Start by adding your BCM into your Vender xml

<Part>
<Name>BCM3368</Name>
<Id>0x3368</Id>
</Part>

Then we can start on finding the true values of the flash. Also what state is this device in ? is it bricked ?

You should be seeing values like 00c2 22c9 for example for this specific flash mx29lv640dbtc

As this is a residential gateway , you may find it has 2 BCM's inside ..

Try changing the configuration to a different one , What setting did you have it on, on the old usbjtag was it sbg900 as well ?? as that seemed to find the correct flash jedec ID

Flash xml for this chip would be

<flash>
<id1>0xC2</id1>
<id2>0x22CB</id2>
<name>MX29LV640</name>
<size>0x800000</size>
<protocol>0</protocol>
<block>
<secnum>128</secnum>
<secsize>0x10000</secsize>
</block>
</flash>

If it had the correct 00c2,22cb values

YOu have selected Target: SBG900 which I am not sure if it is right or not.
Try these command

flshdct 9fc00000
flshdct 9f800000
flshdct 9f400000

Also use "cfi 0" to disable cfi to see if you can detect it.

I would like to use logmein to take a look. If you can install logmein and go to chat at night I can take a look. Should be just xml fix. The target selection is the key.

Did you remove the bcm3368 from your vendor.xml ??
How many broadcom chips do you see on the device ?? and what are they ??
Have you tried selecting different targets ????????? << I ask this because you said you had correct values on old usbjtag.

Post up some high-res pics of your device as well , you may not be connected to the true jtag port .

Could you possably post just a picture of the board on here , as it looks similar to the webstar layout with the 8 pin jtag ( i assume you have buzzed the pins out)

there are 2 Broadcom chips on the board , could you identify both of there BCM names ?

the chips are:

bcm 3361kpbg and bcm5325ekqm6

I think the problem is the target model

i make other video

What target models have you tried so far ? Try some of the target models in the "router" section , i just want to see if you get the same values all the time .
