from chap17.pdf
The watchdog reset cannot occur while the C167 is in bootstrap loader mode!
I was referring to the can loader that I have, good spot, those seem to be a good source  IMHO it says that because you should have disabled it, it wont do it itself lol. |

Still, that concerns the internal wdt and the ~20Hz to an external ic is another matter.
I might have had a bad connection because now I have stable bootmode situation as long as I leave the 20Hz injection in place. When I remove it I can connect with VCDS again.
Something with my minimon code regarding K-line transciever is faulty.

Keep at it, well done  so several watchdogs, I'll skim the datasheet and see if I can help at all. |

Found another timer now which seems to output correct freq.
But I still have the problem that I cannot get my code to execute in boot mode.
It feels similar to what happens when power is incorrectly applied to ME7 in boot mode, it is boot mode but you cannot connect. (eg. with minimon or ME7eeprom)
But on the Haldex Ecu there is not power+ignition it's only power.
My boot code works on a plain ME7 ecu, there is nothing wrong with it codewise but I cannot get it to execute in the Haldex.
Anyone?

Code starting point being correct would be one idea.

But it dependent on the CPU rom I was thinking perhaps.... |

Damn, I'm tired, I need to get some sleep. Communication with Haldex gen1 works now, without touching the circuit board.  But I'm not sure about memory layout, will have to continue tomorrow. |

It can be read from more than one address. I used another but I see now that 0xC0000 also works. I had to make a correct read before sleep.  btw there is also a statement earlier in thread that does not seem correct about addressing and memory. |
