PICe legacy interrupt issue in i.MX7

Discussion created by Anil Sasidharan on May 11, 2017



We are trying to get a WiFi module working with PCIe interface on Embedded Artists i.MX7 Dual COM board for one of the ongoing projects. At present we are checking kernel version 4.1.15 (based on NXP's sources).

For some strange reason, PCIe legacy interrupts are not working. Has anyone experienced similar issues with i.MX7 platforms? If yes, how to fix it?

As an additional experiment, PCI-MSI interrupts are enabled in the same kernel and tested, but the interrupts still not working. Really appreciate any help on this.


Warm Regards,
