I can not find this configuration defined anywhere in my include/configs/.h file and includes, nor in configs/_defconfig and it is still defined in .config file after configuring u-boot. I am seeing this configuration defined in tools/Makefile. Is it default? Should I use #undef in me include/configs/.h or CONFIG_CMD_NET=n in configs/_defconfig? What is better?
Which module and BSP version are you using?
Assuming U-Boot v2016.11, this symbol is defined in cmd/Kconfig and is therefore should be defined or disabled in Kconfig. Now in Kconfig language, every configuration has a default (in this case default y
). All defconfigs are minimal configs in the sense of they only contain deviations from what is the Kconfig default. This is why you don’t see CONFIG_CMD_NET
in defconfigs. To disable a config symbol which is by default yes, you need to add a line like this:
# CONFIG_CMD_NET is not set
The automated way to create a new defconfig is to use the build system:
make your_defconfig
make nconfig # (de)selcet the configurations you wish to use
make savedefconfig
With that you should end up with a new defconfig.
