<hr />
<div>== Installation ==<br />
Everything except U-boot is already present in the Generic ARM tarball on the download page.<br />
<br />
=== Compile U-boot ===<br />
Download the latest stable tag from the u-boot repository<br />
<br />
git clone --depth 1 --branch v2023.04 git://git.denx.de/u-boot.git<br />
<br />
then configure and compile u-boot<br />
<br />
make CROSS_COMPILE=arm-linux-gnueabihf- A20-OLinuXino-Lime2_defconfig<br />
make CROSS_COMPILE=arm-linux-gnueabihf-<br />
<br />
This should output a combined SPL file with u-boot called <code>u-boot-sunxi-with-spl.bin</code><br />
<br />
=== (OR) Using U-boot from NetBSD ===<br />
[https://ftp.netbsd.org/pub/pkgsrc/current/pkgsrc/sysutils/u-boot-a20-olinuxino-lime2/index.html NetBSD u-boot] may also be used to complete the steps below. After extracting latest tarball, /share/u-boot/ directory contains <code>u-boot-sunxi-with-spl.bin</code>.<br />
<br />
=== Prepare an SD Card ===<br />
Firstly, erase the first part of your SD Card including the partition table). <br />
<br />
dd if=/dev/zero of=${card} bs=1M count=1<br />
<br />
Secondly, create a DOS partition table and add a primary partition to your card. <br />
<br />
fdisk /dev/sdX<br />
<br />
Start the partition at sector 2048, change its type to W95 FAT32, and set its bootable flag.<br />
<br />
Finally, create a FAT filesystem on the new partition. <br />
<br />
mkfs.fat /dev/sdX1<br />
<br />
=== Copy Data to the SD Card ===<br />
Copy SPL with u-boot to the SD Card offset by 8KB (specific to Sunxi). <br />
<br />
dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8<br />
<br />
Mount the partition and extract files from the Generic ARM tarball onto it. <br />

=== After Installation ===<br />
The default login is <code>root</code>, HDMI should work out-of-the-box, ethernet is off by default. Use <code>setup-alpine</code> to complete the remaining configuration. The Installation page should guide you from here.</div>Sagaracharya
