| This file documents the Buildroot support for the LS1028A Reference Design Board. |
| |
| for more details about the board and the QorIQ Layerscape SoC, see the following pages: |
| - https://www.nxp.com/design/qoriq-developer-resources/layerscape-ls1028a-reference-design-board:LS1028ARDB |
| - https://www.nxp.com/LS1028A |
| |
| for the software NXP LSDK (Layerscape Software Development Kit), see |
| - https://www.nxp.com/docs/en/user-guide/LSDKUG_Rev21.08.pdf |
| |
| the components from NXP are: |
| - rcw, LSDK 21.08 |
| - atf (fork), LSDK 21.08 |
| - uboot (fork), LSDK 21.08 |
| - cadence-dp-firmware (blob), LSDK 20.12 |
| - linux (fork), LSDK 21.08 |
| |
| Build |
| ===== |
| |
| First, configure Buildroot for the LS1028ARDB board: |
| |
| make ls1028ardb_defconfig |
| |
| Build all components: |
| |
| make |
| |
| You will find in output/images/ the following files: |
| - bl2_sd.pbl |
| - fip.bin |
| - fsl-ls1028a-rdb.dtb |
| - Image |
| - PBL.bin |
| - rootfs.ext2 |
| - rootfs.ext4 -> rootfs.ext2 |
| - sdcard.img |
| - u-boot.bin |
| |
| Create a bootable SD card |
| ========================= |
| |
| To determine the device associated to the SD card have a look in the |
| /proc/partitions file: |
| |
| cat /proc/partitions |
| |
| Buildroot prepares a bootable "sdcard.img" image in the output/images/ |
| directory, ready to be dumped on a SD card. Launch the following |
| command as root: |
| |
| dd if=output/images/sdcard.img of=/dev/sdX |
| |
| *** WARNING! This will destroy all the card content. Use with care! *** |
| |
| For details about the medium image layout, see the definition in |
| board/freescale/ls1028ardb/genimage.cfg. |
| |
| Boot the LS1028ARDB board |
| ========================= |
| |
| To boot your newly created system: |
| - insert the SD card in the SD slot of the board; |
| - Configure the switches SW2[1:4] = 1000 (select SD Card boot option) |
| - put a DB9F cable into the UART1 Port and connect using a terminal |
| emulator at 115200 bps, 8n1; |
| - power on the board. |
| |
| The Cadence DP (Display Port) firmware must loaded from uboot with the following commands: |
| |
| => ext2load mmc 0 0x80000000 /boot/ls1028a-dp-fw.bin |
| 102464 bytes read in 24 ms (4.1 MiB/s) |
| => hdp load 0x80000000 0x2000 |
| Loading hdp firmware from 0x0000000080000000 offset 0x0000000000002000 |
| Loading hdp firmware Complete |
| => boot |
| |
| The interfaces of Ethernet switch (Felix DSA) are bring up with the following commands: |
| |
| ip link set eno2 up |
| ip link set swp0 up |
| ip link set swp1 up |
| ip link set swp2 up |
| ip link set swp3 up |
