• Building images
$ cd openil
$ make nxp_ls1021atwr_defconfig
$ make
# or make with a log
$ make 2>&1 | tee build.log
• Programming U-Boot in SD card
Power on the LS1021A-TWR board to the U-Boot command environment, then use the following commands:
=>tftp 81000000 u-boot-with-spl-pbl.bin
=>mmc erase 8 0x500
=>mmc write 0x81000000 8 0x500
#then reset the board
• Deploying kernel and Ramdisk from TFTP
1. Set the U-Boot environment.
=>setenv bootargs ‘root=/dev/ram0 rw ramdisk_size=50000000 console=ttyS0,115200’
=>saveenv
2. Boot up the system.
=>tftp 83000000 uImage
=>tftp 88000000 rootfs.cpio.uboot
=>tftp 8f000000 ls1021a-twr.dtb
=>bootm 83000000 88000000 8f000000
3.4 LS1021A-IoT
The LS1021A-IoT gateway reference design is a purpose-built, small footprint hardware platform equipped with a wide array of
