Ubuntu環境下使用stlink除錯和下載stm32f4-discovery程式

原創,轉載標明出處

首先下載stlink的Linux版本,下載地址

然後解壓到你所指定的路徑下,參照其中的README檔案進行編譯配置。如下:(筆者在此將對關鍵點進行標註)

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.

Common requirements
(依賴環境) ~~~~~~~~~~~~~~~~~~~ . libusb-1.0 (You probably already have this, but you'll need the development version to compile)
(這個工具只需要執行sudo apt-get install libusb-dev && sudo apt-get install libusb-1.0-0-dev這兩個命令即可。)
. pkg-config(這個工具一般Ubuntu都會預設安裝,注意變數PKG-CONFIG-PATH的設定)
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
(我們的開發板支援STLINKv2,所以這裡不做配置) ~~~~~~~~~~~~~~~~~~~~~~~ You're ready to go :) COMPILING(編譯:下邊3個指令即可) ~~~~~~~~~ This project was converted to Autotools by a well meaning individual. The following steps will build the project for you. $ ./autogen.sh $ ./configure $ make USING THE GDBSERVER(使用GDB除錯服務) ~~~~~~~~~~~~~~~~~~~ To run the gdb server: (you do not need sudo if you have set up permissions correctly)
(此時連上你的開發板,一般都要sudo)$ 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 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) (重新開啟一個終端,找到你編譯好的應用程式的目錄,就是存在elf檔案的地方)$ arm-none-eabi-gdb fancyblink.elf (開啟除錯) ... (gdb) tar extended-remote :4242 (連上GDB服務) ... (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 Have fun! 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. 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(在RAM上執行) ========================== 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(燒寫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'.
