+
+## 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 2 versions:
-. STLINKv1, present on STM32VL discovery kits,
-. STLINKv2, present on STM32L discovery and later kits.
-2 different transport layers are used:
-. STLINKv1 uses SCSI passthru commands over USB,
-. STLINKv2 uses raw USB commands.

+* STLINKv2, present on STM32L discovery and later kits.
+
+Two different transport layers are used:
-Common requirements
-~~~~~~~~~~~~~~~~~~~
+* STLINKv1 uses SCSI passthru commands over USB
+* STLINKv2 uses raw USB commands.
-. libusb-1.0 (You probably already have this, but you'll need the
-development version to compile)
-. pkg-config
+## Common requirements
+
+* `pkg-config`
+* `libusb-1.0` (plus development headers for building, on debian based distros `libusb-1.0.0-dev` package)
+
+## For STLINKv1
-IF YOU HAVE AN STLINKv1
-~~~~~~~~~~~~~~~~~~~~~~~
The STLINKv1's SCSI emulation is very broken, so the best thing to do
is tell your operating system to completely ignore it.
Options (do one of these before you plug it in)
- *) modprobe -r usb-storage && modprobe usb-storage quirks=483:3744:i
-or *)1. add "options usb-storage quirks=483:3744:i" to /etc/modprobe.conf
- *)2. modprobe -r usb-storage && modprobe usb-storage
-or *)1. cp stlink_v1.modprobe.conf /etc/modprobe.d
- *)2. modprobe -r usb-storage && modprobe usb-storage
-IF YOU HAVE AN STLINKv2
-~~~~~~~~~~~~~~~~~~~~~~~
+* `modprobe -r usb-storage && modprobe usb-storage quirks=483:3744:i`
+* or 1. `echo "options usb-storage quirks=483:3744:i" >> /etc/modprobe.conf`
+* 2. `modprobe -r usb-storage && modprobe usb-storage`
+* or 1. `cp stlink_v1.modprobe.conf /etc/modprobe.d`
+* 2. `modprobe -r usb-storage && modprobe usb-storage`
+
+## For STLINKv2
You're ready to go :)
-COMPILING
-~~~~~~~~~
+## Build from sources
+
+### Autotools
+
This project was converted to Autotools by a well meaning individual. The
following steps will build the project for you.
+```
$ ./autogen.sh
$ ./configure
$ make
+```
+
+### CMake
+
+```
+$ mkdir build && cd build
+$ cmake -DCMAKE_BUILD_TYPE=Debug ..
+$ make
+```
+
+## Using the gdb server
-USING THE GDBSERVER
-~~~~~~~~~~~~~~~~~~~
To run the gdb server: (you do not need sudo if you have set up
permissions correctly)
+```
$ make && [sudo] ./st-util
There are a few options:
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 on the format <USB_BUS>:<USB_ADDR>.
+variable STLINK_DEVICE on 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)
...
(gdb) continue
+```
Have fun!
-Resetting the chip from GDB
-===========================
+## 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
+Starting program: /home/whitequark/ST/apps/bally/firmware.elf
+```
Remember that you can shorten the commands. `tar ext :4242' is good enough
for GDB.
-Setting up udev rules
-=====================
+## Setting up udev rules
For convenience, you may install udev rules file, 49-stlinkv*.rules, located
in the root of repository. You will need to copy it to /etc/udev/rules.d,
and then either reboot or execute
+
+```
$ udevadm control --reload-rules
$ udevadm trigger
+```
Udev will now create a /dev/stlinkv2_XX or /dev/stlinkv1_XX file, with the appropriate permissions.
This is currently all the device is for, (only one stlink of each version is supported at
any time presently)
-Running programs from SRAM
-==========================
+## 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
-================
+## 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
then it would be written to the memory.
-FAQ
-===
+## FAQ
Q: My breakpoints do not work at all or only work once.
it will use a rather inefficient single-stepping way of doing that.
Set up a breakpoint manually in that case and do `continue'.
-Currently known working combinations of programmer and target
-=============================================================
+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.
