It happened to be the i.MX6UL (with ARM Cortex-A7, right?) was most curious about. For embedded projects that don't require video or audio... the Cortex-A7 may be all the power those embedded projects require. I saw the SPI driver in the list of unfinished drivers. I also didn't think it would be hard to port SPI from a working project over to the iMX6. :) Some i.MX6UL SOMs are being priced in the $24-ish (ex Variscite DART-6UL) range, so at those low prices - > you'd think there are a lot of good embedded application problems waiting to be solved with embedded FreeBSD. :) I'm new to FreeBSD - but, I'm excited to learn more and try to make myself useful to the community. Thanks sir... --DJ Regan On Sun, Apr 2, 2017 at 12:44 PM, Ian Lepore wrote: > On Fri, 2017-03-31 at 09:11 -0500, DJ Regan wrote: > > According to wiki page... > > > > https://wiki.freebsd.org/FreeBSD/arm/imx6/ > > > > ...the last update of 'what works' vs 'what still needs to be done', > > was... > > > > FreeBSD/arm/imx6 (last edited 2015-02-02 01:54:07 by IanLepore > > ) > > > > ...what is the current state of iMX6 development? > > > > And, where can I start to help? :) > > > > Thanks, > > --DJ Regan > > Sadly, the status now isn't all that different.
