spi_boot_host
Description:
============
An example to drive the IO Slave on a second board.
This example acts as the boot host for spi_boot and multi_boot on Apollo
and Apollo2 MCUs. It will deliver a predefined firmware image to a boot
slave over a SPI protocol. The purpose of this demo is to show how a host
processor might store, load, and update the firmware on an Apollo or
Apollo2 device that is connected as a slave.
Please see the multi_boot README.txt for more details on how to run the
examples.
PIN fly lead connections assumed by multi_boot:
HOST SLAVE (multi_boot target)
-------- --------
GPIO[2] GPIO Interrupt (slave to host) GPIO[4] GPIO interrupt
GPIO[4] OVERRIDE pin (host to slave) GPIO[18] Override pin or n/c
GPIO[5] IOM0 SPI CLK/I2C SCL GPIO[0] IOS SPI SCK/I2C SCL
GPIO[6] IOM0 SPI MISO/I2C SDA GPIO[1] IOS SPI MISO/I2C SDA
GPIO[7] IOM0 SPI MOSI GPIO[2] IOS SPI MOSI
GPIO[11] IOM0 SPI nCE GPIO[3] IOS SPI nCE
GPIO[17] Slave reset (host to slave) Reset Pin or n/c
GND GND
Reset and Override pin connections from Host are optional
Keeping Button1 pressed on target has same effect as host driving override
