for i.Mx6Q the reference manual states about the EIM bus "External Interrupt support, RDY_INT signal function as external interrupt". My problem is that I can not find any further information about this feature. Looking in the description about external signals I can not find any interrupt signal. I have also checked in the IO Mux Tool and can not find any interrupt pin for EIM there either.
The use-case is a i.Mx6 connected to a FPGA thorugh the EIM bus. Then it would be nice to have some interrupt from FPGA to processor. Is this possible to solve with EIM or in some other way?
