Load the U-boot and Linux Kernel with Script

There is a tool available in $yoctoDir/sources/load-uboot-kernel folder which can be used to load the u-boot and kernel automatically.

Setup on Ubuntu 18.04

# install python and basic modules for virtual environment
$ source setup-load-env.sh

Usage

The macros provided by option like -m $machine have higher priority than macros in config.py, if there is no options provided, this tool parse the macros in config.py file.

Method 1: Use Macros in config.py file

User just need to update the config.py file then run LUK.py, this is a better choice when user want to load manually. 

# Update config.py file for the Macros you want to change like BOOTTYPE, EMULATOR,COM_PORT, then run
$ sudo python3 LUK.py

Method 2: Change Macros via options

Options from user have higher priority, when both options specified and macros in config.py, the tool will use options and keep the config.py no change, this is a better choice when user want to load in automation testing. 

# please provide mount username and password if you want to copy images from share folder like //shared/folder
$ echo {mount-username} >username.txt
$ echo {mount-password} >password.txt

# Just load with nfsboot, and no need to copy files
$ sudo python3 LUK.py -b nfsboot -m adsp-sc584-ezkit --ipaddr 10.100.4.50 --serverip 10.100.4.174

# No need to update uboot and load with ramboot with providing deploy folder
$ sudo python3 LUK.py -b ramboot -m adsp-sc584-ezkit -f /tmp/deploy/images/adsp-sc584-ezkit

# Only update uboot, not load kernel, 
$ sudo python3 LUK.py -m adsp-sc584-ezkit --updateUboot -e 2000 --ipaddr 10.100.4.50 --serverip 10.100.4.174

# Update uboot and load with nfsboot with providing deploy folder
$ sudo python3 LUK.py -b nfsboot -m adsp-sc584-ezkit -f /tmp/deploy/images/adsp-sc584-ezkit/ --updateUboot -e 2000 --ipaddr 10.100.4.50 --serverip 10.100.4.174

# Update uboot and load with nfsboot with providing deploy folder using dhcp
$ sudo python3 LUK.py -b nfsboot -m adsp-sc584-ezkit -f /tmp/deploy/images/adsp-sc584-ezkit/ --updateUboot -e 2000 --dhcp

    -b BOOTTYPE, --bootType=BOOTTYPE
                          Specify the boot type like nfsboot,ramboot or sdcardboot, you can change BOOTTYPE in config file
