Hi Tony, the MMC4 problem is solved and the second SD slot works.
It was a small bug in our Pyra DT. The data lines were still pinmuxed as GPIOs...
Now, we have mmc1 - 4 all running.
BR, Nikolaus

Heh OK :)

Great good to hear!

Hey,
I've been testing the latest kernels (both vanilla mainline and Nikolaus' mods) and it seems ehci startup became unreliable. What I mean on some boots it works fine, on on others it's timing out:
[ 5.983585] ehci-omap 4a064c00.ehci: USB 2.0 started, EHCI 1.00 [ 6.000477] usb usb1: New USB device found, idVendor=1d6b, idProduct=0002 [ 6.007617] usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 6.015188] usb usb1: Product: EHCI Host Controller [ 6.020296] usb usb1: Manufacturer: Linux 4.5.0-rc4-letux+ ehci_hcd [ 6.026871] usb usb1: SerialNumber: 4a064c00.ehci [ 6.043032] hub 1-0:1.0: USB hub found [ 6.049426] hub 1-0:1.0: 3 ports detected ...

[ 23.313251] usb usb1-port2: Cannot enable. Maybe the USB cable is bad? [ 23.320182] usb usb1-port2: unable to enumerate USB device
Seems to mostly happen if I run "poweroff" and then boot by pressing the power button. No devices are connected to the USB ports. Curiously smsc95xx still works.
Do any of you see this issue? EHCI used to work reliably ~4.2 time. I hope to avoid bisecting as the problem is somewhat random...

Yes, since I have an OMAP5432EVM. I.e. it is almost always there (I don't remember the 3.8 or 3.11 kernels) but I didn't see that it has a significant effect. I have not yet seen on the Pyra hardware.
But before I make a false calmdown - it may be port3 where I see this.

Indeed.

I don't think I've seen this one with uevm or igepv5 so far.
