Fabio,
Good catch, but that doesn't resolve the issue i'm seeing here.
Any other ideas?
Do you still have issues after applying David's delay workaround?
Yes
Again, apologies for the late reply.
On my mx6qsabresd I noticed that:
- if U-boot has PCI driver enabled, then kernel hangs 100% of time.
That's because the PCIe core and PCIe PIPE PHY are not properly restarted. Do we have any software way to put the PCIe core to an initial state ? Same pro PIPE PHY ?
- if U-boot does not have PCI driver enabled, then the kernel boots
but does not detect my PCI card.
Well, that's some other shitness. I can get MX6SabreSDP to detect my card, but I have that 1-out-of-200 "phy link never came up" problem.
After applying David's workaround I can boot the kernel with PCI driver enabled in U-boot and the kernel does detect the PCI Wifi module.
OK. Even with David's patch or with FSL supplied patches, I still have the 1- out-of-200 failure case :-/
