DFU
|
||||
^^^
|
||||
|
||||
The linker files in these projects can be configured to indicate that you
|
||||
will be loading code using STMicro built-in USB Device Firmware Upgrade (DFU)
|
||||
loader or via some JTAG emulator. You can specify the DFU bootloader by
|
||||
adding the following line:
|
||||
|
||||
CONFIG_STM32_DFU=y
|
||||
|
||||
to your .config file. Most of the configurations in this directory are set
|
||||
up to use the DFU loader.
|
||||
|
||||
If CONFIG_STM32_DFU is defined, the code will not be positioned at the beginning
|
||||
of FLASH (0x08000000) but will be offset to 0x08003000. This offset is needed
|
||||
to make space for the DFU loader and 0x08003000 is where the DFU loader expects
|
||||
to find new applications at boot time. If you need to change that origin for some
|
||||
other bootloader, you will need to edit the file(s) ld.script.dfu for each
|
||||
configuration.
|
||||
|
||||
The DFU SE PC-based software is available from the STMicro website,
|
||||
http://www.st.com. General usage instructions:
|
||||
|
||||
1. Convert the NuttX Intel Hex file (nuttx.ihx) into a special DFU
|
||||
file (nuttx.dfu)... see below for details.
|
||||
2. Connect the VSN board to your computer using a USB
|
||||
cable.
|
||||
3. Start the DFU loader on the VSN board. You do this by
|
||||
resetting the board while holding the "Key" button. Windows should
|
||||
recognize that the DFU loader has been installed.
|
||||
3. Run the DFU SE program to load nutt.dfu into FLASH.
|
||||
|
||||
What if the DFU loader is not in FLASH? The loader code is available
|
||||
inside of the Demo dirctory of the USBLib ZIP file that can be downloaded
|
||||
from the STMicro Website. You can build it using RIDE (or other toolchains);
|
||||
you will need a JTAG emulator to burn it into FLASH the first time.
|
||||
|
||||
In order to use STMicro's built-in DFU loader, you will have to get
|
||||
the NuttX binary into a special format with a .dfu extension. The
|
||||
DFU SE PC_based software installation includes a file "DFU File Manager"
|
||||
conversion program that a file in Intel Hex format to the special DFU
|
||||
format. When you successfully build NuttX, you will find a file called
|
||||
nutt.ihx in the top-level directory. That is the file that you should
|
||||
provide to the DFU File Manager. You will need to rename it to nuttx.hex
|
||||
in order to find it with the DFU File Manager. You will end up with
|
||||
a file called nuttx.dfu that you can use with the STMicro DFU SE program.
|
||||
|
||||
LEDs
|
||||
^^^^
|
||||
|
||||
The VSN board has four LEDs labeled LD1, LD2, LD3 and LD4 on the
|
||||
the board. Usage of these LEDs is defined in include/board.h and src/up_leds.c.
|
||||
They are encoded as follows:
|
||||
|
||||
SYMBOL Meaning LED1* LED2 LED3 LED4
|
||||
------------------- ----------------------- ------- ------- ------- ------
|
||||
LED_STARTED NuttX has been started ON OFF OFF OFF

||||
LED_HEAPALLOCATE Heap has been allocated OFF ON OFF OFF

||||
LED_IRQSENABLED Interrupts enabled ON ON OFF OFF

LED_STACKCREATED Idle stack created OFF OFF ON OFF

LED_INIRQ In an interrupt** ON N/C N/C OFF

LED_SIGNAL In a signal handler*** N/C ON N/C OFF
|
||||
LED_ASSERTION An assertion failed ON ON N/C OFF
|
||||
LED_PANIC The system has crashed N/C N/C N/C ON
|
||||
|
||||
* If LED1, LED2, LED3 are statically on, then NuttX probably failed to boot
|
||||
and these LEDs will give you some indication of where the failure was
|
||||
** The normal state is LED3 ON and LED1 faintly glowing. This faint glow
|
||||
is because of timer interupts that result in the LED being illuminated
|
||||
on a small proportion of the time.
|
||||
*** LED2 may also flicker normally if signals are processed.
