Hello Lukas,
>> I installed MCUXpresso but MCUXpresso Config not installed automatically
Did you install MCUXpresso IDE or MCUXpresso Config Tools (stand alone)?
If you installed MCUXpresso IDE, can you attach here <workspace>/.metadata/.log
If you installed MCUXpresso Config Tools, can you attach here the <HOME>/.nxp/swtools.log
So we can look what is wrong? There's high chance the root cause is logged there.
Regards,
Libor
