After BSP update Udoo Quad/Dual board once again hangs on boot. On a new kernel disabling CONFIG_USB option is not enough to work around the troublesome usb host on Udoo Quad/Dual board. So in order to be future-proof it makes sense to disable usbh1 block in device tree rather than fine-tune kernel configuration after BSP updates.

[PATCH] ARM: dts: imx6qdl-udoo: Disable usbh1 to avoid kernel hang
|
|
|
|
Currently the kernel hangs when USB Host1 is enabled due to the lack of
|
|
support for controlling the USB hub clock and GPIO reset line.
|
|
|
|
Peter Chen has made several attempts to fix this problem, but his series
|
|
has not been applied yet, so better disable USB host1 for now to avoid
|
|
the kernel hang.
