| − | === Creating Amlogic Package ===
| |
| − | | |
| − | '''Note:''' The following steps require an AMD64 platform.
| |
| − | | |
| − | <syntaxhighlight lang="bash">
| |
| − | $ git clone https://github.com/LibreELEC/amlogic-boot-fip
| |
| − | $ cd amlogic-boot-fip
| |
| − | $ mkdir -p output-bananapim5/
| |
| − | $ ./build-fip.sh bananapi-m5 ../u-boot/u-boot.bin output-bananapim5
| |
| − | $ hexdump -C -n 32 output-bananapim5/u-boot.bin | grep "40 41 4d 4c"
| |
| − | $ cd ..
| |
| − | </syntaxhighlight>
| |
| − | | |
| − | Verify that the new u-boot.bin contains <code>40 41 4d 4c</code> (<code>@AML</code>) at 0x10 onwards.

| − | == Board-specific installation notes ==
| |
| − | | |
| − | First follow the [[NixOS_on_ARM#SD_card_images_.28SBCs_and_similar_platforms.29|NixOS_on_ARM instructions to get the SD card image]] and decompress it.
| |
| − | | |
| − | Once the image has been decompressed, the Amlogic U-Boot package needs to be copied to byte 512+ inside the image (replace the image with the name downloaded and decompressed image):
| |
| − | | |
| − | <syntaxhighlight lang="bash">sudo dd if=amlogic-boot-fip/output-bananapim5/u-boot.bin of=nixos-sd-image-22.11.2620.de5448dab58-aarch64-linux.img conv=fsync,notrunc bs=512 seek=1</syntaxhighlight>
| |
| − | | |
| − | Then, copy the image onto the eMMC or sdcard using the [[NixOS_on_ARM#Installation_steps|the installation steps]].
| |
| − | | |
| − | In order to get a serial console output, it is required to replace <code>ttyAMA0</code> with <code>ttyAML0</code> in the <code>/boot/extlinux/extlinux.conf</code> file inside the image.
| |
| − | The easiest way is to just mount the respective folder after the image has been flashed on the SD-card
| |
| − | <syntaxhighlight lang="bash">
| |
| − | sudo mount /dev/sdX /mnt/
| |
| − | sudo sed -i 's/ttyAMA0/ttyAML0/g' /mnt/boot/extlinux/extlinux.conf
| |
