IDCODE 80000000
Manufacturer not found 000
IMPCODE 80000000
DMA supoorted

This is what i get from a netgear modem/wireless router
I had to make a header adapter to get pin 1(i think) to get this reading if it is correct.Anything can be done with this???

I do not see the JTAG header is properly connected or if it even uses JTAG. Untill CPU ID is properly identified the flash type will not be recognized.

1 on main board is BCM3349KPBG
1 on wireless board is BCM4306KFBG

adrian, dont be so mean! it uses the same processor as a sb5101. i would expect the flash to probably be 8mb containing an operating system which is for both the modem and also the wireless portions. i would like to see a top view and bottom view of this board if its possible.

If you have two CPUs, you must have two flash chips and most likely you have two JTAG ports. This is what happened on DCT6412 which has one EJTAG64 and one EJTAG32 for cable modem.
