USB issues on OMAP3 (beagle/overo) with latest linaro-2.6.38 tree

by john stultz

Hey Nico, So I've been seeing USB issues on my beagle xm board with the latest linaro-2.6.38 tree, where when the system boots, lsusb will only show the hubs, but no devices. Andy reported seeing similar on his overo board, so I bisected the issue down to: 9e64bb1e9f0613093b3e34ac5402fcfef0dcc35a is the first bad commit commit 9e64bb1e9f0613093b3e34ac5402fcfef0dcc35a Author: Keshava Munegowda <keshava_mgowda(a)ti.com> Date: Tue Mar 1 20:08:19 2011 +0530 arm: omap: usb: Invoke usbhs core device initialization The usbhs intialization is invoked by all omap3 and omap4 variant board files. Signed-off-by: Keshava Munegowda <keshava_mgowda(a)ti.com> Signed-off-by: Felipe Balbi <balbi(a)ti.com> It looks like this patch is just converting the initialization over to usbhs, so it doesn't really point out the specific issue, but it does seem that something in the usbhs core isn't working properly. Any tips here? thanks -john The full bisect log is: git bisect start # good: [47dc59f22a6af00691a98975d05a8a1601714e1b] OMAP4: PandaBoard: remove unused power regulators git bisect good 47dc59f22a6af00691a98975d05a8a1601714e1b # bad: [8061f3a885ec3538bf405ff3957c205b1ab2aae4] mach-ux500: correct MMC/SDI parameters git bisect bad 8061f3a885ec3538bf405ff3957c205b1ab2aae4 # bad: [1c49cb09b5666aa0d6df3b58f6c621df92c5dd44] Merge commit '05f6894' (omap-for-linus) into linaro-2.6.38 git bisect bad 1c49cb09b5666aa0d6df3b58f6c621df92c5dd44 # bad: [0cd3fd78e5951c1631ee60a2026603d63c671d98] Merge commit '9ced9f0' (rmk/devel-stable) into linaro-2.6.38 git bisect bad 0cd3fd78e5951c1631ee60a2026603d63c671d98 # bad: [23e0d1066f429ab44305e96fbff13f1793886277] usb: Refactor irq enabling out of usb_add_hcd() git bisect bad 23e0d1066f429ab44305e96fbff13f1793886277 # good: [c9642374d0e969e8c17f4f31cd1a2bd111634227] USB: fix unsafe USB_SS_MAX_STREAMS() definition git bisect good c9642374d0e969e8c17f4f31cd1a2bd111634227 # bad: [45d1b7ae205e39e95ec65747f8871661aaa105e4] usb-gadget: fix warning in ethernet git bisect bad 45d1b7ae205e39e95ec65747f8871661aaa105e4 # good: [37db3af11f02c2ccdf44a788694da16062a0333c] usb: otg: TWL4030: Update the last_event variable. git bisect good 37db3af11f02c2ccdf44a788694da16062a0333c # good: [181b250cf53233a7a7c6d7e1e9df402506712e93] arm: omap: usb: create common enums and structures for ehci and ohci git bisect good 181b250cf53233a7a7c6d7e1e9df402506712e93 # bad: [19403165c272cc4ed00c97973e7271714b009708] usb: host: omap: ehci and ohci simplification git bisect bad 19403165c272cc4ed00c97973e7271714b009708 # good: [2236396d4d23828a0875a4d447103d0ab48aed0b] arm: omap: usb: usbhs core device initialization git bisect good 2236396d4d23828a0875a4d447103d0ab48aed0b # bad: [3b68ae73d8afa925807ebaae7eb14e2afd43f5b5] arm: omap: usb: cleanup ehci and ohci resources and devices git bisect bad 3b68ae73d8afa925807ebaae7eb14e2afd43f5b5 # bad: [9e64bb1e9f0613093b3e34ac5402fcfef0dcc35a] arm: omap: usb: Invoke usbhs core device initialization git bisect bad 9e64bb1e9f0613093b3e34ac5402fcfef0dcc35a

The dtc tool needed As the .dtb files will be naturally generated in the same kernel folder as kernel image sits, why do not we ship .dtb in the same folder as kernel image /boot? > to build the .dtbs is included with the kernel tree. > - Add relevant dtb files to boot partition in linaro-image tools The .dtb files will be generated and shipped with unique name, which comes from .dts file name. But I intend to use the generic name, maybe something like board.dtb along with l-m-c, just like we use zImage and u-boot for all platforms in boot partition, so that l-m-c does not need to encode platform specific dtb filename. Thoughts? -- Regards, Shawn
