I am using buildroot to build a kernel and rootFS for a beaglebone black. Buildroot is awesome and builds everything fine. The board boots up and all packages work properly. Unfortunately, USB seems to be badly broken. In the kernel I have USB driver enabled and USB Announce New Devices turned on. Googling around I find several people with the same problem, hotplug does not work at all, and no device I have tried shows up in dmesg or lsusb on cold or warm boot. A band aid is to use a powered USB hub (have not tried that). Some guys on the beagleboard.org IRC say to try a newer kernel version (3.14 or >) because beaglebone USB is fixed in newer kernel versions. Current buildroot beaglebone black kernel version is 3.12.10 In buildroot I used make beaglebone_defconfig. Under the Kernel menu, Custom Git repository is selected. The git URL is https://git.ti.com/ti-linux-kernel/ti-linux-kernel.git The custom repository version is 7f280334068b7c875ade51f8f3921ab311f0c824 The def config is board/beaglebone/linux-3.12.config How was the custom repository number (7f280334068b7c875ade51f8f3921ab311f0c824) derived? Looking on the TI gitorious site, I see they are working on kernel 3.15. How can I make buildroot use the newer version? How do I find the newer custom repository version? I tried to find my answer with google, but I must not be using the correct search term. Please excuse the newbish questions. Thank you, -- Dan Pattison Ethertek Circuits
