The Olimex STM32-E407 configuration is based on the configuration
|
|
|
|
|
olimex-stm32-h407 and stm32f4discovery.

Instantiating Configurations
|
|
|
|
|
----------------------------
|
|
|
|
|
Each Olimex-STM32-E407 configuration is maintained in a sub-directory and
|
|
|
|
|
can be selected as follow:
|
|
|
|
|
|
2019-07-11 10:28:42 -06:00
|
|
|
tools/configure.sh [OPTIONS] olimex-stm32-e407/<subdir>
|
2019-07-11 06:20:09 -06:00
|
|
|
|
2019-07-11 10:28:42 -06:00
|
|
|
Typical options include -l for a Linux host platform or -c for Cygwin
|
|
|
|
|
host platform. See 'tools/configure.sh -h' for other options. And
|
|
|
|
|
<subdir> is one of the sub-directories listed below.

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
|
|
|
|
|
|
2019-07-11 10:28:42 -06:00
|
|
|
You can return more kinds 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.
