And once you're there you'll need AR9285 support in athn(4) as well. Or swap in a supported card. I suppose there's no wifi whitelist in BIOS? ;)

I'm not sure which is which in the dmesg: imxesdhc0 at imx0 sdmmc0 at imxesdhc0 imxesdhc1 at imx0 sdmmc1 at imxesdhc1 ... sdmmc1: can't enable card -d

The commited VM_MAX_KERNEL_ADDRESS fix includes a page more memory than what's in the snap, it would be nice to confirm that the committed version works as well. The eeprom is hooked up via i2c and will need imxiic in novena_devs[] and likely some additional imxiic changes from Patrick. Getting at the atheros wlan/mini pcie slot would need something along the lines of Patrick's imxpcibr work. Audio looks to need a new driver for the ES8328 hooked up to imx via gpio/i2c?

Compiling u-boot is painful, I tried to do it natively on bbb but gave up as it seems to expect linux headers. Just modifiying uEnv.txt is much easier.
OpenBSD on Kosagi Novena open-source ARM board/desktop/laptop
Hi, Thanks to jsg@, the latest snapshot releases of OpenBSD will boot on the Novenai open-source laptop (http://www.kosagi.com/w/index.php?title=Novena_Main_Page). It's still very rough: no SMP, flaky USB and support for the eeprom (so no MAC addr on the IMX ethernet), but it gets to multi-user and could probably compile its own kernel given the chance. http://pastebin.com/raw.php?i=dr2qZSi2 is a boot log To try it out, the easiest way is to setup a tftp server and configure DHCP to tell Novena about it. Then boot/reset with the user button held down, ^C when prompted (be quick, you only have a couple of seconds) and issue the following u-boot commands: setenv machid 10ad setenv loadaddr 0x1080 dhcp bootm Note that u-boot doesn't seem to fully reset the ethernet controller/MAC. If you experience partial transfers that abort due to timeouts during the 'dhcp' command then a workaround is to completely remove power from Novena and try again after a minute or three. If you can get an installation completed (the imxenet is pretty flaky, possibly because of an all-0 MAC address), then you'll also need to copy bsd*.IMX.umg to the /boot partition of the sdcard under Linux (OpenBSD can't access the sdcard yet) and arrange uboot to fatload it from there. Something like: setenv machid 10ad setenv loadaddr 0x1080 fatload mmc 0 0x1080 bsd.IMG.umg bootm I baked these sequences into u-boot by following the instructions at http://www.kosagi.com/w/index.php?title=U-boot_PVT_Notes and modifying include/configs/novena.h with the additional commands, but it's also probably possible to put them in the /boot/uEnv.txt file that uboot reads at startup. -d
