2.5 Test On STM32F767ZI - Blinky
Finally, we come to test out some examples on board Nucleo-144 STM32F767ZI.

2.5.1 Plug in Nucleo-144 STM32F767ZI

We first plug in the board Nucleo-144 STM32F767ZI as follows:
STM32F767ZI STLink - 2 USB Ports
  • On one side, plugging in the STLink USB port with the host computer is demonstrated by command lsusb.
$ lsusb
...
Bus 001 Device 005: ID 0483:374b STMicroelectronics ST-LINK/V2.1 (Nucleo-F103RB)
...
If we had ST-Link successfully installed, we can also demonstrate its existance by command st-info --probe.
$ st-info --probe
Found 1 stlink programmers
serial: 303636454646333333303336343334
openocd: "\x30\x36\x36\x45\x46\x46\x33\x33\x33\x30\x33\x36\x34\x33\x34"
flash: 2097152 (pagesize: 2048)
sram: 524288
chipid: 0x0451
descr: F76xxx device
  • On the other side, plugging in the other USB port for Nucleo-144 STM32F767ZI will be demonstrated by our test code.

2.5.2 Create and Build Project

Similar to previous section, this time, we create a Blinky C/C++ project with board configuration STM32F7xx with Chip family STM32F767xx. And we can also have the project successfully built with Release configuration with the following output:
17:57:31 **** Build of configuration Release for project F767ZI_Blinky ****

2.5.3 Flash Built .elf onto Nucleo-144 STM32F767ZI

As we mentioned in previous section, the NEWEST GNU MCU Eclipse QEMU does NOT support Nucleo-144 STM32F767ZI yet. Therefore, we are going to flash F767ZI_Blinky.elf directly onto Nucleo-144 STM32F767ZI for our test.
We first have a look at how many ST tools have been installed:
$ ls -ls /usr/local/bin/st*
16 -rwxr-xr-x 1 root root 14312 May 18 23:16 /usr/local/bin/st-flash
12 -rwxr-xr-x 1 root root 10216 May 18 23:16 /usr/local/bin/st-info
104 -rwxr-xr-x 1 root root 104960 May 18 23:16 /usr/local/bin/stlink-gui
52 -rwxr-xr-x 1 root root 51544 May 18 23:16 /usr/local/bin/st-util
And, let's try out each ST tool one by one.

st-info

Tested in the above already, and its ONLY usage is:
$ st-info --probe
Found 1 stlink programmers
serial: 303636454646333333303336343334
openocd: "\x30\x36\x36\x45\x46\x46\x33\x33\x33\x30\x33\x36\x34\x33\x34"
flash: 2097152 (pagesize: 2048)
sram: 524288
chipid: 0x0451
descr: F76xxx device

st-util

Let's have a look at how can we use st-util by help.
$ st-util --help
st-util - usage:
-h, --help Print this help
-V, --version Print the version
-vXX, --verbose=XX Specify a specific verbosity level (0..99)
-v, --verbose Specify generally verbose logging
-s X, --stlink_version=X
Choose what version of stlink to use, (defaults to 2)
-1, --stlinkv1 Force stlink version 1
-p 4242, --listen_port=1234
Set the gdb server listen port. (default port: 4242)
-m, --multi
Set gdb server to extended mode.
st-util will continue listening for connections after disconnect.
-n, --no-reset
Do not reset board on connection.
--semihosting
Enable semihosting support.
--serial <serial>
Use a specific serial number.
The STLINKv2 device to use can be specified in the environment
variable STLINK_DEVICE on the format <USB_BUS>:<USB_ADDR>.
Then, we print out the version as:
$ st-util -V
st-util: invalid option -- 'V'
st-util 1.4.0-37-g065a475

Command stlink-gui will pop up a dialog automatically:
STLink Gui Initialization
Then we click on the Connect button:
STLink Gui Connecting with Board
After a while, we can see the data in tab Device Memory after the device is connected:
STLink Gui Connected
Then we click on No file and load the built .elf file F767ZI_Blinky.elf:
STLink Gui Load F767ZI_Blinky.elf
After loading F767ZI_Blinky.elf, we can see the data in tab F767ZI_Blinky.elf:
STLink Gui F767ZI_Blinky.elf Loaded
And now it's the time to flash the loaded file F767ZI_Blinky.elf down to board Nucleo-144 STM32F767ZI:
STLink Gui Flash F767ZI_Blinky.elf to Device
Flashing
STLink Gui Flashing
We also notice the situation change from within bash as follows:
$ Gtk-Message: 18:40:02.578: GtkDialog mapped without a transient parent. This is discouraged.

After finishing flashing the data onto the device, we can even Export device memory into a particular file. Here, we can see, the data is successfully exported.
STLink Gui Flash F767ZI_Blinky.elf to Device
Finally, we can disconnect the device after flashing.
STLink Gui Disconnected
Clearly, stlink-gui is a GUI application to flash built .elf down to the device (a development board with some particular MCU).

st-flash

Unlike stlink-gui, st-flash is a command line application to flash built .bin down to the embedded device. But, we need firstly build .bin file out from .elf file. Here, we need to use the command arm-none-eabi-objcopy.
$ arm-none-eabi-objcopy -S -O binary F767ZI_Blinky.elf F767ZI_Blinky.bin
Afterwards, we investigate how to use st-flash :
$ st-flash --help
invalid command line
stlinkv1 command line: ./st-flash [--debug] [--reset] [--format <format>] [--flash=<fsize>] {read|write} /dev/sgX <path> <addr> <size>

stlinkv2 command line: ./st-flash [--debug] [--reset] [--serial <serial>] [--format <format>] [--flash=<fsize>] {read|write} <path> <addr> <size>
stlinkv2 command line: ./st-flash [--debug] [--serial <serial>] erase
stlinkv2 command line: ./st-flash [--debug] [--serial <serial>] reset
Use hex format for addr, <serial> and <size>.
fsize: Use decimal, octal or hex by prefix 0xXXX for hex, optionally followed by k=KB, or m=MB (eg. --flash=128k)
Format may be 'binary' (default) or 'ihex', although <addr> must be specified for binary format only.
./st-flash [--version]
We can also refer to st-flash documentation for more details.
Usage 1: Flash .bin file to device
$ st-flash write firmware.bin 0x8000000
Usage 2: Read .bin from device (4096 bytes)
$ st-flash read firmware.bin 0x8000000 4096
Erase firmware from device
$ st-flash erase

Step 1: Erase Memory on Device

$ st-flash erase

We then listen to the port 4242 specified in st-util.

Tab 2:

Then, we load the data from gdb.

Tab 2:

(gdb) load

Afterward, we continue in gdb.

Tab 2:

(gdb) continue
