- Subject: Re: [ECOS] How to enable serial interrupt of 16550
I am using the same Serial driver written in ECOS for 16c550 serial controller. & Able to Communicate (transmit & Receive ) data on serial port but not able to Enable the interrupt for that same port. I want to implement serial communication on interrupt.
Do i need ti change any ecos settings to enable that perticuler serial interrupt.
I tried to use function cyg_interrupt_create (....) & cyg_interrupt_attach(..) with given ISR function but it is not working
Pls guide me to solve this problem

You need to use the serial device driver for this board. Take a look
at the documentation for details on how to enable it.
