Hi, Before anyone starts throwing bricks in my direction, yes, I know it is not the Fedora way to apply ~200 patches to a stable kernel and release it.... ;) Several people seem to have been trying the F20 Alpha on their Wandboards, and there have been questions about the (lack of) hdmi driver, etc. etc. I'm running a 3.11.1, built from a src.rpm with Robert Nelsons patch set applied. (Or at least the Wandboard/IMX specific patches.) Hopefully, the situation with "mainline" Wandboard support will start to change with the 3.12 RC series, but until then, if you want more driver support than the "stock" Fedora kernel is providing, I've uploaded RPMS's and SRPM to the Community Squeeze repo. To use... yum install \ http://www.communitysqueeze.org/repo/community-squeeze-repo.noarch.rpm yum --enablerepo=community-squeeze-testing install \ kernel-3.11.1-300.2.wandboard.fc19.armv7hl imx-sdma-firmware \ brcmfmac-sdio-firmware (Ignore the fc19 dist tag in the kernel package name. It should be fc20, but I cross-compiled from a F19 x86_64 desktop, hence the fc19.) After install and before reboot, you'll need to edit /boot/extlinux/extlinux.conf and make sure the dtb file location is correct. (For me it wasn't and would have used the dtb file from the previous kernel install with the new kernel, which will result in no more functionality than you had before with the "stock" Fedora kernel.) ie. "fdt /dtb-3.11.1-300.2.wandboard.fc19.armv7hl/imx6q-wandboard.dtb" I've not had a monitor/TV attached, but from dmesg it looks like hdmi output should be working. On board sgtl5000 audio is working. Broadcom wi-fi is working. CPU governor support is working. SPDIF output is not currently working. (I think I saw a change in one of the "next" git trees that is required, on top the the two RN patches, to get that working, but I'm out of time.) NB1. imx-sdma-firmware package contains a single firmware file. I still don't think loading from ROM is working, so if you don't install the firmware package, on-board sgtl5000 audio, (which depends on sdma), might not be available. $ rpm -ql imx-sdma-firmware /lib/firmware/imx/sdma /lib/firmware/imx/sdma/sdma-imx6q.bin NB2. brcmfmac-sdio-firmware package contains the 2 firmware files you'll need for the wi-fi driver to function. $ rpm -ql brcmfmac-sdio-firmware /lib/firmware/brcm/brcmfmac-sdio.bin /lib/firmware/brcm/brcmfmac-sdio.txt NB3. Bluetooth.... In the CS repo, there is a package, brcm4329-bluetooth. $ rpm -ql brcm4329-bluetooth /lib/firmware/brcm/bcm4329.hcd /usr/lib/systemd/system/brcm4329-bluetooth.service /usr/sbin/brcm_patchram_plus ----- [Unit] Description=Broadcom Bluetooth bcm4329 After=syslog.target Before=bluetooth.service [Service] Type=simple ExecStartPre=/sbin/brcm_patchram_plus\ --timeout=6.0\ --patchram /lib/firmware/brcm/bcm4329.hcd\ --baudrate 921600\ --use_baudrate_for_download\ /dev/ttymxc2 ExecStart=/sbin/hciattach -n /dev/ttymxc2 any 921600 [Install] WantedBy=multi-user.target ----- The brcm4329-bluetooth.service file, uses "ExecStartPre=..." to load the firmware with brcm_patchram_plus. That appears to succeed. The "ExecStart=/sbin/hciattach -n /dev/ttymxc2 any 921600" seems to be failing. Not had time to look at it yet, but if anyone else has time to jump in and took a look, please do. NB4. Groans and moans for any breakages/regressions in my direction, please. Praise and thanks for his work on making the mainline kernel as functional as possible with the Wandboard at this early stage, to Robert Nelson.
