Variables¶

Board definition¶

SOC_VENDOR

A valid value would be a directory name from ./socs (http://zrouter.org/projects/zrouter/repository/show/socs).

SOC_CHIP

A valid value would be a directory name from ./socs/${SOC_VENDOR}.

BOARD_FLASH_TYPE

Obsolete, don't use it.

BOARD_FLASH_SIZE

Physical capacity of the flash chip in bytes.

e.g. BOARD_FLASH_SIZE=4194304

Customize kernel¶

KERNCONF_IDENT

Usually ${TARGET_VENDOR}_${TARGET_DEVICE}

WITH_USB

If defined (e.g. set to WITH_USB=yes), build with kernel modules like usb, ehci, umass, etc. (see ./socs/${SOC_VENDOR}/${SOC_CHIP}/soc.mk).

KERNCONF_MODULES_OVERRIDE

Use this to append additional kernel modules, e.g. KERNCONF_MODULES_OVERRIDE+=usb/uplcom usb/u3g usb/umodem usb/ucom cam zlib

Customize world¶

WORLD_SUBDIRS_ZROUTER

?? Additional utilities, e.g. WORLD_SUBDIRS_ZROUTER+=target/sbin/upgrade

TARGET_PROFILES

TARGET_PROFILES+=SMALL_
#TARGET_PROFILES+=SMALL_ mpd ssh shttpd dlink.ua.web hostap dhcp nfs_client # mono # racoon

Firmware image options¶

FIRMWARE_IMAGE_SIZE_MAX

Image must not be bigger than kernel+rootfs partition, but other limitations can apply (e.g. GEOM_MAP_P2 upgrade partition). For example NQ-900 has 32M of RAM and 16M of flash, but it is hard to download 16M image when you have only 32M of RAM.

e.g. FIRMWARE_IMAGE_SIZE_MAX=0x007a0000

KERNEL_COMPRESSION

KERNEL_COMPRESSION=oldlzma
KERNEL_COMPRESSION_TYPE=oldlzma
UBOOT_KERNEL_COMPRESSION_TYPE=lzma
MKULZMA_BLOCKSIZE=65536

PACKING_KERNEL_IMAGE

PACKING_KERNEL_IMAGE?=kernel.kbin.oldlzma.uboot.sync

PACKING_ROOTFS_IMAGE

PACKING_ROOTFS_IMAGE?=rootfs_clean.iso.ulzma

NEW_IMAGE_TYPE

For regular u-boot image set to "ubntimage". TODO tplink

NEW_IMAGE_TYPE=ubntimage
