recent i do flash for my a-dsl router
Sagme 2404
frimware :- openwrt-F@ST2404-jffs2-64k-cfe.bin   
after i do upgrade through web interface
route stick with on led on
so i have dku-5 cable
i make my serial cable and work fine
via serial cable i get kernel painc  so
i hit space bar and get inside CFE cli
all this good till now
so i am using command
flashimage 192.168.1.1:cfe.bin
cfe.bin is same frimware  i download from openwrt download site
some thing i can't understand is
why give error
Loading 192.168.1.100:cfe.bin ...
Loading failed.: CFE error -4
*** command status = -4
and in server tftp log said client terminate connection
So now i need to build jtag cable
if yes
my second question is
jtag port in this pcb under pcb
because i found 12 pin's
and till now i have no idea about it

some tftp clients seem to have troubles with images of more than 4 MB size. maybe you can transfer the image over the serial link.

Thank you for respond to me
i solved the problem router work fine now
