I have introduced some contents about Carprog reading Motorola processors,include:carprog reading carprog read MC68HC05,carprog read MC68H11xx,carprog read Motorola MC68HC912xx & 9S12,and in this post i collect content about carprog read MC68HC08 processor.
For Motorola MPU MC68HC08 series programming use A10 cable.
You can recognize Motorola (Freescale) MPU by maskset:
This MPU maskset is 4C11W
First digit “4” is mask series number, in practice can be 0, 1, 2, 3, 4 or 5, but for programming is not important.
Second 4 symbols is always letter + digit + digit + letter: this is processor maskset or encrypted processor type. All processor marking can by custom made, like “FORD S2234234” or SC2323454 but always you can find maskset on Motorola or Freescale processors.
Carprog Software & Hardware Recommend:
Before programming always select right processor type according maskset
How to connect CarProg programmer:
For HC08 programming use A10 cable 6 color wires:
BLUE – Reset signal to MPU;
ORANGE – PTC0 signal to MPU, must by high level;
BROWN – GND (ground);
GREY – PTA0 communication signal;
WHITE – IRQ +8-10V signal – in most cases you must pull-up this processor pin;
RED – switched +5V;
VIOLET – switched +12V;
CarProg ERROR messages:
Communication error – no communication between CarProg and Motorola processor -check MPU type, try to select quartz frequency manually.
To understand better onboard MPU programming problems, you can use table with right programming signals and voltages, described in table.
If you can’t read or write MPU with CarProg, check:
– did you was select right MPU type;
– did quartz resonator Q is the same in circuit board and in CarProg options;
– did all programming signals have right form and voltage;
