USBJTAG NT New xml Dump

 

[D3m0n]

Right firmware and bootloader images all size up as correct. There are differances on the CFG and LOG files with BC ( I will rectify this ). I noticed when a full dump is extracted with BC it goes exactly as per the Flash Show list , however NT has started at the Bootloader ? (I will enquire about this).

As you have a working backup , could you try run a write test on BC doing only Bootloader , Firmware and Firmware X , and then Full Dump dont try on CFG or LOG as they will fail.

Latest BC USB 8 MB dump and files

Latest Script file

 

[D3m0n]

Seems to be corresponding more with your dump from NT now , i can only see visable changes in the log which is to be expected.

Just need a write test now to see

 

[TinyOne]

GREAT !!!!

 

[D3m0n]

Can you verify for me if your boot, firm , firmx ,cfg and logs write back as well as a full flash write.

Many thx

Firmwarex didnt work right

It called it ok

but it wrote it in les sthen 1 sec

Testing

I guess the Script needs work on writeing..

It read fine

It writes some stuff good

and some stuff not

I wasn't getting any errors

until I tried to Write the whole Flash..

and Firmwarex

I don't know if the errors mean anything...

The LEDS are Flashing on the CG

I think it needs some cmd to stop the Watchdog

For the Whole Flash write

Firmwarex tab reads fine

Writes wrong...
It doesnt get a error but its done immediately..

The other Tabs Read and Write OK..

This is a Virgin CCR

Do you want me to try writing HAX on it???

 

[D3m0n]

I will work on the script , need to talk to the developer regarding the watchdog . I am sure Hax will fail if you dont get a good write normally on FirmX.
