Hi All, I am working on adding EEPROM programming capabilities to e1000 driver on a custom i.MX6Q (automotive) board with i210 (8086:1531) connected over PCIe link. Unfortunately I am observing some bad/unexpected behavior that might indicate PCIe issues. What I am seeing is device(i210) enumerating on PCIe bus, however any accesses to its registers via its memory "window" result in either 0xFFFFFFFF or 0xDEADBEEF. I tried accessing various PCIe configuration registers of that device and it seem to work fine (as a part of that test I read out some AER registers and they didn't indicate presence of any PCIe link related errors). However when I boot Linux kernel (with 'igb' driver patched to recognize 8086:1531 VID:PID) on that board and run 'eepromARMtool' (Intel provided EEPROM programming tool) I can see it reading various registers correctly My questions are: - Is anyone currently using i.MX6 PCIe driver in 'next' branch? - Has anyone seen similar behavior on this particular controller and discovered the root cause? Any thought or advise are greatly appreciated.
