MC9S08GT32A processor in a auto satellite tracking system for motorhome

[andrewstancliff]

Hi

Total newbie here who needs someones help

My problem is my auto tracking system in my motorhome is controlled by a MC9S08GT32A it has 16 different satellites preprogrammed into the system my problem is that recently SKY UK changed frequency on the channel the system uses to lock onto the satellite. I need to change this frequency to a new one that is still in use so my system still works.

I have made a S19 dump file of the MC9 but my ability ends there. can anyone point me in the direction of reading and editing the file?

Thanks in advance

Andrew

Sorry OM, your file contains no code -- only RAM contents.  I might assume your device is 'code read protected', or your tool wasn't getting it properly.

The GT32A code space occupies 0x8000-0xFFFF.  0xFFFE-F MUST contain a reset vector, whatever else it may contain.

Hi

Sorry here is the dump from 0x8000-0xFFFF

Those two code sets are pretty similar.  Mostly it looks like the second one has an 'added' subroutine from 0x800E-0x803B

Can you read-off any IC part numbers from 'important looking' parts to give some idea how this whole thing might work?

[andrewstancliff]

Sorry I have forgotten to say thank you for your help so far

Andrew Stancliffe

[egoodii]

No problem -- I feel for your 'unfriendly obsolesence'.

In any case, the code you've dumped doesn't contain anywhere NEAR enough 'intelligence' to do all that controlling and menu operations.  There are more smarts somewhere else...

[andrewstancliff]

Here is a picture of the PCB

[egoodii]

You're right -- there isn't much else there(!).  All I can say is if I search BSBE1-D01A I find Linux drivers that seem 'appropriately complicated'.  I'm afraid we may be dealing with a NIOS processor compiled into the FPGA and doing the major setup for the tuner.  I will dig a little deeper into the code you've got, but I don't expect to find much.  For instance, the Linux header looks to indicate about a hundred 'registers' to set up in the tuner...

[andrewstancliff]

I know it is a nightmare even the BDM pins are not standard.

I have also read the Cyclone 2 ic here is the jic file for that

[egoodii]

Nothing 'obvious' in there...

[andrewstancliff]

Does the following link help anything ? http://www.lyngsat.com/packages/skyuk.html

Can you see reference to

SID

VPID

APID

Beam EIRP (dBW) C/N lock

Sorry to be a pain but i am a novice on this type of work

[andrewstancliff]

The last system I had was easy to update with a null modem and hyperterminal this one is driving me mad. My hope was to find a list of 16 frequencies and just change them all to 16 UK channels to future proof myself......if only life was so easy! I have been trying to solve this for three weeks now and the manufacturer is less than helpful.

The strange thing also is that the BDM port doubles up as a FPGA port as well to a cyclone 2 EP2C5T144C8 note the 8 pin header bottom centre

The manufacturer updated these once before and used a cyclone pro which I have now bought but I had hoped it may have helped find comments listing the satellites as a clue.

The rj45 goes to a control unit with LCD display

Here is a photo of the board and a link to the user manual http://www.mobilsatplus.it/images/stories/files/User%20Manual.pdf

Viewed in THAT light, I guess your first post was also 'valid', but a little different???  Reset points to 0x807B, and THAT disassembly is attached here.  I just couldn't believe a 32K processor with <250 bytes of code in it...

[egoodii]

OK.  Well, there isn't much there!  The reset vector points to 0x80B2, and there is only code from from 0x8000 to 0x80DD.  I don't know how (if?) to save disassembly text out of the Codewarrior window, but two screen caps catch what little is there (attached).  I certainly don't see anything 'obvious' in there, like a string of 'frequency' numbers...just a few constants from 0x80BB thru 0x80CC.
