I think first you need to do is to erase NVRAM and see if it works fine after that.

thanks a lot for your fast reply,

before this i use parallel jtag & i already erase NVRAM & KERNAL, but that did not work for me,.

so i decided to go by USBJTAGNT.
when i detect shows below

detect
IDCODE 0535217F
Broadcom BCM5352
IMPCODE 00800904
EJTAG V1, V2.0
DMA supoorted
Unknown flash type!
Report these values http://www.usbjtag.com/vbforum 0000,0000

tap c
tap a ffffffff
after this TRAP ON shows, DEBUG ON not shows.

i select SPEED2, slow speed also not work.
I cant erase KERNAL & NVRAM by using usbjtagnt, because it is asking "DETECT THE FASH TYPE FIRST"

please let me know which files i have to load in order to flash this dd-wrt.v24_micro_generic.

Your router has issue with hardware. Getting the flash type will not program the flash properly. The data bus 4 (D4) is grounded. All data on that pin is "0".
