TUTORIAL Recuperar deco en "Booting" via JTAG

[danilp]

Tampoco funciona en mi caso (Premium HD), he verificado con un multimetro las resistencias y el pineado, la unica cosa que he notado es algo que sale al intentar el antepenultimo comando, lo cual veran en la captura de pantalla que subi, esperemos conseguir la solucion para que sea beneficioso para todo aquel al que le pase lo mismo ​

Lo que pasa es que la pantalla de la izquierda que es la que conecta con el azbox te está dando problemas, por eso los comandos que metas por la derecha (telnet) no te van a funcionar...

Te has bajado el booting.zip y lo has descomprimido y copiado los ficheros en su lugar correspondiente machacando los que ya había?
Posteo original:

copie o arquivo azbox.cfg para /usr/local/share/openocd/scripts/board
E o smp8634.cfg para /usr/local/share/openocd/scripts/target substituindo o
original.

Nota: o azbox.cfg e smp8634.cfg contém as modificações que fiz para o programa
openocd identificar a bios do azbox e sendo assim conseguir reprogramá-la não
alterem e nem modifique o conteúdo destes 2 aquivos.

Has puesto el puerto paralelo en la bios en ECP/EPP ¿?

Saludos!

In the documentation, about software, I read that :

cd ..
sudo cp az3.bin /usr/local/share/openocd/scripts
sudo cp smp8634.cfg /usr/local/share/openocd/scripts/target/smp8634.cfg
sudo cp azbox.cfg /usr/local/share/openocd/scripts/board/azbox.cfg

OK for az3.bin : it's into the current directory
But smp8634.cfg seems to be located there : openocd-0.4.0/tcl/target/smp8634.cfg

and I did'nt found any azbox.cfg ??????

Any tips ?

 

[danilp]

We are talking about may be you need to download the file booting.zip and decompress to get the modded files of smp8634 and azbox.cfg and the bin file to write on flash.
az3.bin on the manual i write is not needed because inside the booting.zip are the goos file i write on my flash...
Download booting.zip and copy the files overwriten the existing files...try.

Sorry for my english...

 

[Doume]

I've prepared the cable for Elite, and installed software as listed

Just a remark : the smp8634.cfg and azbox.cfg are included in file 'Booting.zip' , so you've to download this file and unzip it BEFORE to copy thoses files to /usr/local......
And their source PATH is ./Booting/smp8634.cfg
(Document needs a fix.... )

When I've started openocd, I obtain this result :

root@medion:/usr/local/share/openocd/scripts# openocd -f interface/parport_dlc5.cfg  -f board/azbox.cfg

[Doume]

Somebody could say, if something must be displayed during flash, into the screen running 'tjtag' ?

I'm still having as last message :

Is it normal ?

Has puesto el puerto paralelo en la bios en ECP/EPP ¿?

Saludos!

Si, Si, El puerto paralelo no iba en EPP??? Seria buenos screenshots como decian anteriormente de cuando funciona correctamente

 

[evox]

Como bien indica danilp el tutorial es para Premium+ y creo que el ultimo comando a enviar es distinto para los Elite y Premium, estos quedarian asi.

Premium+:

sudo ./tjtag -flash:cfe /fc:104 /bypass

Elite y Premium:

sudo ./tjtag -flash:cfe /fc:87 /bypass

Haber si con esto avanzamos.

Salu2.

 

[terzic]

now nothing unclear which scheme applies to the elite model?
is there anyone that has successfully solved this problem with the Elite model and how ?

ahora nada claro qué régimen se aplica al modelo de elite?
hay alguien que ha resuelto con éxito este problema con el modelo Elite y cómo ?
translate on google, soory !

Lo intente de nuevo hace un momento en ambos modos ECP/EPP y EPP, No se que rayos pasa :blink: :blink: :blink:

 

[Doume]

Muchos gracias

With those videos, it's clear : The 1st step through telnet should work correctly, not like in my previous post

I'll recheck everything, and go further

Thanks for all

 

[terzic]

cualquier persona que lo ha conseguido con un modelo que queremos aclarar el esquema de conexión y el proceso?
gracias

anyone that has managed this with the "elite" model that we clarify the connection scheme and the process?

thanks

 

[Doume]

It seems openocd is'nt working, on my Linux PC
On video, he uses Windows to run openocd and telnet session ? I'm really confused....

 

[Doume]

I've checked parallel port in BIOS : Sure it's in EPP mode
I've checked the cable between DB25 and JTAG connector on Elite : All is OK

But when I run openocd and telnet session, nothing works like in video

I suspect the config files provided in packages are'nt OK for an Elite model

And when running tjtag, the following is different from video :

- EJTAG IMPCODE ....... : 11111111111111111111111111111110 (FFFFFFFE)
- EJTAG Version ....... : Unknown (7 is a reserved value)

Something is probably wrong into cable, or Linux driver.....



Google translation :
He comprobado el puerto paralelo en el BIOS: Claro que es en el modo EPP
He comprobado el cable entre DB25 JTAG y en Elite: todo está bien

Pero cuando corro sesión openocd y telnet, nada funciona como en el video

Sospecho que los archivos de configuración se entregan en paquetes are'nt bien para un modelo de Elite

 

[Doume]

To be sure, I made a try of OpenOCD using Windows XP, like on demo video

The result is a bit different than Ubuntu, when starting openOCD, but that does'nt work, too :

Por cierto, he hecho un intento de OpenOCD utilizando Windows XP, al igual que en el vídeo de demostración

El resultado es un poco diferente de Ubuntu, al iniciar openOCD, pero que me cansaría de trabajo, también:

Mi conclusión por ahora: el procedimiento, o del cableado, no se pueden usar con Elite

 

[danilp]

Aseguraros de sobreescribir los ficheros co los de booting.zip.... alguien que lo pruebe en premium+¿?

Si mi pana, los sobreescribo en sus carpetas correspondientes smp8634.cfg en /usr/local/share/openocd/scripts/target/ y azbox.cfg en /usr/local/share/openocd/scripts/board/ aparentemente hay que adaptarlo a nuestros decos, mmm voy a ver si busco un tecnico en electronica para soldarle el par de resistencias SMD 103 = 10000 Mega Onmios y intentarlo segun el tuto brasileño, mas bien no se como pude soldar en RPG 1 y 2 :lol: :lol: :lol:

 

[Doume]

I've tested an another PC, to be sure the parallel port was'nt the source of problem : Same result !

I think the following message :

Error: Error writing unexpected address 0xfffffffe

signifies something is wrong into cabling or clocking on interface : Datas are strobed to "FFFFF" (all "1" ) , instead valid addresses

 

[Clemente]

esta mañana he ido a comprar todos los componentes y a la hora de comr las 8 resisitencias de 120 ohmios me dice el voltaje con que las quiero, ya que hay de varios voltajes , me gustaria que me dijerais cual tiene que ser y por lo que estoy leyendo ese puede ser uno de los problemas, muchas gracias y salu2
