.0.238:/home/workdir/rootfs,nolock video=dm64xxfb:output=pal So I want to know whether there are some necessary differences about the kernel configurations between the MVL 4.0 and MVL 5.0 or not. Such as "make menuconfig", "u-boot env setting (bootargs, etc.)" Thand you, Hope for your reply. Zhang
