- NXP LS1043A-RDB
- ***************
- This file documents the Buildroot support for the LS1043A Reference Design Board.
- for more details about the board and the QorIQ Layerscape SoC, see the following pages:
- - https://www.nxp.com/design/design-center/development-boards-and-designs/LS1043A-RDB
- - https://www.nxp.com/products/LS1043A
- 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), but has a slower release cadence than LF. The currently used
- tag is lf-6.12.34-2.1.0, which is in line with the latest LF tag. Generally, in
- Buildroot, the latest Linux Factory release tag is always 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-6.12.34-2.1.0
- - atf (fork), lf-6.12.34-2.1.0
- - uboot (fork), lf-6.12.34-2.1.0
- - qoriq-fm-ucode (blob), lf-6.12.34-2.1.0
- - linux (fork), lf-6.12.34-2.1.0
- - fmlib, lf-6.12.34-2.1.0
- - fmc, lf-6.12.34-2.1.0
- Build
- =====
- First, configure Buildroot for the LS1043A-RDB board:
- make ls1043a-rdb_defconfig
- Build all components:
- make
- You will find in output/images/ the following files:
- - bl2_sd.pbl
- - fip.bin
- - fsl_fman_ucode_ls1043_r1.1_106_4_18.bin
- - fsl_fman_ucode_ls1043_r1.1_108_4_9.bin
- - fsl-ls1043a-rdb.dtb
- - fsl-ls1043a-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/ls1043a-rdb/genimage.cfg.
- Boot the LS1043A-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] = 10110011
- SW4[1:8] = 00100000
- SW5[1:8] = 00100010
- (SW5[1:8] and SW4[1] should be set to 001000000_0 for the SD card boot)
- - 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
