Xprog distroys dashes ?

**tachonow** · 15th May, 2011, 12:04 AM

I read this mcu with UPA at 5V power delivered by programmer and never fails.

**wsc** · 15th May, 2011, 12:11 AM

Yes but in my case the UPA can not read 3L80R secured

I just puttet 5 volts on the original input from the dash and slowy made it go to 13,8 volts.

at 6,5 volts the chip had 5,0 volts , it stayed 5,0 volts until the 13,8 was reached.
I did not test what would happen at 20 volts .....:-)

So I think my chip(s) need 5 volt.

So bad,( for me)

it's not the solution to my problems

any other suggestions ?

this is you chip

Hi!
I read same mcu with x-prog_m ver.4.5 on volvo v70 2007 dash.
Last year I dont have problem my x-prog.(I use with micronas , mpc , secured mcu...)

Sorry for maybe stupid questions,

When I leave gnd on the dash and give the + an external 3,3 volts would that work ?

**grinovsky** · 15th May, 2011, 02:09 PM

yes ,work fine

**gadroulll** · 15th May, 2011, 06:45 PM

i never use power supply to xprog . usb can reach the 5 v and also 9 volts .

That's not true. Read datasheet. 9S12DG128B works with 5V

**grinovsky** · 15th May, 2011, 07:04 PM

no,read the thread and you will find that this guy have distroy 50% of his chips by using 5v
but if you can give to us other reason!!!

That is just bullshit. I read/write several 912, 9S12 and 9S12X
they all work with 5V. Just read datasheet and you will see it.

Possible reasons could be everything starting by bad xprog clone, activated security which results in locked bdm port.

first step solder coax wire and check if xprog-m works with 9s12 secured option. in this case it should bypass security and connect to it.

second step is desolder mcu and read with xprog using parallel programming.

Vcc out from xprog is regulated 0-5V. if you kill motorola maybe you select wrong device and xprog not regulated corectly Vcc? or your xprog is faulty.
additional resistor to vcc is unnecessary.

We did measure the volts it is 5 volts that comes out of the Xprog.
We selected MC(s)12 and then the MC9S12-Flash

What do u mean with :
solder coax wire ,..where should we do what ? :-)
(we are real newbees , sorry) do u have a picture of what we should do ?

and what do u mean with parallel programming ? Thnx

Select Motorola HC(S)12-secured -> MC9S12-FLASH-secured.

Click show connection diagram. then you will see that it needs to additonal wires (coax signal + gnd for shielding)
extal has to be connected to the oscillator pin. the other one to gnd.

ok wil try that
