Date: Sun, 1 Feb 2015 18:33:25 -0500 (EST) From: John Wehle <john@feith.com> To: ganbold@gmail.com Cc: freebsd-arm@freebsd.org Subject: Initial Amlogic aml8726-m6 and aml8726-m8 support files Message-ID: <201502012333.t11NXPOe028696@jwlab.FEITH.COM>
next in thread | raw e-mail | index | archive | help
Here's the initial release of support for Amlogic ARM SoC devices. It
supplies basic functionality, however it should by no means be considered
production ready.
Currently FreeBSD successfully boots to the login prompt on an aml8726-m6
board (the box seems to be some type of Visson ATV-102) as well as on an
aml8726-m8b board (a Hardkernel ODROID-C1) using a SD card and a serial
console.
Unshar into your FreeBSD 11.0-current source tree, review the README,
apply the patch, and have fun.

PatchJLW01 provides the necessary changes to the FreeBSD 11.0-CURRENT r278021
source tree which along with the additional source code accompanying this file
allows FreeBSD to be built for various Amlogic ARM based SoC devices.
X
Currently FreeBSD successfully boots to the login prompt on an aml8726-m6
board (the box seems to be some type of Visson ATV-102) as well as on an
aml8726-m8b board (a Hardkernel ODROID-C1) using a SD card and a serial
console.
X
The following support is included:
X
X Basic machdep code
X
X SMP
X
X Interrupt controller
X
X Timer
X
X Real time clock
X
X UART
X
X GPIO
X
X SD card
X
X USB
X
X Watchdog
X
X Random number generator
X
X PLL / Clock frequency measurement
X
X Frame buffer
X
There's also drivers for the I2C and the aml8726-m3 USB PHYS hardware in my
private source tree which are currently untested ... I plan to release them
at some point once I've actually tested them.
X
The MAC appears to be the DWC ... it shows slight signs of life on the Visson
ATV-102, however fails to reset on the ODROID-C1. Further investigation is
needed.
X
The u-boot sequence I use for the Visson ATV-102 is:
X
X video dev open 480p
X mmc rescan 0
X fatload mmc 0 0x80100000 kernel.bin
X go 0x80100000
X
The u-boot sequence I use for the Hardkernel ODROID-C1 is:
X
X video dev open 480p
X fatload mmc 0 0x100000 kernel.bin
X go 0x100000
X
The current FreeBSD driver doesn't program the video clocks so the u-boot
video commands are necessary in order for the frame buffer to be useful
(otherwise they can be skipped).
X
The SD card for the Visson ATV-102 doesn't need anything special beyond
creating a FAT16 and a UFS filesystem.
X
The SD card for the ODROID-C1 also needs to contain the Hardkernel bootloader
as well as u-boot ... sd_freebsd_odroidc1.sh can be used to prep the card.
I obtained the bootloader and u-boot from the boot subdirectory of
ArchLinuxARM-odroid-c1-latest.tar.gz which is available at:
X
X http://archlinuxarm.org/developers/downloads
X
The u-boot source code is available at:
X
X https://github.com/hardkernel/u-boot/tree/odroidc-v2011.03/
X
which also contains a prebuilt bootloader in the sd_fuse subdirectory ...
however currently there's no prebuilt u-boot present.
X
The frame buffer driver is very rudimentary.
X
Currently the MMC driver occasionally times out ... it may simply be
due to the particular SD card I'm using or be due to a bug in the driver.
The problem seems to go away when things are power cycled.
X
The RTC currently doesn't survive a reboot and on the ODROID-C1 requires
the battery to be installed.
X
Enjoy,
X
