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
