MCU is secured.
Hello. I need to read dump from MC9S12DG128, mask 3L40K. It is from Astra H CIM module. I try with UPA, XPROG and CARPROG - no result.
I connected it like in XPROG documetation: 23 -BKGD, 40 - GND, 41 - VDD (+5V), 42 - RESET. I think it is correct.
CARPROG:
In carprog i am using A10 cable.
Red --> 41
Brown --> 40
Blue --> 42
Gray -->23
Oscilator is AUTO. When try to read there are only 5 attempts to read and nothing. The same with or without external power.
UPA:
In UPA i connected it:
9 --> 41
7 --> 42
5 --> 40
6 --> 23
Oscilator AUTO. If reset is not modified i have error: "Reset High Error". If I lift reset there is: "Device not respond". The same situation with USB power and external power.
XPROG:

No matter with adapter or without. Still error: "bootloader initialising error. Can`t to access BDM"
Please, help me. What I do wrong?

Ok, maybe. But what I must do to read this MCU?
Read with Xprog, look in menu for secured 9s12.
You need also Connect extal and ground

Ok, i read it like secured MCU. There is a BIG progress, connected to MCU and read eeprom. But during VERIFY there are a differences in some bytes.
I connected it like:

Is need 12-14 cm EXTAL twisted with GND?
I dont remove EXTAL from PCB but only remove capacitor after them.

make disable auto verify in xprog
and read the eeprom from mcu 2 times then check dumps for difference

I have two dumps:
3l40k.rar
All time when I red there is some differences
Lift extal and rst, check soldering xprog can read this mcu 100℅
Thanks for all. Problem is solved There wad bad connections between PINs from BDM adapter and my cables. When i squeeze cables reading is OK. Reading is good without lifting any pins of MCU. One more Time, thanks

I think it was XPROG
Hello one more time. I have still problems with xprog. After last reading I dont use my xprog. Today i try to read one more time mask 3L40K and... nothing. Connected the same as before. When i try to read this MCU there is CHECKING DEVICE and green LED on xprog, after few seconds there is INITIALIZING DEVICE, led change on RED and info DEVICE IS SILENT. RED led is still ON, turn of only when i disconnect USB cable. I also try to read the same MCU as at first but the same situation. What can be wrong?
Problem solved. I dont know why my xprog works only with one USB cable. I test 7 USB cables and nothing, only when i plug cable from xprog set main unit works good
Mates , XCLKS green need to be soldered on EZS or not with xprog and if YES where ?? Because 9S12 manual R260S claims DO NOT CONNECT GREEN WIRE !
