[U-Boot] Regarding HUSH support in uboot

[amruth vamadev]

Hi
How do we know whether hush shell capability is supported or not in
the command shell.I have enabled CONFIG_SYS_HUSH_PARSER in in config
file.
I am trying to write simple script like below
myname=`test`
if $myname=test
 then echo "test"
else echo "failed"
fi
I am getting the following error "unknown command test".
Can anybody please let me know if the hush shell is eanbled or not.
Thanks
