Plus you have to start somewhere!

Do you think the board is working?

How are you testing the circuits....bacis fw or are you using a signal generator or something like that?

First I start the board on the table with the connected input signal simulators. I simulate engine start from 0 to 400 engine revolutions.
Using a digital oscillograph and an 8-channel logic analyzer
I check the output signals of fuel, ignition, ....

I thought maybe you were applying an external signal to test drivers and such.....don't you need fw to "start the board"? To get the etpu to read the crank signal inout yoy show and generate the outputs you show?

The etpu can generate a crank/cam signal for testing too....we use it for o5e work and just jumper it to the inputs .....but it need fw to do anything which iis why I asked what you're using.

To simulate the signals of crank and cam sensors I'm using now -
ardu-stim
CrankWheelPulser.

I have a large archive of sensor waveforms, and it is constantly replenished.
I necessarily compare them with those that are on the Internet and often they are different.
For example, I studied the documentation for the Mercedes M113 engine and found the difference in the signals of the camshaft sensor.
