This file documents the Buildroot support for the LS1046A Reference Design Board.

for more details about the board and the QorIQ Layerscape SoC, see the following pages:

- https://www.nxp.com/products/LS1046A

Layerscape platforms are officially supported by NXP under the Layerscape
Debian Linux SDK (LDLSDK). This uses components from Linux Factory (project
common with i.MX), currently tag lf-6.6.36-2.1.0, two releases behind the
latest lf-6.12.3-1.0.0. In Buildroot, the latest Linux Factory release tag
is used, which may be considered pre-release software, as it may contain
features which are not yet documented, and it generally undergoes less testing.

For the software Layerscape Debian Linux SDK User Guide, see:
- https://docs.nxp.com/bundle/UG10143/page/topics/about_this_document.html
- https://www.nxp.com/docs/en/user-guide/UG10143.pdf

The components from NXP are:
- rcw, lf-6.12.3-1.0.0
- atf (fork), lf-6.12.3-1.0.0
- uboot (fork), lf-6.12.3-1.0.0
- qoriq-fm-ucode (blob), lf-6.12.3-1.0.0
- linux (fork), lf-6.12.3-1.0.0
- fmlib, lf-6.12.3-1.0.0
- fmc, lf-6.12.3-1.0.0

Build
=====

First, configure Buildroot for the LS1046A-RDB board:

make ls1046a-rdb_defconfig

Build all components:

make

You will find in output/images/ the following files:
- bl2_sd.pbl
- fip.bin
- fsl_fman_ucode_ls1046_r1.0_106_4_18.bin
- fsl_fman_ucode_ls1046_r1.0_108_4_9.bin
- fsl-ls1046a-rdb.dtb
- fsl-ls1046a-rdb-sdk.dtb
- Image
- PBL.bin
- rootfs.ext2
- rootfs.ext4
- 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/ls1046a-rdb/genimage.cfg.

Boot the LS1046A-ARDB board
===========================

To boot your newly created system:
- insert the SD card in the SD slot of the board;
- Configure the DIP switches
SW3[1:8] = 01000110
SW4[1:8] = 00111011
SW5[1:8] = 00100000 (select SD Card boot option)
- put a Micro-USB cable into the console port and connect using a terminal emulator
at 115200 bps, 8n1.
- power on the board.

Alternatively, SD card boot can also be selected from the uboot command prompt:
- insert the SD card in the SD slot of the board;
- put a Micro-USB cable into console Port and connect using a terminal emulator
- power on the board.
- press any key to stop at the uboot command prompt.
- run the following uboot command
=> cpld reset sd
