First of all, thank you for your quick respond.
I checked the path you attached, but I can't understand, why are these source files within includes?
According to my idea there has to be a folder in the project, that contains the source files, like 'sources'.
Apart from this, I found the irq files I mentioned.
When I open the Project lib which is required to build my own project, I see the 'osa' and 'platform' folders. Within 'platform/uart/drivers' there are the uart specific files:
-fsl_uart_common.c
-fsl_uart_driver.c
-fsl_uart_driver.h
-fsl_uart_edma_driver.c
-fsl_uart_edma_driver.h
and that's it. I guess irq should be here.
