I didn't really have much time to work on more hardware support on CI20 but it's been a while since the last post so here's what I've got:
  • drivers for on-chip ehci and ohci have been added. Ohci works fine, ehci for some reason detects all high speed devices as full speed and hands them over to ohci. No idea why.
  • I2C ports work now, including the onboard RTC. You have to hook up your own battery though.
  • we're no longer limited to 256MB, all RAM is usable now.
  • onboard ethernet is supported by the dme driver.
There's also an unfinished driver for the SD/MMC ports.
The RTC is a bit funny - according to the manual there's a Pericom RTC on iic4 addr 0x68 - not on my preproduction board. I've got something that looks like a PCF8563 at addr 0x51, and so do the production boards that I know of. Some pins on one of the expansion connectors seem to be for a battery but I haven't been able to confirm that yet. Either way, since the main connector is supposed to be Raspberry Pi compatible any RTC module for the RPi should Just Work(tm), with the appropriate line added to the kernel config.
Some more work has been done under the hood, like some preparations for SMP support.

Here's the obligatory boot transcript, complete with incomplete drivers and debug spam:

On behalf of the NetBSD project, it is my pleasure to announce the first release candidate of NetBSD 7.0.

Many changes have been made since 6.0. Here are a few highlights:

  • Greatly improved support for modern Intel and Radeon graphics hardware through a port of the Linux DRM/KMS code. Most X.Org components have been updated as well.
  • ARM multiprocessor support
  • Support for new ARM boards, some of which are listed below:
    • Raspberry Pi 2
    • ODROID-C1
    • BeagleBoard-xM
    • BeagleBone
    • BeagleBone Black
    • Banana Pi
    • Cubieboard 2
    • Cubietruck
    • Merii Hummingbird
    • Marvell ARMADA XP
    • GlobalScale MiraBox
    • Kobo
    • Sharp Netwalker PC-Z1
  • GPT support in sysinst
  • Lua kernel scripting
  • Multiprocessor USB stack
  • Many improvements to NPF, the NetBSD packet filter
  • GCC 4.8.4 (and optionally, LLVM/Clang 3.6.1)

Binaries of NetBSD 7.0_RC1 are available for download at:

http://ftp.netbsd.org/pub/NetBSD/NetBSD-7.0_RC1/

Those who prefer to build from source can either use the netbsd-7-0-RC1 tag or follow the netbsd-7 branch.

Please help us out by testing 7.0_RC1. We love any and all feedback. Report problems through the usual channels (submit a PR or write to the appropriate list). More general feedback is welcome at releng@NetBSD.org. Your input will help us put the finishing touches on what promises to be a great release!
