Hello,
I have a simple program where on one GPIO pin I turn on/off led (17)
and on second pin (23) a register a button.
This work normally, but when I restart RPI and start the program, LED
won't turn on. Button is registered normally.
After I close the program and reopen it everything is working
normally.

I try on startup open and close gpio and again open but no success.
I have SPI turn on at boot. I also wait 30sec. before first run of the
program.

Does anybody have any suggestion?
Regards, Matija
