1Overview
2--------
3 The BSC9132 is a highly integrated device that targets the evolving
4 Microcell, Picocell, and Enterprise-Femto base station market subsegments.
5
6 The BSC9132 device combines Power Architecture e500 and DSP StarCore SC3850
7 core technologies with MAPLE-B2P baseband acceleration processing elements
8 to address the need for a high performance, low cost, integrated solution
9 that handles all required processing layers without the need for an
10 external device except for an RF transceiver or, in a Micro base station
11 configuration, a host device that handles the L3/L4 and handover between
12 sectors.
13

123Flashing Images
124---------------
125To place a new u-boot image in the NAND flash and then boot
126with that new image temporarily, use this:
127	tftp 1000000 u-boot-nand.bin
128	nand erase 0 100000
129	nand write 1000000 0 100000
130	reset
131
132Using the Device Tree Source File
133---------------------------------
134To create the DTB (Device Tree Binary) image file,
135use a command similar to this:
136
137	dtc -b 0 -f -I dts -O dtb bsc9132qds.dts > bsc9132qds.dtb
138
139Likely, that .dts file will come from here;
140
141	linux-2.6/arch/powerpc/boot/dts/bsc9132qds.dts
142
143Booting Linux
144-------------
145Place a linux uImage in the TFTP disk area.
146
147	tftp 1000000 uImage
148	tftp 2000000 rootfs.ext2.gz.uboot
149	tftp c00000 bsc9132qds.dtb
150	bootm 1000000 2000000 c00000
