Try to read on the board or removed MCU?
Which processor trying to read?
Post your schema interface.
Hi Mates,
After more than a month-long spent trying with Motorola Cracker SW I dont get success with them at all, reset... reboot... reset... reboot forever! Can someone help me to a new try with the proved copies of them, it can be v4.3 and/or v6.2 or any. By the way, it has been proved that there is no problem with my MAX232 based interface , working fine. This is done by the other SW and the good Moto MCUs which using the similar interface. Many thanks.

Hi Mates,
The MCUs tried are A8(QFP64,c96n),A1FN(PLCC52, D26E),E9(QFP64,E28B),811E2 (DIP,C16J),K4(PLCC84, D67F) and F1(PLCC68,F43V & only with other program) with on the boards and removed (with X-tal 4 or 8 Mhz connected). All are working fine, readable and programmable with other program which requiring the same interface but non with Moto Cracker I have. I built interfaces both the circuit of single MAX232 and the MAX232 with LS245, found on the net. I'm aware that there are some mislabel/minor mistake on the circuits but they were corrected during build up. Unfortunately I lack the know-how to use SW to redraw them. Both circuits are working with most combinations.
With the hope that the new copies of the SW will help me to verify the problem.
If you think that the problem of SW, here MotoCrack v6.2

Thank you mates. Try again with the v 6.0 and v7 ok from arturkob and v6.2 from car235 with all the MCUs, still no work. Restarts all the time but booting not success. I just think these SW copies are identical to the ones I have had. The v 7 ok is said to have some bug in it and I quite agree as the displayed EEPROM
address at least for A8 is wrong. I'm still quite sure that there is nothing wrong with my HW interface, MCUs and
the connection, retesting again with other SW is going well. Now, no more idea what are the puzzles behind. My PC is Pentium3 700 Mhz, XP SP3 and with the true RS232 com port. Mates, still need your help, any good trick from your experience to overcome this to share. Thanks.
Hello.
And the schematic and conections ... can help me ?
Thank?s
I have never had no problems with it what so ever you are not trying to use a usb to rs232 adaptor. UIt also works with other off the shelf hardware.
pullup R=1k to rx and tx to +5V

What HW is for reading HC912 with motocracker 7 ? On BDM pin must be any spliter for RX/TX to one BDM wire. Know anybody this HW ?
Thank you all mates for the comments but even I try to +5V pull up to the RX and TX lines and with various versions of the SW all the results are of no change, the MCUs cannot boot up. This starts me to rethink on what any other possibility of fault on my boards even they works perfectly with the other two programs. Otherwise, should I give up and use other program instead.
And what you are using the scheme you can show? just add the face values of all elements
The scheme in MOTOR2_3.9.RAR by prusony should work, but I tried it with other similar program.
However, one more thing I would need to know. Can someone tell that all Motorola Crackers are compatible with Windows XP or not? Thanks.
