Download confuse-2.5.tar.gz and the libftdi1-1.4.tar.bz2 Different versions of different suffixes

Set up a working directory to move the installation package inside, unzip separately,

installation LIBFTDI into the extracted LIBFTDI Catalogue :

Execute in turn:

mkdir Build

CD Build

Then execute:

cmake-dcmake_install_prefix= "/usr". /; Make sudo make install

If the prompt is not installed CMake then execute:

sudo apt install cmake

installation CMake after the execution:

cmake-dcmake_install_prefix= "/usr". /

Make

sudo make install

Installation is complete.

installation Ftdi_eeprom ENTER after decompression confuse Directory:

Execute in turn:

./configure

Make

Make Install

The installation is complete without error

4. compiling openocd

Website Source code Installation

Download Source:

http://www.openocd.net/

copied to Ubuntu Custom Catalog

extracting a compressed package go to file directory

./configure--enable-maintainer-mode--enable-ftdi_libftdi

Make

sudo make install

Enter /usr/local/share/openocd/scripts/board Copy mini2440.cfg to the /usr/local/share/openocd/scripts

Open the file

Start by adding

#openocd 0.10.0 by default with the new FTDI interface, if you want to use the old ft2232 interface, you need to compile the Openocd when specified.

Interface Ftdi

# Specify the device by description and DMESG in the Product consistent

#ftdi_device_desc "usb<=>jtag&rs232"

# through PID VID specifying the debugger is more accurate than the description

ftdi_vid_pid 0x1457 0x5118

# If you have more than one debugger, you can also specify the debugger serial number to use

#ftdi_serial

# pin definition, equivalent to the previous version of the ft2232_layout Jtagkey

ftdi_layout_init 0x0c08 0x0f1b

ftdi_layout_signal ntrst-data 0x0100-noe 0x0400

ftdi_layout_signal nsrst-data 0x0200-noe 0x0800
