Build Status

CMSIS-DAP programmer

This is a simple command line utility for programming ARM-based MCUs through CMSIS-DAP SWD interface. It works on Linux, Mac OS X and Windows. It was tested with Atmel mEDBG- and EDBG-based boards, Atmel-ICE, LPC-Link2, IBDAP and Free-DAP-based debuggers.

Installation

Binary releases can be downloaded from here. Binary releases are not tested, they are a result of automated build process. Please report if you see any issues with them.

If you want to build from the source code, simply run make all and you will get a small binary, called edbg.

Dependencies

The dependencies are minimal. In addition to normal development tools (GCC, make, etc) you will need:

  • Windows: none
  • Linux: libudev-dev
  • Mac OS X: libhidapi (can be installed via brew)

Usage

Usage: edbg [options]
Options:
  -h, --help                 print this help message and exit
  -b, --verbose              print verbose messages
  -x, --reset <duration>     assert the reset pin before any other operation (duration in ms)
  -e, --erase                perform a chip erase before programming
  -p, --program              program the chip
  -v, --verify               verify memory
  -k, --lock                 lock the chip (set security bit)
  -u, --unlock               unlock the chip (forces chip erase in most cases)
  -r, --read                 read the whole content of the chip flash
  -f, --file <file>          binary file to be programmed or verified; also read output file name
  -t, --target <name>        specify a target type (use '-t list' for a list of supported target types)
  -l, --list                 list all available debuggers
  -s, --serial <number>      use a debugger with a specified serial number
  -c, --clock <freq>         interface clock frequency in kHz (default 16000)
  -o, --offset <offset>      offset for the operation
  -z, --size <size>          size for the operation
  -F, --fuse <options>       operations on the fuses (use '-F help' for details)
Fuse operations format: <actions><section>,<index/range>,<value>
  <actions>     - any combination of 'r' (read), 'w' (write), 'v' (verify)
  <section>     - index of the fuse section, may be omitted if device has only
                  one section; use '-h -t <target>' for more information
  <index/range> - index of the fuse, or a range of fuses (limits separated by ':')
                  specify ':' to read all fuses
                  specify '*' to read and write values from a file
  <value>       - fuses value or file name for write and verify operations
                  immediate values must be 32 bits or less

Multiple operations may be specified in the same command. They must be separated with a ';'.

Exact fuse bits locations and values are target-dependent.

Examples

>edbg -b -t samd11 -pv -f build/Demo.bin
Debugger: ATMEL EDBG CMSIS-DAP ATML2178031800000312 01.1A.00FB (S)
Clock frequency: 16.0 MHz
Target: SAM D11D14A (Rev B)
Programming............................................... done.
Verification............................................... done.

Fuse operations:

  -F w,1,1             -- set fuse bit 1
  -F w,8:7,0           -- clear fuse bits 8 and 7
  -F v,31:0,0x12345678 -- verify that fuse bits 31-0 are equal to 0x12345678
  -F wv,5,1            -- set and verify fuse bit 5
  -F r1,:,             -- read all fuses in a section 1
  -F wv,*,fuses.bin    -- write and verify all fuses from a file
  -F w0,1,1;w1,5,0     -- set fuse bit 1 in section 0 and clear fuse bit 5 in section 1
