This repositary contents code for initial program loader (bootstrap), placed
in first sector of NAND Flash Toradex Colibri PXA320. This is startup (reset
vector) code used for load real bootloader, like U-Boot. You may write them
into NAND flash memory via Toradex Colibri Loader software (via JTAG interface
only). Please NOT build and upgrade Colibri Modules by any other ways.
Build instruction for Gentoo users:
- prepare toolchain:
# emerge crossdev
# crossdev --stabe --target armv5tel-softfloat-linux-gnueabi
or
# crossdev --stabe --target armv5te-iwmmxt-linux-gnueabi
- clone bootstrap code and switch to ravion tree
# git clone git://github.com/MinimumLaw/ravion-pxa-bootstrap.git
# cd ravion-pxa-bootstrap
# git checkout obm2-ravion
or update existing repsitary clone
- build bootstrap code
# make CROSS_COMPILE=armv5tel-softfloat-linux-gnueabi- PLAT=colibri_pxa320
or
# make CROSS_COMPILE=armv5te-iwmmxt-linux-gnueabi- PLAT=colibri_pxa320
you must copy compiled iplntim.bin - this is ready to use bootstrap code
- prepare WinCE binary image (require for flashing)
Reboot into Microsof Windows
Got CreateTBin utility from Toradex support website
http://files.toradex.com/Colibri/WinCE/Special/CreateTBin/
# CreateTBIN.exe -a 0 -j iplntim.bin
you got iplntim_TBin.bin - boostrap code packed into WinCE binary image
- Flash bootstrap code into Colibri Module
Got ColibriLoader from Toradex support website

Flash image into module

1. Module with bad bootstrap code will be bricked! For unbrick module reflash
them with bootstrap code or WinCE bootloader image from Toradex support web
site http://files.toradex.com/Colibri/WinCE/Images/ via JTAG interface.
2. Module with only bootstrap code in NAND flash will be half-bricked. Second
stage bootloader MUST be flashed into NAND flash on proper address (offset).
For unbrick flash U-Boot code (for OAO Radioavionica patches offset 0x60000)
with CreateTBIN/ColibriLoader via JTAG or reflash module with WinCE as write
in http://files.toradex.com/Colibri/WinCE/ColibriLoader/ColibriLoader.txt
Flash bootloader via JTAG and Image via ethernet connection.
