You can use this diagram without Jlink interface. Work OK. carprog.jpg
Rremember use the very short wires for conect. Max 6 Cm.
Hi. I tried to reprogram my carprog, but without succes.
The first time I removed the memory from the board. Then I reset the MCU with pin 55 to + 3.3v for 20 seconds. After I connected pin 55 to GND. When I click detect, it does not find it.(I use J-link v8)
Can someone help me? I have attached some images with the connections. Thanks !

it doesn't matter how long the wires are.leave more time connected to 3.3V, the reset can take more than 20 seconds.when you try to connect to the processor, pin 55 must be disconnected, only after you finish programming you put it to GND.

can I please ask for purpose reflashing MCU?
"can I please ask for purpose reflashing MCU?"
Because Car prog have one internal uses counter,and uses is = 0 not found more. With reflash MCU ,the uses counter is reset and carprog found again.
yes i have it so does everyone else more or less
it is on every forum on the internet
PLEASE NOT CONNECT USB MY jTAG
