Title: ME7 reading of second CPU.
Post by: rkam on February 17, 2014, 10:06:47 AM
On Volvo I have to let the first CPU run like normal to get the 0xC5 response from the second.
The problem is that the second is rebooted every second or so.

If I ground the boot pin of the first and second CPU I can only get a response from the first one.

The first one through K-line and the second one is directly connected to TxD0 and RxD0

Fixed:
Removed a tiny something near a LM2901 that was connected to RSTIN.
Now I have to manually connect the spots left behind once, and then it runs without interruption and can be read with Minimon.
