## Introduction
This stlink toolset supports several so called stlink programmer boards (and clones thereof) which use a microcontroller chip to translate commands from USB to JTAG.
STLink is an open source toolset to program and debug STM32 devices and boards manufactured by STMicroelectronics.
It supports several so called STLINK programmer boards (and clones thereof) which use a microcontroller chip
to translate commands from USB to JTAG/SWD. There are four generations available on the market:
These programmer boards are available in four versions:
* **STLINKv1:**
* **STLINK/v1** _(obsolete as of 21-11-2019)_
- transport layer: SCSI passthru commands over USB
- present on STM32VL discovery kits
* **STLINKv2:**
* transport layer: raw USB commands
* present on STM32L discovery and nucleo and later kits
* **STLINKv2-1:**
* transport layer: raw USB commands
* present on some STM32 nucleo boards
* **STLINKv3:**
* _not yet supported by this toolset (but planned)_
- stand-alone programmer and present on STM32VL Discovery boards
* **STLINK/v2**
- transport layer: raw USB commands
- stand-alone programmer and present on STM32L Discovery and Nucleo boards
* **STLINK/v2-1**
- transport layer: raw USB commands
- present on some STM32 Nucleo boards
* **STLINK/v3**
- transport layer: raw USB commands
- stand-alone programmer
On the user level there is no difference in handling or operation between these different revisions.
The STlink toolset includes:
* a communication library (libstlink.a),
* a programmer and chip information tool (st-info),
* a flash manipulation tool (st-flash),
* a GDB server (st-util) and
* a GUI-Interface (stlink-gui) _[optional]_

#### Checksum for binary files
When flashing a file, a checksum is calculated for the binary file, both in md5 and the sum algorithm.
The latter is also used by the official ST-Link utility tool from STMicroelectronics as described in the document: [`UM0892 - User manual - STM32 ST-LINK utility software description`](https://www.st.com/resource/en/user_manual/cd00262073-stm32-stlink-utility-software-description-stmicroelectronics.pdf).

Installing STLINK
=================
STLINK is open source software to program and debug ST’s STM32 Discovery
kits. Those kits have an onboard chip that translates USB commands sent
by the host PC into JTAG/SWD commands. This chip is called STLINK, (yes,
isn’t that confusing? suggest a better name!) and comes in 2 versions
(STLINK v1 and v2). From a software point of view, those versions differ
only in the transport layer used to communicate (v1 uses SCSI passthru
commands, while v2 uses raw USB). From a user point of view, they are
identical.
Before continuing, the following dependencies must be met:
- libusb-1.0
- cmake
Also make sure `gtk+` version 3.0 is installed. (`sudo apt-get install gtk+-3.0` or similiar)
STLINK should run on any system meeting the above constraints.
The STLINK software source code is retrieved using:
```
$> git clone https://github.com/texane/stlink.git
```
Everything can be built from the top directory:
```
$> cd stlink
$> make
$> cd build/Release && make install DESTDIR=_install
```
It includes:
- a communication library (libstlink.a),
- a GDB server (st-util),
- a flash manipulation tool (st-flash).
- a programmer and chip information tool (st-info)

Notes
=====
Disassembling THUMB code in GDB
-------------------------------
By default, the disassemble command in GDB operates in ARM mode. The
programs running on CORTEX-M3 are compiled in THUMB mode. To correctly
disassemble them under GDB, uses an odd address. For instance, if you
want to disassemble the code at 0x20000000, use:\
```
(gdb) disassemble 0x20000001
```
Checksum of binary file
-----------------------
When flashing a file, the checksum of which is calculated, both in md5 and the sum algorithm used by ST's official tool. The detail of sum algorithm can be found in [https://www.st.com/resource/en/user_manual/cd00262073-stm32-stlink-utility-software-description-stmicroelectronics.pdf](https://www.st.com/resource/en/user_manual/cd00262073-stm32-stlink-utility-software-description-stmicroelectronics.pdf).
