OpenOCD

OpenOCD has been in a pretty steady state of flux. For now just grab the current SVN:

$ svn checkout svn://svn.berlios.de/openocd/trunk

Before you can configure you have to run:

$ ./bootstrap

Configure it:

$ ./configure --enable-ft2232_libftdi --enable-maintainer-mode

Make it:

$ make

Install it:

# make install

Initialize openocd:

# openocd -f interface/signalyzer.cfg -f board/imx27som.cfg

Open connection to OpenOCD

$ telnet localhost 4444

Redboot

Redboot is based on ecos. A good starting point is here First pull the installer

$ wget --passive-ftp ftp://ecos.sourceware.org/pub/ecos/ecos-install.tcl

Then run it, be sure to include the arm-elf tools as that's what the freescale version wants.

$ ./ecos-install.tcl

It wants to run ecosenv.sh so set up the environment correctly. It says to stick it in .profile or .login. I think .bashrc will also work. Install old compat-libstdc

# yum install compat-libstdc++-3

Freescale has a version of ecos that they have patched to work with the imx27. First you need to download redboot_200719.tar.gz, that has both the base as well as the patches. to convert all the dos files to unix files use:

$ find . -type f -exec dos2unix {} \;

Then you can patch the tree:

$  bunzip2 -c ../patch-redboot-200719-base.bz2 | patch -p1
$  bunzip2 -c ../patch-redboot-200719-mx27.bz2 | patch -p1

Next set the ECOS_REPOSITORY environment variable:

$ export ECOS_REPOSITORY=/path_to_redboot/redboot_200719/src/ecos_20050912/packages/

Configure for imx27

$ ecosconfig new mx27ads redboot
$ ecosconfig import $ECOS_REPOSITORY/hal/arm/mx27/ads/current/misc/redboot_ROMRAM.ecm
$ ecosconfig tree

And finally make:

$ make

Now you should have redboot.bin under install/bin
