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! ***
|
|
|
|
|
|
|
|
|
|

|
|
|
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.
