Now CONFIG_GENERIC_MMC and CONFIG_MMC match for all defconfig. We do not need two options for the same feature. Deprecate the former. This commit was generated with the sed script 's/GENERIC_MMC/MMC/' and manual fixup of drivers/mmc/Kconfig. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.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.
