azbox elite

Post by happyhammer »

this is a sister product of the azbox premium that was debricked in another thread. it uses same CPU,same flash. same firmware.
The Premium has previously been debricked using a parallel jtag and openocd/tjtag combination but the elite vesion could never get debricked using this combo. The reason is unknown, hence i am trying with usbjtagnt.

The elite has the JTAG 14-pin header populated on the board already. I have the Jtag enable pin shorted to 3.3v

using usbjtagnt on the elite i get this

IDCODE 08630001
ADM Part NotFound 8630
IMPCODE FFFFFFFE
EJTAG V3.1
DMA not supoorted


on one occasiuon i got this

Copyright (C) 2010,2011,2012
USB JTAG NT 0.54
Target: AzboxPremium
-tap c
Eco :FFFFFFFF
-tap a ffffffff
Eco :FFFFFFFF
-detect
IDCODE 08630001
ADM Part NotFound 8630
IMPCODE FFFFFFFE
EJTAG V3.1
DMA not supoorted
Unknown flash type!

i believe on a premium model i would get something like this
Copyright (C) 2010,2011,2012
USB JTAG NT 0.54
Target: AzboxPremium
-detect
IDCODE 08630001
ADM Part NotFound 8630
IMPCODE 40414000
EJTAG V2.6
DMA not supoorted
Found Address= 8c000000 Compatible flash CFI AMD064


I know usbbdm is not back till 19th Nov but has anyone any suggestions what could be wrong?

If you Know the Flash Model Number then One can look Up the PDF for it and make the necessary Addition in the Flash XML and create an XML specific For that Target.

@Capone. Thx for responding.

the flash chip is the same on the elite model as on the premium model, that is, its a "nor flash EON: EN29LV6408-90TIP"

That flash is detected by usbtagnt when connected to a Premium model with the Target set to Azbox premium and no changes to the flash.xml file.

So perhaps something else needed when working with the elite model.
Note: When trying the parallel jtag/openocd method with the elite, the cpu was never put into "halt" state in the sequence below, so reset,reset init and all the other commands failed as target was not halted. Maybe that is related to why usbjtagnt is not presently working with elite model.


Open On-Chip Debugger
>halt
>reset
>reset init
>flash protect 0 0 last off
>flash protect_check 0
>flash info 0
>shutdown
-3 Flash is ready to use the now unprotected tjtag to flash the bios.
sudo ./tjtag -flash:cfe /fc:104 /bypass

This Info is Not of Much Help. SO if you can ID with azbox premium Whats the Problem. What Info you get on screen.

when i hit detect from within the usbjtagnt program, i get this only:

IDCODE 08630001
ADM Part NotFound 8630
IMPCODE FFFFFFFE
EJTAG V3.1
DMA not supoorted

that is all, it has not detected the flash so read chip etc dont work.
i assume the IMPCODE is wrong?



on one occasion . when trying some tap commands before the detect command, i got this

Copyright (C) 2010,2011,2012
USB JTAG NT 0.54
Target: AzboxPremium
-tap c
Eco :FFFFFFFF
-tap a ffffffff
Eco :FFFFFFFF
-detect
IDCODE 08630001
ADM Part NotFound 8630
IMPCODE FFFFFFFE
EJTAG V3.1
DMA not supoorted
Unknown flash type!

Is there a "jtag enable" jumper on the board?

Try slower JTAG speed. ("speed 2). And see if you get IMPCODE correct.

sorry for slow response, i'm on GMT so time lag is a problem.


@merkin. yes there is jtag enable pin, this has been connected to 3.3v. if its not enabled you dont get IDCODE 08630001.

@usbbdm. tried speed 2 but result is the same

Have you read this?

Yes. I have read this and this is why I buy usbjtagnt since it seemed to work quite easily with the premium so I was hoping it was flexible on how it picked up the jtag interface. I guess there is something amiss with the jtag even though it has the 14 pin header populated.

It looks to Me Like the CPU may be the Same But not the Flash, If so the Flash would need to be Added to the Flash.XML.

Somthing is Different for sure. If It where Exactly the same then It should Detect Properly and be able to read and Write.

Other than that It can also be a Connection Problem. Since on Occasion you Get a Different Result.

He mentioned that he need to do something to enable JTAG. I see the TDI pin is not enabled. That is why it will not work.
