Prabhakar Kushwaha7530d342012-04-24 20:17:15 +0000124Flashing Images
125---------------
Bin Menga1875592016-02-05 19:30:11 -0800126To place a new U-Boot image in the NAND flash and then boot
Prabhakar Kushwaha7530d342012-04-24 20:17:15 +0000127with that new image temporarily, use this:
128 tftp 1000000 u-boot-nand.bin
129 nand erase 0 100000
130 nand write 1000000 0 100000
131 reset
132
133Using the Device Tree Source File
134---------------------------------
135To create the DTB (Device Tree Binary) image file,
136use a command similar to this:
137
138 dtc -b 0 -f -I dts -O dtb bsc9131rdb.dts > bsc9131rdb.dtb
139
140Likely, that .dts file will come from here;
141
142 linux-2.6/arch/powerpc/boot/dts/bsc9131rdb.dts
143
144Booting Linux
145-------------
146Place a linux uImage in the TFTP disk area.
147
148 tftp 1000000 uImage
149 tftp 2000000 rootfs.ext2.gz.uboot
150 tftp c00000 bsc9131rdb.dtb
