-## A10 / A20 / A31 based boards +# Installation -* Start with an ARMv7 image from *evbarm-earmv7hf/binary/gzimg/* such as *beagleboard.img* -* Download a U-Boot build for your board - * A10/A20: Download from the linux-sunxi web site - * A31: The standard u-boot-sunxi tree doesn't support A31 yet. Until sun6i support is merged, a build is available at -* Write the *u-boot-sunxi-with-spl.bin* loader to the base image: -[[!template id=programlisting text=""" -# dd if=u-boot-sunxi-with-spl.bin of=beagleboard.img bs=1k seek=8 conv=notrunc -"""]] -* Write the image to an SD card. -* Copy the kernel (netbsd.ub) for your board to the root of the MS-DOS partition. -* Create or edit uEnv.txt on the MS-DOS partition: -[[!template id=programlisting text=""" -bootargs=root=ld0a -uenvcmd=mmc dev 0; mmc rescan; fatload mmc 0:1 82000000 netbsd.ub; bootm 82000000 -"""]] - -## A80 based boards - -* Cubieboard 4 SDK (lubuntu) U-Boot env: -[[!template id=programlisting text=""" -baudrate=115200 -boot_normal=fatload mmc 0:1 20007800 uimage;bootm 20007800 -bootcmd=run setargs_cubie boot_normal -bootdelay=3 -console=ttyS0,115200 -console1=tty1 -init=/init -loglevel=8 -mmc_root=/dev/mmcblk0p2 -setargs_cubie=setenv bootargs console=${console1} console=${console} root=${mmc_root} loglevel=${loglevel} -stderr=serial -stdin=serial -stdout=serial -"""]] - -# Big (endian) fun - -You can run this boards with a little endian (this is the default and implied by above install instructions) -or with a big endian kernel and userland. However, kernel and userland endianness needs to match. - -To build a big endian release (or sets) use -[[!template id=programlisting text=""" -./build.sh -m evbearmv7hf-eb -"""]] -where -eb means endianness big, hf is hardware floating point support, and earm is the modern "extended" ABI for ARM CPUs, and finally v7 is version 7 of the supported instruction set. - -# FEX scripts - -Board configuration scripts can be found here: . You can compile them with the "fex2bin" tool found here: . - -To use, copy the compiled FEX to your MS-DOS partition, load it with U-Boot, and then tell the kernel where to find it with the "sysconfig=" boot option. For example, uEnv.txt on a Cubieboard2 might look like this: - -[[!template id=programlisting text=""" -bootargs=root=ld0a sysconfig=0x43000000 -uenvcmd=mmc dev 0; mmc rescan; fatload mmc 0:1 43000000 cubieboard2.bin; fatload mmc 0:1 82000000 netbsd.ub; bootm 82000000 -"""]] - -Some pre-compiled .bin files can be found here: - -# Framebuffer console - -To use HDMI for the console device, add *console=fb* to bootargs in uEnv.txt. - -If the connected display does not let you disable overscan, you can add a margin to the framebuffer by with the *fb.margin* bootargs option. For example, to set a 25-pixel margin around the screen, add *fb.margin=25* to uEnv.txt - -# HDMI audio - -The default audio device is the analog audio codec. To change the default device, use the *audiocfg* command: - -[[!template id=programlisting text=""" -a31# audiocfg list -0: [*] audio0 @ awinac0: Allwinner CODEC A31, 2 playback channels -1: [ ] audio1 @ awinhdmiaudio0: Allwinner HDMI 1.4, 2 playback channels -a31# audiocfg default 1 -setting default audio device to audio1 -a31# audiocfg list -0: [ ] audio0 @ awinac0: Allwinner CODEC A31, 2 playback channels -1: [*] audio1 @ awinhdmiaudio0: Allwinner HDMI 1.4, 2 playback channels -"""]] - -# Board specific notes - -## Merrii Hummingbird A31 - -There doesn't appear to be a meaningful way to generate a MAC address on these boards.
