======
|
||||
The Olimex STM32-E407 configuration is based on the configuration olimex-stm32-h407 and stm32f4discovery.
|
||||
|
||||
nsh - Basic shell run on USART2.
|
||||
usbnsh - Basic shell run on the virtual serial port.
|
||||
Configurations
|
||||
==============
|
||||
|
||||
Instantiating Configurations
|
||||
----------------------------
|
||||
Each Olimex-STM32-E407 configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
tools/configure.sh olimex-stm32-e407/<subdir>
|
||||
|
||||
Where <subdir> is one of the following:
|
||||
|
||||
Compile Firmware
|
||||
----------------
|
||||
Once you've set the proper configuration, you just need to execute the next
|
||||
command:
|
||||
|
||||
make
|
||||
|
||||
If everything goes find, it should return the next two files:
|
||||
|
||||
nuttx.hex
|
||||
nuttx.bin
|
||||
|
||||
You can return more kind of files by setting on menuconfig.
|
||||
|
||||
|
||||
Flashing the Board
|
||||
-----------------
|
||||
You can flash this board in different ways, but the easiest way is using
|
||||
ARM-USB-TINY-H JTAG flasher device.
|
||||
Connect this device to the JTAG connector and type the next command:
|
||||
|
||||
openocd -f interface/ftdi/olimex-arm-usb-tiny-h.cfg -f target/stm32f4x.cfg -c init -c "reset halt" -c "flash write_image erase nuttx.bin 0x08000000"
|
||||
|
||||
Configuration Directories
|
||||
-------------------------
|
||||
nsh:
|
||||
---
|
||||
Configures the NuttShell (nsh) located at apps/examples/nsh. This
|
||||
configuration enables a console on UART2. Support for
|
||||
builtin applications is enabled, but in the base configuration no
|
||||
builtin applications are selected.
|
||||
|
||||
usbnsh:
|
||||
------
|
||||
Configures the NuttShell (nsh) located at apps/examples/nsh. This
|
||||
configuration enables a console on USB_OTG1. Support for
|
||||
builtin applications is enabled, but in the base configuration no
|
||||
builtin applications are selected.
|
||||
|
||||
netnsh:
|
||||
------
|
||||
Configures the NuttShell (nsh) located at examples/nsh. This
|
||||
configuration is focused on network testing.
|
||||
|
||||
BMP180:
|
||||
------
|
||||
This a configuration example for the BMP180 barometer sensor. This
|
||||
sensor works with I2C, you need to do the next connections:
|
||||
|
||||
BMP180 VIN -> Board 3.3V
|
||||
BMP180 GND -> Board GND
|
||||
BMP180 SCL -> Board PB6 (Arduino header D1)
|
||||
BMP180 SDA -> Board PB7 (Arduino header D0)
|
||||
|
||||
This example is configured to work with the USBNSH instead of UART NSH, so
|
||||
the console will be shown over the USB_OTG1 connector.
|
||||
|
||||
On the console, type "ls /dev " and if the registration process goes fine,
|
||||
you should see a device called "press0". Now execute the app
|
||||
BMP180 to see the ambient pressure value.
