Subject: [PATCH v2 3/7] sandbox: add i2c and spi libftdi1 bit-bang example
Date: Mon, 15 Jan 2018 00:22:48 +0300 [thread overview]
Message-ID: <20180114212252.29682-4-antonynpavlov@gmail.com> (raw)
In-Reply-To: <20180114212252.29682-1-antonynpavlov@gmail.com>
Make necessary changes in sandbox_defconfig:
enable gpio, spi, i2c and led stuff.
Usage:
barebox$ make sandbox_defconfig
barebox$ sed -i "s/# CONFIG_GPIO_LIBFTDI1.*$/CONFIG_GPIO_LIBFTDI1=y/" .config
# edit arch/sandbox/dts/sandbox.dts if necessary
barebox$ make
barebox$ sudo ./barebox -d arch/sandbox/dts/sandbox.dtb
