Open source version of the STMicroelectronics Stlink Tools
HOWTO
First, you have to know there are several boards supported by the software. Those boards use a chip to translate from USB to JTAG commands. The chip is called stlink and there are two versions:
- STLINKv1, present on STM32VL discovery kits,
- STLINKv2, present on STM32L discovery and later kits.
Two different transport layers are used:
- STLINKv1 uses SCSI passthru commands over USB
- STLINKv2 and STLINKv2-1 (seen on nucleo boards) uses raw USB commands.
Installation
Windows users can download v1.3.0 from the releases page.
Mac OS X users can install from homebrew or download v1.3.0 from the releases page.
For Debian Linux based distributions there is no package available in the standard repositories so you need to install from source yourself.
Arch Linux users can install from the repository
Alpine Linux users can install from the repository
Fedora users can install from repository
RedHat/CentOS 7 users can install from EPEL repository
Gentoo Linux users can install from the official portage repository
FreeBSD users can install from freshports
OpenBSD users need to install from source.
Installation from source (advanced users)
When there is no executable available for your platform or you need the latest (possible unstable) version you need to compile yourself. This is explained in the compiling manual.
Using the gdb server
To run the gdb server:
$ make && [sudo] ./st-util
There are a few options:
./st-util - usage:
-h, --help Print this help
-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.
The STLINKv2 device to use can be specified in the environment
variable STLINK_DEVICE
in the format <USB_BUS>:<USB_ADDR>
.
Then, in your project directory, someting like this... (remember, you need to run an ARM gdb, not an x86 gdb)
$ arm-none-eabi-gdb fancyblink.elf
...
(gdb) tar extended-remote :4242
...
(gdb) load
Loading section .text, size 0x458 lma 0x8000000
Loading section .data, size 0x8 lma 0x8000458
Start address 0x80001c1, load size 1120
Transfer rate: 1 KB/sec, 560 bytes/write.
(gdb)
...
(gdb) continue
Resetting the chip from GDB
You may reset the chip using GDB if you want. You'll need to use `target extended-remote' command like in this session:
(gdb) target extended-remote localhost:4242
Remote debugging using localhost:4242
0x080007a8 in _startup ()
(gdb) kill
Kill the program being debugged? (y or n) y
(gdb) run
Starting program: /home/whitequark/ST/apps/bally/firmware.elf
Remember that you can shorten the commands. `tar ext :4242' is good enough for GDB.
Running programs from SRAM
You can run your firmware directly from SRAM if you want to. Just link it at 0x20000000 and do
(gdb) load firmware.elf
It will be loaded, and pc will be adjusted to point to start of the code, if it is linked correctly (i.e. ELF has correct entry point).
Writing to flash
The GDB stub ships with a correct memory map, including the flash area.
If you would link your executable to 0x08000000
and then do
(gdb) load firmware.elf
then it would be written to the memory.
FAQ
Q: My breakpoints do not work at all or only work once.
A: Optimizations can cause severe instruction reordering. For example, if you are doing something like `REG = 0x100;' in a loop, the code may be split into two parts: loading 0x100 into some intermediate register and moving that value to REG. When you set up a breakpoint, GDB will hook to the first instruction, which may be called only once if there are enough unused registers. In my experience, -O3 causes that frequently.
Q: At some point I use GDB command `next', and it hangs.
A: Sometimes when you will try to use GDB next
command to skip a loop,
it will use a rather inefficient single-stepping way of doing that.
Set up a breakpoint manually in that case and do continue
.
Q: Load command does not work in GDB.
A: Some people report XML/EXPAT is not enabled by default when compiling GDB. Memory map parsing thus fail. Use --enable-expat.

Known bugs
Sometimes flashing only works after a mass erase
There is seen a problem sometimes where a flash loader run error occurs and is resolved after mass-erase of the flash:
2015-12-09T22:01:57 INFO src/stlink-common.c: Successfully loaded flash loader in sram
2015-12-09T22:02:18 ERROR src/stlink-common.c: flash loader run error
2015-12-09T22:02:18 ERROR src/stlink-common.c: run_flash_loader(0x8000000) failed! == -1
Issue related to this bug: #356
Flash size is detected as zero bytes size
It is possible that the STM32 flash is write protected, the st-flash tool will show something like this:
st-flash write prog.bin 0x8000000
2017-01-24T18:44:14 INFO src/stlink-common.c: Loading device parameters....
2017-01-24T18:44:14 INFO src/stlink-common.c: Device connected is: F1 High-density device, id 0x10036414
2017-01-24T18:44:14 INFO src/stlink-common.c: SRAM size: 0x10000 bytes (64 KiB), Flash: 0 bytes (0 KiB) in pages of 2048 bytes
As you can see, it gives out something unexpected like
Flash: 0 bytes (0 KiB) in pages of 2048 bytes
st-info --probe

Try to remove the write protection (probably only possible with ST Link Utility from ST itself).
