Thank you for the reply.
I haven´t written any code. I just created a new project with the sdk-wizard.
Until now i found out that removing debug-console and using optimization reduces code size.
Now i was trying to play a bit with pwm, uard, adc and fsl-drivers. That works fine but im running out of memory very fast.
For example i copied a pwm-example from Keil-uVison5 to MCUXpresso to test it. But it needs about 150% of memory. Just for one PWM-example...
Im pretty sure that im doing something wrong but cant figure out what it is.
Are the fsl-drivers using a lot of memory instead of setteng the register by hand?
