Try pin 2 of the 14 pin chip PS54325 (or pin 7 of the chip). Please do not do hot plug or you might kill JTAG NT.

I do not want to burn my jtag ..someone with experience at the modem

You can use a resistor connect pin 2 of the chip to 3.3v on the board. This will not kill your JTAG NT. Only hot plug will likely to kill your JTAG NT.

If you get the flash ID detected then you can consider connect it to pin 1 of NT.

everything is like the SBG6580 different is the ISP ??

it is PUMA5, but 64mb I think so.
here is the memory map

actually is 128MB, more can be summed up in 16 MB, for a perfect copy of Flash, flash in the two copies attachments with XML posted by our "usbbdm"!! if someone can post the split sectors XML please!

You said the flash is 128M but two files are only 32M combined.

[FoxHazard]

yes, the id of the flash is

Found Address = 00000000 25L128
flshdct-0
Found Address = 00000000 25L128

That means it is 16MB and 128Mb (b is bit and MB is Byte).

[softrend]

nvram is not within the 16mb, I have a full dump, but do not have nvram ... so, not have certs.
