Hello everyone,

I`ve tried to build a BlueSaab 6.1 and I seem to have got close but so far don't have a working one.

So far, I`ve been able to solder it all together and have loaded on the software via the FTDI header.
I`ve held down BOOT0 and reboot, the Arm chip has accepted the software and I`ve read it back out to confirm.

When plugged into the car however, I only get the Red Power light and no other sign of life.

The car (2005 9-5) already had a CD Changer.  Do I need to Divorce this first?  When cycling through Sources using the Steering Wheel controls, only CD,Radio and Tape show.

I`ve re-flowed the soldering on the Arm chip twice now, but it's never changed it's behaviour.

At present, I don't have a JTAG header soldered on.  Is there any other way to debug it?

Frank.
