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
|
