# Installation -## A10 / A20 / A31 based boards +- Download or build **armv7.img** (32-bit) or **arm64.img** (64-bit) from NetBSD -current +- Write the image to disk: **dd if=armv7.img of=/dev/rld0d bs=1m conv=sync** +- Install a board-specific U-Boot (2017.07 or later) from pkgsrc to the SD card: **dd if=/usr/pkg/share/u-boot/<boardname>/u-boot-sunxi-with-spl.bin of=/dev/rld0d bs=1k seek=8 conv=sync** + +# Tips and tricks + +## Video overscan compensation + +On some television models, the borders of the screen may be cut off. If your television doesn't have an option to disable overscan, you can enable overscan compensation by entering the following commands at the U-Boot prompt: -* 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.

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.
