+Summary
+=======
+
+This document covers various features of the 'am335x_shc' build.
+
+Hardware
+========
+
+AM335X based board:
+
+I2C: ready
+DRAM: 512 MiB
+Enabling the D-Cache
+MMC: OMAP SD/MMC: 0 @ 26 MHz, OMAP SD/MMC: 1 @ 26 MHz
+Net: cpsw
+
+Following boot options are possible:
+
+2 Jumpers:
+
+Jumper 1 Jumper 2 Bootmode
+off off eMMC boot
+on off SD boot
+off on Net boot
+
+Compiling
+=========
+
+$ make am335x_shc_defconfig
+ HOSTCC scripts/basic/fixdep
+ HOSTCC scripts/kconfig/conf.o
+ SHIPPED scripts/kconfig/zconf.tab.c
+ SHIPPED scripts/kconfig/zconf.lex.c
+ SHIPPED scripts/kconfig/zconf.hash.c
+ HOSTCC scripts/kconfig/zconf.tab.o
+ HOSTLD scripts/kconfig/conf
+#
+# configuration written to .config
+#
+$ make -s all
+
+-> now you have the MLO and the u-boot.img file, you can put
+on your SD card or eMMC.
+
+Configuring
+===========
+
+There are a lot of board versions and boot configurations, which
+can be selected through "make menuconfig"
+
+ARM architecture --->
+ enable different boot versions for the shc board (enable eMMC) --->
+ (X) enable eMMC
+ ( ) enable ICT
+ ( ) enable NETBOOT
+ ( ) enable SDBOOT
+
+ enable different board versions for the shc board (C3 Sample board version) --->
+ ( ) B Sample board version
+ ( ) B2 Sample board version
+ ( ) C Sample board version
+ ( ) C2 Sample board version
+ (X) C3 Sample board version
+ ( ) Series board version
+
+Netboot
+=======
+- see also doc/SPL/README.am335x-network
+
+- set the jumper into netboot mode
+- compile the U-boot sources with:
+ make am335x_shc_netboot_defconfig
+ make all
+- copy the images into your tftp boot directory
+ cp spl/u-boot-spl.bin /tftpboot/.../u-boot-spl-restore.bin
+ cp u-boot.img /tftpboot/.../u-boot-restore.img
+- power on the board, and you should get something like this:
