TULIP4041 Startup Question

[MeindertKuipers]

I have messed up something. I had this issue in an earlier firmware version and thought it was fixed. It might be a corner case due to timing of the FI output. I had some changes in my VS Code and GitHub configuration and things went wrong there.
A new firmware file is now on my GitHub. Please observe the following:
- follow the instructions in the documentation to go to BOOTSEL mode and upgrade firmware
- firmware now runs at 125 MHz (was 150 MHZ)
- FI output is fixed, and HP-IL now works
- FI input is broken, so you will see all flags active in the tracer, which is not true of course, to be fixed
- I have removed the sources as this is for a non-working configuration
- make certain that JP2 is closed, this enables driving FI
