Thanks I got it.
I following guide :

Or if you use cfi flash, in kernel menuconfig,
Memory Technology Devices (MTD) -->
<*> Memory Technology Device (MTD) support
[*] MTD partitioning support
<*> Direct char device access to MTD devices
<*> Caching block device access to MTD devices
RAM/ROM/Flash chip drivers -->
[*] Detect flash chips by Common Flash Interface (CFI) probe
[*] Detect non-CFI AMD/JEDEC-compatible flash chips
[*] Support for AMD/Fujitsu flash chips
(3) Retry failed commands (erase/program)
Mapping drivers for chip access -->
[*] Maps for Altera Nios Development Kit
File systems -->
Miscellaneous filesystems -->
<*> Journalling Flash File System v2 (JFFS2) support
Then rebuild the kernel, and boot nios2 uclinux.
It should display jffs2 support and detect mtd partitions.

Then I rebuild zImage and use nios2-download -g zImage to download my DVB, I did not program the zImage to dvb flash.
When nios2-download is complete , display boot information:

Then I use mount cmd:
+++++++++++++++++++++++++++++++++++++++++++++++++++++# mount -t jffs2 /dev/mtdblock0 /mnt
Eep. No valid nodes for ino# 1#

I mount faile. Why? How can I solve it? Thanks a lot!
