Overview
|
|
--------
|
|
The BSC9132 is a highly integrated device that targets the evolving
|
|
Microcell, Picocell, and Enterprise-Femto base station market subsegments.
|
|
|
|
The BSC9132 device combines Power Architecture e500 and DSP StarCore SC3850
|
|
core technologies with MAPLE-B2P baseband acceleration processing elements
|
|
to address the need for a high performance, low cost, integrated solution
|
|
that handles all required processing layers without the need for an
|
|
external device except for an RF transceiver or, in a Micro base station
|
|
configuration, a host device that handles the L3/L4 and handover between
|
|
sectors.
|
|
|
|
The BSC9132 SoC includes the following function and features:

Flashing Images
|
|
---------------
|
|
To place a new U-Boot image in the NAND flash and then boot
|
|
with that new image temporarily, use this:
|
|
tftp 1000000 u-boot-nand.bin
|
|
nand erase 0 100000
|
|
nand write 1000000 0 100000
|
|
reset
|
|
|
|
Using the Device Tree Source File
|
|
---------------------------------
|
|
To create the DTB (Device Tree Binary) image file,
|
|
use a command similar to this:
|
|
|
|
dtc -b 0 -f -I dts -O dtb bsc9132qds.dts > bsc9132qds.dtb
|
|
|
|
Likely, that .dts file will come from here;
|
|
|
|
linux-2.6/arch/powerpc/boot/dts/bsc9132qds.dts
|
|
|
|
Booting Linux
|
|
-------------
|
|
Place a linux uImage in the TFTP disk area.
|
|
|
|
tftp 1000000 uImage
|
|
tftp 2000000 rootfs.ext2.gz.uboot
|
|
tftp c00000 bsc9132qds.dtb
|
|
bootm 1000000 2000000 c00000
