7.4 BSP Build Requirements
Build Host
The Basic Support Package (BSP) is hosted by an x86 computer running Linux. At least 1 GB free
space is required where the BSP is hosted.
Build Tools
Artesyn is using build tools provided in Freescale SDK1.0 QorIQ-DPAA-SDK-20110609-
systembuilder.iso to build BSP images for SCP-P4080-2G-ENP2.
printenv [vn] Displays the value of the environment variable "vn".
If "vn" is not specified, U-Boot will display the values for all of the envi-
ronment variables.
setenv <vn> [vv] Sets the value of the environment variable "vn" to "vv". If "vv" is not spec-
ified, U-Boot will not define the environment variable "vn".
If "vv" includes spaces, it should be enclosed within single quote marks.
For example:
setenv manufacturer ’Emerson Network
Power’
saveenv Saves all the environment variables persistently to the U-Boot env sec-
tion on NOR Flash.
run eraenv Erases all the environment variables stored in the U-Boot env section on
NOR Flash.
