Audi Chorus AUZ1Z M4 Blaupunkt 4BO 035 152B -UPA_USB

[KrystianPoland]

Hello, I have this radio. However, it is on Motorola and as usual it is a problem with these processors. I need a photo how to properly connect UPA-USB to the motherboard of the radio to read the code. Thank you in advance.

[rafal]

desolder and read in adapter - HC705
i sent for you eeprom from hc05 with code - you can compare

[KrystianPoland]

desolder and load the adapter.
Thanks for the program but is desoldering necessary?

Thanks for the program but is desoldering necessary?

learn to press something if somebody trying help too you............

[KrystianPoland]

ok J turn on my HotAir

[KrystianPoland]

Ok, I desoldered the processor and I don't see the option in the UPA USB name MC68HC705B32. Which processor should I choose? J tried different Motorola from HC05 to HC11 but non of them want to connect to the procesor in adapter
I tried different Motorola from hc05 to hc07 but none of them want to connect to the processor in the adapter

Somebody helps me?

[KrystianPoland]

Help please

Maybe this script will help.

HC05B32 ..............

PD3 ----[====]----- +5V
RESISTOR 1k0

PD4 ----[====]----- +5V
RESISTOR 1k0

[KrystianPoland]

Thanks a lot

Maybe this script will help.

J asked about this photo in first post but Rafal recomend desoldering Motorola and use adapter. Now j am desoldering motorola procesor in outside radio. Tomorrow j'm going to soldering motorola again and J give answer that working or not.
12V+ radio ON or OFF? Sorry for my english

HC05B32 ..............

PD3 ----[====]----- +5V
RESISTOR 1k0

PD4 ----[====]----- +5V
RESISTOR 1k0

pd3 and pd4 through 2xresisitors 1k and plus connect to pin 6 UPA-USB.

Do J think right?

[treran21]

pd3 and pd4 through 2xresisitors 1k connect to pin 9 (+5V) UPA-USB
pin 6 UPA-USB no connect

[KrystianPoland]

J connetced in your describe but still j cant connect with motorola.My conect:
PCB Radio pin number:
1- to pin 1 UPA
2- to pin 2 UPA
3- to pin 3 UPA
4- to pin 4 UPA
5- to pin UPA
6- 2x 1k resistors and connect with pin9 pcb radio and connect with 9pin UPA
7- to pin 7 UPA

maybe it will be easier

J tried in this adapter but UPA cant connect with Motorola
I tried different Motorola from hc05 to hc07 but none of them want to connect to the processor in the ad

[treran21]

wipe the contacts of the controller and the lamellas of the socket with alcohol
good contact is very important, check with a multimeter
Select 705b32 (b16) from the menu set the switch on the adapter to the correct position

There are no miracles

I give up - cleared everything, nothing works, I tried and adapted and MotorolaCracker V.6, I soldered on a spider and nothing. I used a standard converter on max232 and nothing.

[andm266]

The processor may not be working.
Solder it back and if the radio still works, try connecting as shown. I read this processor many times in a circuit without any problems.
I used MotCrack v6.2. and Max232 interface.
I think UPA should also read this as MC68HC705B16.

[KrystianPoland]

I'll connect tomorrow and let me know-where do you get this photo from? He comes from somewhere in Poland. Show me your 232 interface because I have two and none work

[andm266]

It is my foto.
I'm using an interface similar to this one, but I use only Reset, Txd, Rxd.

[KrystianPoland]

Unfortunately, UPA did not cope with this processor but I built a programmer on max232 (the diagram was sent by a colleague from the forum Zann) and the system was read. Thanks for all the help.
