wrt54g v2

Post by jay209311 »

Hello all. I'm trying to Program whole flash of a wrt54g v2. Could some one tell me the address of the whole (4mb) flash? I try 9fc00000 and says check memory.

You cannot use WRT54GV6 configuration.
Either edit in the usbjtag.def or create a new section and tell it is 4M flash.

Memory=Ram,0,0x80000000,0x800000
Memory=CFE,1,0x9fc00000,0x40000
Memory=KERNEL,1,0x9fc40000,0x1B0000
Memory=NVRAM,1,0x9fDF0000,0x10000
Programram=0x80200000
Endian=Little
IRLength=8
Protocol=EJTAG
DMA=Yes
