![]() There is no EMMC symbol in the "enable different boot versions for the shc board" choice. SHC_EMMC was probably intended. No functional changes. Kconfig choices fall back on using the first (visible) symbol in the choice as the default if the default symbol is not visible. Discovered in Kconfiglib (https://github.com/ulfalizer/Kconfiglib), which prints the following warning: warning: the default selection EMMC (undefined) of <choice> (defined at board/bosch/shc/Kconfig:15) is not contained in the choice I've added a corresponding warning to the C tools too, which is currently in linux-next: https://patchwork.kernel.org/patch/9983667/ Signed-off-by: Ulf Magnusson <ulfalizer@gmail.com> |

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: U-Boot SPL 2016.05-rc2-00016-gf23b960-dirty (Apr 26 2016 - 09:02:18) #### NETBOOT #### SHC MPU reference clock runs at 6 MHz Setting MPU clock to 594 MHz Enabling Spread Spectrum of 18 permille for MPU Trying to boot from net Using default environment <ethaddr> not set.
