That seems to be a cable for Elite : I did the same....

 

[terzic]

empiezo a Ubuntu como el primer correo (danilp) todo está bien hacer:
openocd-0.4.0.tar.bz2 tar xjvf
no lo encuentra
de lo contrario (video evolutions) que inicie Windows comand mensaje no puede encontrar openocd \ 0.4.0 \ bin. no hay ninguna carpeta bin que he descargado desde el enlace anterior
¿Existe una solución?


I start ubuntu as the first mail (danilp) all OK to do:
openocd-0.4.0.tar.bz2 tar xjvf
can not find it
otherwise (evolution video) I start Windows comand prompt can not find openocd \ 0.4.0 \ bin. there is no bin folder that I downloaded from above link
is there a solution?

[pe.tardo]

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

A ver si te ha dicho que de qué "wataje" (que viene de "watt", watio-potencia) las querías
Dile que las quieres de 1/4 W (de un cuarto de watio), que son las redonditas con colorines

lo mismo el vendedor se ha pensado que eran para un electrodoméstico y te las quería dar de las grandotas

 

[Doume]

Whaoo ! The list of pins to connect on cable is different : Where did you find this one ?
I've nothing on Jtag pin 11 , for now... Missing in others schemes ?


About your problem : You badly read the doc :

You've to download openocd archive :
wget http://.....

And AFTER :
tar xvf

With this cabling, the cable does'nt work : It's like no cable was connected
But I'm practically sure the solution is there : On all others receivers, the Jtag requires 6 wires connected to parallel port
Probably the initial document was wrong, but this one too
Who can give us the good wiring ?

Below is the Parallel port DB25 pinout :

I took over the archives openocd ubuntu terminal (wget c * ttp: / / download.berlios.de/openocd-0.4.0tar.bz2) and manually from the link but do not see him again?
Duma, where dovnload tar xjvf ?
if anyone else has the same problem with openocd?
pe.tardo,
I have 1 /2 watt resistors

Me hice cargo de los archivos openocd ubuntu terminal (wget c * ttp: / / download.berlios.de/openocd-0.4.0tar.bz2) y de forma manual desde el enlace pero no lo volvería a ver?

I made ​​a mistake in the top post.soory

I have a problem with the opening of this forum, very slow to open
Tengo un problema con la apertura de este foro, muy lento para abrir

 

[Doume]

This forum has nothing to see with Azbox : The target JTAG is totally different (20 pins)

@Terzic :
I think you don't apply the documentation correctly
The wget command is to retrieve the archive on net

LATER, you'll use tar to uncompress it....

It's 2 different steps

 

[Doume]

I find the schema below, about Mips STB Jtag

Considering that, and if we consider the circuit 74HC244 is already on the board, the cabling should be :

DB25 Dir. JTAG

2 (D0) => 11 (RST_N)
3 (D1) => 7 (TMS)
4 (D2) => 9 (TCK)
5 (D3) => 3 (TDI)
6 (D4) => 1 (TRST_N)
11 (Busy) <= 5 (TDO)
20-25 (ground) 2 (ground)

May be TDO is not needed ?

But it's a lot different than the cabling proposed by document !

I'm becoming crazy.....

 

[arci]

Must respect I/O line definition in IEEE 1149-1 standard ...

to ALL ... For good results ... It's possible to confront with FC_Candido guide's (see: RP1-RP2 on Premium/+ ... or ... RP5-RP6 on Elite m-board) for correct Jtag lines daisy-chained conditions (pull-up +3.3 vdc for TDI-TD0-TMS-NTRST, or adaptive impedence conditions --- see TCK and TD0) and for install additional protective 100 Ohms series resistors (to limit the max current from the Jtag I/O lines)!

Here more info ... h**p://www.interfacebus.com/Design_Connector_JTAG_Bus.html ... extract:

TCK: [Test Clock] has noting to do with the board or system clock. The Test Clock is used to load the test mode data from the TMS pin, and the test data on the TDI pin [on the rising edge]. On the falling edge test clock outputs the test data on the TDO pin. As with any clock pin this line needs to be terminated in order to reduce reflections. The termination should be a 68 ohm resistor in series with a 100pF capacitor to ground. The TCK signal is bused to all Integrated Circuits [IC] in the JTAG chain. The signal may require buffering or be fanned out by multiple drivers depending on the distance and number of devices in the chain. Using multiple drivers would also require a termination resistor on each TCK line.

TMS: [Test Mode Select Input] controls the operation of the test logic, by receiving the incoming data]. The value at the input on the rising edge of the clock controls the movement through the states of the TAP controller. The TMS line has an internal pull-up, so the input is high with no input. The TMS signal is bused to all ICs in the JTAG chain. The TMS line should have a 10k pull-up resistor on the line.

TDI: [Test Data Input] receives serial input data which is either feed to the test data registers or instruction register, but depends on the state of the TAP controller. The TDI line has an internal pull-up, so the input is high with no input. The TDI signal is feed to the TDI pin of the first IC in the JTAG chain. The TDO signal from that IC is then sent to the TDI pin of the next IC in the chain or sent back out to the JTAG header. The TDI line should have a 10k pull-up resistor on the line.

TDO: [Test Data Output] outputs serial data which comes from either the test data registers or instruction register, but depends on the state of the TAP controller. Data applies to the TDI pin will appear at the TDO pin but may be shifted of a number of clock cycles, depending on the length of the internal register. The TDO pin is high-Impedance. The TDO signal is the output from a JTAG device that feed the TDI input of another JTAG device. The TDO line should have a 10k pull-up resistor on the line. The TDO signal should also include a 22 ohm series resistor placed near the last device in the JTAG chain.

TRST: [Test Rest] will asynchronously reset the JTAG test logic. The logic is reset (with TRST) regardless of the state of TMS or TCLK. The TRST signal is bused to all ICs in the JTAG chain. The TRST signal should include a pull-down resistor when possible to reduce the chance the signal floats.

P.S. With not-buffered Jtag-interface the wired lines must to be short ... and don't forget to enable the Jtag with jumper R309 (for Premium/+) or with JP2 (for Elite) ... How indicate on FC_Candido Guide's !

This is the correct pin layout of Jtag (MIPS EJTAG) on AZBOX m-board (for all series) !

Saluti ...

i have problem with google translate ( spanish to english), line tar xjvf openocd..... translate to openocd.....
now i have screen in ubuntu terminal like doumo:

@Arci

Thank you very much for these precisions,

But you did'nt describe the wiring between DB25 & Jtag connector on Elite
Many different approaches are proposed in this topic, but no one works for me
RP5 & RP6 seems to be equipped with resistors, on Elite

It's really not clear for me....

A good schéma, specific to Elite, would be very nice !

 

[terzic]

parport to EPP-corect ?

Is this important:
onboard parport - 378H/IRQ7 or 278H/IRQ5 ?

 

[terzic]

This I am clearly and that I work in ubuntu
sudo -i
mkdir azbox
cd azbox
sudo apt-get install libftdi-dev libftdi1 libusb-dev
wget -c http://download.berlios.de/openocd/openocd-0.4.0.tar.bz2
wget -c http://download.pristavka.de/azboxhd/az3_nor_flash.rar sudo apt-get install rar unrar
tar xjvf openocd-0.4.0.tar.bz2
unrar x az3_nor_flash.rar
cd openocd-0.4.0/
./configure --enable-dummy --enable-parport --enable-doxygen-pdf --enable-amtjtagaccel --enable-verbose --enable-ioutil --enable-zy100 --enable-x300t
make
sudo make install
sudo ln -sf /usr/local/bin/openocd /usr/bin/openocd
cd ..
Bien, ahora nos vamos a descargar y descomprimir el fichero Booting.zip que es el que contiene el programa para grabar el micro y el fichero que hay que programar,etc ...
wget -c http://download.pristavka.de/azboxhd/Booting.zip
unzip Booting.zip

It is not clear to me, how you overwrite, way ?
-Sobreescribir si es necesario ya que en este fichero están también los azbox.cfg y smp8634.cfg...
-Copiar los ficheros que hemos descomprimido del booting.zip a los directorios como se ve abajo sobreescribiendo los existentes :
-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[/b]

 

[Doume]

The good comands are :

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

 

[terzic]

O KET, I try.

 

[terzic]

378H/IRQ7 or 278H/IRQ5 ?

 

[terzic]

I tried again and all done by the end except the command:
sudo cp az3.bin/usr/local/share/openocd/scripts
but
cp: missing destination file operand after `az3.bin/usr/local/share/openocd/scripts
the other two command last until the end
When I conected with azbox and launched a last-f command interface ......
