      3           m3dev - tools for embedded ARM Cortex M3 development
      4 ===========================================================================

      6 This project is a collection of (linux-centric) tools for working on
      7 small embedded systems based on the ARM Cortex M3 CPU.
      8 
      9 Original work was done with a STM32F103 part, and much more work has been
     10 done with LPC13xx series parts.
     11 
     12 Everything is either Apache 2 or BSD licensed, to allow for easy,
     13 no-strings-attached, inclusion in your own projects.  Share and enjoy!

     16 m3debug
     17 -------
     18 
     19 Firmware for the "m3debug" and "super-m3debug" boards which use the
     20 LPC1343 as an engine for the ARM Serial Wire Debug Protocol, in 
     21 conjunction with the debugger and gdb-bridge programs (described
     22 below).
     23 
     24 A schematic is provided for the original (pretty simplistic) m3debug
     25 board.
     26 
     27 
     28 swdp 
     29 ----
     30 
     31 Firmware for the LeafLabs Maple board to act as a USB<->SW-DP bridge,
     32 to allow host software to use Serial Wire Debug Protocol to access target
     33 devices.  It should be usable on just about any STM32F103 board.
     34 
     35 GPIO 0 -> SWDIO
     36 GPIO 1 -> SWCLK
     37 GPIO 5 -> Activity LED
     38 
     39 This was the original prototype and has not been tested in a looong
     40 time now.
     41 
     42 
     43 debugger & gdb-bridge
     44 ---------------------
     45 
     46 A simple standalone debugger and a bridge for the GDB remote protocol
     47 that commicate with a board running swdp.
     48 
     49 
     50 stm32boot
     51 ---------
     52 
     53 A tool to download code to RAM or flash, via the stm32f1xx ROM serial
     54 bootloader.
     55 
     56 
     57 usbmon
     58 ------
     59 
     60 Commandline tool to observe the linux usb stack and io transactions
     61 through /dev/usbmon*
     62 
     63 
     64 Included Third Party Software
     65 -----------------------------
     66 
     67 linenoise.[ch] 
     68   excellent tiny commandline editor (BSD license)
     69   https://github.com/antirez/linenoise
     70 
     71 
     72 Useful Documents
     73 ----------------
     74 
     75 ARM DDI0337E Cortex M3 r1p1 Technical Reference Manual
     76   Has useful details on SW-DP and debug peripherals that was removed
     77   in later versions of the TRM as "redundant" with other documents.
     78 
     79 
     80 Historical Notes
     81 ----------------
     82 
     83 The original work on this started in 2011 and has been tinkered with
     84 on a number of repositories by a number of people.  Trying to fold things
     85 back together and tidy up the build system, etc, ended up being a bit of
     86 a mess resulting in Brian declaring "history bankruptcy" and starting
     87 a fresh repository in 2014.
     88 
     89 Some random side projects have been removed.  An AUTHORS file has been
     90 added to provide credit for additional contributors to the codebase.
     91 
     92 The code base as of the initial checkin, built with gcc 4.8.2 and
     93 binutils 2.24 (http://github.com/travisg/toolchains) is verified to
     94 be able to use a m3debug board to flash the bootloader and app image
     95 to another m3debug board, which then can repeat the process.
