Well, I tried to rebuild everything from scratch, still same problem
with busybox. SH is configured in BUSYBOX however:

CONFIG_USER_BUSYBOX_SHELL=y
# CONFIG_USER_BUSYBOX_ASH is not set
# CONFIG_USER_BUSYBOX_SH_IS_ASH is not set
# CONFIG_USER_BUSYBOX_HUSH is not set
# CONFIG_USER_BUSYBOX_SH_IS_HUSH is not set
# CONFIG_USER_BUSYBOX_LASH is not set

CONFIG_USER_BUSYBOX_MSH=y
CONFIG_USER_BUSYBOX_SH_IS_MSH=y
CONFIG_USER_BUSYBOX_COMMAND_EDITING=y
CONFIG_USER_BUSYBOX_COMMAND_SAVEHISTORY=y
CONFIG_USER_BUSYBOX_COMMAND_TAB_COMPLETION=y
CONFIG_USER_BUSYBOX_COMMAND_USERNAME_COMPLETION=y

Ah, ok.  I'll see about patching this into PetaLinux.  Spartan2 is 
ancient history but obviously a few people (like yourself) are still 
using it.

Yep - caches are really not optional for external memory, and uclinux in

particular.

After all the changes you've been making, I'd recommend a cmoplete "make

clean dep all" to rebuild everything - libs, apps, kernel, romfs, image,

everything.

The error you are seeing looks like a budybux build sycnh issue - just 
clean it all out and rebuild will probably fix it.

John
