help:The following is a detailed description of the problems. I modified some parameters of the drivers/mtd/maps/rpxlite.c

This is NOT a U-Boot file.

and my mainboard the volumn of flash is :16M; but after compiling the kernel, which can't run ?the wrong message is following: ## Transferring control to Linux (at address 00000000) ...

This is NOT a U-Boot problem.

Kernel command line: console=ttyS0,9600 root=/dev/nfs rw nfsroot=172.16.115.2:/workspace/myfilesystem/target ip=172.16.115.7:172.16.115.2:172.16.115.254:255.255.255.0::eth0:off panic=1

...

Kernel panic: Failed to create the TCP control socket. <0>Rebooting in 1 seconds..

Looks like your kernel is misconfigured (no support for IP auto-configuration and/or root filesystem over NFS?).

But this has nothing to do with U-Boot.

another question is : static struct mtd_partition partition_info[]={ { name: "UBOOT", offset: 0, size: BOOT_PARTITION_SIZE_KiB*1024 }, { name: "JFFS2", offset: BOOT_PARTITION_SIZE_KiB*1024, size: (APP_PARTITION_SIZE_KiB)*1024 }, { name: "KERNEL", offset: (BOOT_PARTITION_SIZE_KiB+APP_PARTITION_SIZE_KiB)*1024 } }; I plan to modify like this ,which is ok?static struct mtd_partition fs_partition_info[]={} this struct is needed?

Yes, it is needed if you use static partition map.

But this has NOTHING to do with U-Boot.

Please don't post questions that are off-topic.
