Hi,
You are most welcome to the test team for both the LT1 ECMs. The procedure is for bricked (broken) ECMs and if your OBDII unit isn't broken, I think that there are much better tools to tune/work...

I will just start another thread. Regret the hijack actually. Somehow I inserted a focus of mine and the XDF is an important topic. Did you get anywhere understanding the vectors?

Hi Carl,
Sounds OK. I will start working on instructions. Plan is that we will never need flash chips, sockets or programming equipment. I want to keep the conformal coating intact. Let's program...

Great news. I have tested routines for checking the ID, programming along with VPP On and Off. I assume that you have some different need but if not, I can just send you the VPP off.

Still...

Done. Here is my proposed code. Execute and it sends 447 $80 byte messages with the reply $06 $55 and the last one is marked $06 $A0



D_SEND_ALDL EQU $0008 ; SEND ALDL MESSAGE...

It will be hard for me to get to that format. My loader takes: [DEVICE ID] [LENGTH] [MODE] [MESSAGE …] [CHECKSUM]

In the case of mode $06 (that is all I look for/process) the first two bytes of ...

Code you need is below, I included both turn on and off. Port G is a factor on the Tside but not here. Analog goes straight to the processor inputs. Let me know if there is anything else that can...

I think it is the way I stated in the rambling explanation BUT not 100% sure because my TSide is not connected or powered. I need to get this back working.


All depends on the function of the...

I have had a look into the issue of lighting up VPP from the ESide. Not sure why it is so complex but I will explain what I see and request a little help...

On the Eside, the small 8pin soic...

Thank you. Is the device $F4 for both T & E sides?

Hi,
Yesterday I wrote some code that dumps out the content of flash in bootstrap mode. To do this, it was necessary to remove both bootstrap ROM and EEPROM from the memory map. This done, the...

Looked it up for you... With our crystal frequency the two speeds are 1,890 and 12,288. As I previously mentioned, my serial cable does not work at 12,288.

User sends $FF and IF received...

I agree, VPP is common through the ribbon cable. What about enable for the chip?? I don't know which pin, but it must also be across the ribbon. My guess is that there is a multidrop and that the...

Not happy w that. can you try messing with the "compatibility mode" setting. It's the same code I sent before compiled for x86 under visual studio.

In my setup, i ground both mode pins
First byte is $FF. In my case that is all that works but again I suspect the problem is my (*(*&^6 serial cable
No ht high baud isn't 8192. I can tell you what...

Yes that is what I think will work easy.

Can't use ALDL i/o in bootstrap. The internal rom echos received data this would get looped back and mess the load. One concern I have is making sure that the aldl driver chip doesn't mess things...

Please confirm... You think the Tside turns on VPP through the port replacement part port a bit 7?

I believe that the VPP is generated on the ESide by the small 8pin part center just below the heat spreader bar. I have not yet done a schematic for the Eside and do not know the part number for that...

While debugging the ESide routine for setting VPP to 12V, I decided to modify the result codes. Should the ignition voltage be out of range OR the VPP be out of range, an error message is generated....

It would be best if it fit into your tool. I'm not sure how to do this... If you can give me a hand I will see if we can make this happen.

I have not yet tried the TSide. The parts I need from...

Please give this a try

While on this posting storm, I just found one more thing. With respect to the 68HC11 noise flag, I wanted to understand what the issue is. Seems that there are problems with the baud rate in these...

Hi,
I did not try to describe the overall plan, because I was not sure what was possible. Ok, so here goes:

My assumption is that a bricked module corrupted FLASH. Obviously if the unit is...

First up, sorry bout the lack of destructions. I forgot to give any. Will do better as this all moves along.

Second, If need be with the push of a button you could have had 32bit. Easy done, just...
