Here is BDM 100 Update

[ipejasinovic]

No, Chinese BDM100 is actually clone of older CMD BDM flasher.

A dump for 68hc11 ?

many thanks

true
does anybody had some schematics of the probes used with it? the probe's pcb can be easily made, but i need the schematics for theme...

[racin-snake]

i just bought a bdm clone
theres apdf with the wiring in there
ile try to upload the pdf if ya aint got it
or maybe if ya got that i can take a pic of the pins and adaptors
try to work it from there?

Dude, look at previous page...

[rappttor]

mates, i had that pdf also, and many others, i have all 3 probes wich comes with the china clone, i know the bdm pinout, but i need the configuration of probes for different types of ecu...

for exemple wiki said that all the bosch ecus has the same pinout pad, and i had test it, it works, but for an simens ppd 1.5 for exemple? i know the pin 1, but the rest of the pins? and so one for the rest of the ecus: delphi, marelli, simens sid, simens etc
for each of theme there are probes, i need this ecus pinout pad configuration; diferent size and CONFIGURATIONS !!!!

hope that i had made my self clear enough.

regards

I build one but I need dump for 68HC11 can help me somebody?

[rappttor]

nobody????

First at all to we dissemble mystery about famous BDM100 background debagger for MCP555/6 serie of motorola MCU.
Many peoples think about " hove that little thing work ? " .

So simple and I was research it about 5 days but precise.
FTDI232 is simple but fast USB to RS232 converter ( nothing more then RX and TX ). All is in 68HC11E1. The target program is famous dump which must be inside (internal eeprom section of HC11E1) it size is standard 512 bytes.It is modified dump of old motorola BDM project.

How it work and why HC11 ?

HC11 have one beautiful option : "special bootstrap mode".
To put it in that mode you must set MODA and MODB to gnd.Immediately after power on HC11 the RX and TX pins must be short ! HC11 will recognize it own signal from TX pin on self RX and jump to location B600 on internal memory.
After that moment we must break our loop back link and make normal connection of RX and TX pin's ( a couple of mS).
And start to execute next 512 bytes.
And we wait him there HEHEHE there is our BDM100 debugger code ( our famous dump ... ).
The peoples who make that interface are include serial and other thing's for them need's.....
The main part is application on PC.
If HC11 after that trick not find that 512 bytes it will jump to bottom memory locations where is assembled BUFFALO program from Motorola company as default and execute him.....

At moment I work on last family Motorola debugger to translate it for our need's.
P.S. I never love motorola MCU-s but that BDM put me to reasrch that .......sh..t's

Here is screen shoot of memory dump ...
HC11E1 BDM100 B600.jpg

And for peoples who make it two thing :
1.Use only 74HC14 not LS14 ( se on scope why ).
2.Use only short cable from your BDM100 to ECU ( not longer then 20 cm max better short).

Sorry for my bad English ...

The best regard's Robert

hi,

how you explain BDM clone from china have 2 models
one model need power supply direct on ECU plug , and second model no need power supply ( is BDM give power to ECU )

That is only technical thing of constructor of PCB.
I have in my BDM separate power for relay from BDM power supply via 78L05 to remove chance for USB damage when relay is energized ( in that moment on relay can be induced very big voltage and maybe damage USB port).Also I have a couple clamp diodes and more modification my personal....

You have big difference inside clone maker.I am electronic engineer ( and have a lot of knowledge about what an how work and more... ) and you have peoples who just copy paste project's but never get how it work.

Did you sometime research some interface in all aspect ?
I like to make hardware for my usage and copy all that things
but always only get idea's and maybe software which is hard Analise ...

And from there your question come mate ...

End if you need to learn more about famous BDM for MPC MCU serie 55x and 80x here are help :

Macraigor systems pinouts.pdf

ManGDBPPC-3000.pdf

MCP LPT debuger datasheet.pdf

The answer's are all around as and we have wonderful
thing called INTERNET and we just need to find and learn.

None are born as GENIUS ! That is difference .....

Just noticed with the bdm when opened, pin one is in the right place it's the ribbon cable connector around the wrong way so mine is red line to toward pin 10.

With this you can update all china clone bdm 100 to 1255c, that means versions 1236 1242 & 555pro

Hi, can somebody give me the update for BDM, please, this link is dead, another too, very need it,

[ricards99]

hi,
i am new in bdm world, it's the first time i try to use it, i have china clone and do update as descripted in first post and i have this:
without connected device i have this look when running sof:

and with device connected i have another soft look when running:


is this normal or no? thank you
i have china clone grey BDM100 device

Run 2 then run 1
And you will have normal BDM100 working.
