Very-very first steps

[creaktive]

Hi everyone!!!
I've got this one and this one. Now, how do I wire them together?
May I just connect the corresponding pins (power/BDM/reset)?
Sorry for my lameness

Hi everybody,

I am in Creaktive's situation, but I use ETU version and Witztronics OSBDM. I have connected everything like your schematic, however, when I start HIWAVE I have a problem and it is shown a windows with the message:

ERROR WHILE LOADING DIAGNOSTICS ALGORITHM TO TARGET SYSTEM.
THE CHIP MAY BE SECURED, OR THE DERIVATE SELECTED MAY BE WRONG

This is problem is due to it is necessary to erase the whole flash before programming and I think it is locked by a loaded project which does not let me delete it. I am not sure, but I would like to know if you (Creaktive) or another one in my case have had some problems about that.

My best regards.

Josehida,

Did you solve your problem of "Error Loading Diagnostic Algorithm to target"? I understand this is an old post, but I am experiencing this problem as well. I have three boards built up in parrallel one works two suffer from loading Diagnostic Algorithm. They are not identical boards but very similiar a few farads of difference and trace correction not identical. I did think my dbm and rst lines were a bit noisy, but have since cleaned up the lines.

regards,

Cy

Hi josehida,

I am not sure what your problem is, but I can clear up one thing.
You can always connect via the BDM and mass erase the device, there is no inbuilt protection against this.
The security system is like this: you either know the code and can get in and do what you like or you can connect and bulk erase and start again. It is NOT to prevent accidental erasure from a BDM adapter. The block protection is to protect against accidental erasure and programming from within the device. It offers no protection from a bulk erase initiated from a connected BDM adapter.

Hello and welcome to the fora, creaktive.

Yes, this is what you would do.
Be sure to set the BDM adapter to supply 3.3V and not 5 volts.
That's it, the fun has just begun!

[creaktive]

Thank you, peg!
Well, these are the pins of my interest on PAN4555 module (the rest are I/O which I won't use right now):

1 GND Ground
9 GND Ground
11 BKGND Background
13 EXTAL Crystal oscillator input
14 CLKO Programmable Clock Output (default: 32,768 kHz)
17 GND Ground
24 Vcc Modem voltage regulators' input
25  GND Ground
26 Vcc Modem voltage regulators' input
27 RESET MCU reset. Active low
31 GND Ground

 I've also attached a bit from the reference circuit schematic which shows the BDM header connection.
As far as I understood, I should wire pins 13 & 14 together to use the internal clock. So far, so good
Now, can I wire the pin 25 to the :smileyminus: pole of a 3V lithium battery and the pin 26 to the :smileyplus: pole of the same battery? Should I also connect the pins 1, 9, 17 & 31 to :smileyminus: and 24 to :smileyplus:, or are they implicitly interconnected?
Pins 11 & 27 seems to match the BDM circuit; but how about BDM's Vcc & ground? May I get them from the same 3V battery?
Sorry about asking such an obvious things; I just could not found any BDM/PAN4555 interface implementation which was easy enough for me to understand it entirely

By the way, here is another BDM interface implementation, from the Freescale MC13213 reference documents (PAN4555 is just an MC13213 which can be handled... manually ). Here the resistor is 47k instead of 10k. The capacitor won't make a difference if I supply the power using a battery, right?

[creaktive]

Are there any step-by-step HOWTOs/tutorials for the Freescale stuff, just like for PICs? I just can't find it myself

[Witztronics]

What kind of tutorial are you looking for?

There is a quick start guide in the Codewarrior directory and example projects in the " Codewarrior_examples" directory.

[Witztronics]

I haven't used the Panasonic modules myself, but since they are based on a 9S08 micro, connecting the debug pins should be the same:

Pin 1 - debug
Pin 2 - GND
Pin 4 - reset
Pin 6 - VCC

Make sure you put JP1 in the correct position before connecting the WTBDMS08 debugger.  The WTBDMS08 can supply 3.3V or 5.0V to the target board if the current requirement is less than 100mA.  You can also set the target board (panasonic module) to supply the power if greater than 100mA or a voltage other than 3.3V or 5.0V.

[creaktive]

Wow! You mean, I do not need an "external" reset switch, neither a power supply; they already are implemented by the WTBDMS08 itself?! Sounds great!
I've already got some software projects for my module; my real problem is the hardware itself; remembering my last attempts with PIC (it was 6 years ago) sends shivers down my spine... Glad to see the tech evolving so fast!

[peg]

Well the tech evolution here is mostly the USB interface on the computer.
You get a free 5 volt supply included here. The BDM adapter just has a normal regulator on this to supply 3.3volts. There is a jumper to select whether the BDM cable is fed from the 5v straight from the USB port or from the regulator. In your case here you need 3.3volts selected. Refer to the schematic available on the Witztronics site.

[creaktive]

LOL, I'm a bit familiar with that archaic parallel port interfaces, and all I can say is that they suck a lot
Now, after connecting all the BDM pins, the only thing I need to do is to connect the clock input & output pins, right?

[Witztronics]

The WTBDMS08 does not supply a clock to the target board.

The target needs to have it's own clock source (most modules do).

[peg]

I believe the OP is refering to pins on the PAN4555 module here.

[creaktive]

LOL, one year later... Still fighting against this one

Actually, I was able to wire everything up to a state on the attached diagram. Then I launch hiwave.exe, go to Component=> Set Connection => HCS08 => HCS08 Open Source BDM, and then USB ACT LED blinks on my BDM and the Command window displays the following:

Hi!

Could you wire all the stuff together?

Could you finish your project with PAN4555?

I'm doing the same than u and have the same doubts like you.

Do you have your stuff about this anymore? Would you may send me your schematic and maybe a primitive code?

thank u very much!

yours sincerely,

daniel

I've 5 of this PAN4555 chips and i only want to communicate two of them. For example pressing a button on the first and turn a led on the second chip.

[Witztronics]

I am not familiar with this device, but it sounds like the chip is not running.

check your clocking, since the bdm does not supply a clock.

Also, that chip has more than one gnd and vcc.  Since you don't show them connected, are you connecting them?
