The OpenPXA project

An Open Source boot code for Marvell PXA3xx CPUs

• Create an Open Source IPL for Marvell PXA3xx CPUs:

  CPU	Completeness	Tested steppings
  PXA300	95%	A1, A2
  PXA310	95%	A1, A2
  PXA320	95%	B2, C0

• Properly add PXA3xx support into U-Boot bootloader:

  Board	UART	SD/MMC	Ethernet	USB host	Notes	Completeness
  Toradex Colibri PXA300	YES	YES	YES	NO	--	90% *
  Toradex Colibri PXA310	YES	YES	YES	NO	--	90% *
  Toradex Colibri PXA320(IT)	YES	YES	YES	YES	--	95% *
  Marvell Littleton PXA310	YES	YES	YES	N/A	--	95% *
  Marvell Zylonite PXA300	YES	YES	YES	NO	Use MMC0 socket	90% *
  Marvell Zylonite PXA320	NO	NO	NO	NO	Problems booting	0%

  * -- The remaining 5% are there as there is always space to be better.
• Add support for PXA3xx CPUs into OpenOCD

The OpenPXA project released one public version so far. The release is called "beta", because it may contain bugs we are not yet aware of. The released files can be found on the SourceForge's file site:

• http://sourceforge.net/projects/openpxa/files/

This release contains support for Colibri PXA300, PXA310, PXA320(IT) and Littleton PXA310 boards.

• The source codes and patches are available through OpenPXA GIT [LINK]. Repository is organised like this:
  • OBM2 -- Completely rewritten bootcode. Written in C and much more modular.
  • openocd -- Patches for the OpenOCD JTAG tool. Especially the NAND code still needs some work.
  Deprecated parts of the repository:
  • OBM -- Old version of the bootcode written in assembler.
  • u-boot -- Patches for the U-Boot bootloader. Some of these are not suitable for merge into mainline yet
  
  
• To obtain sources from the OpenPXA GIT, issue the following command:

  git clone git://openpxa.git.sourceforge.net/gitroot/openpxa/openpxa

• To obtain sources from the U-Boot GIT, issue the following command:

  git clone git://git.denx.de/u-boot.git

  To obtain sources modified with OpenPXA changes, issue the following command:

  git clone git://git.denx.de/u-boot-pxa.git -b openpxa

• To obtain sources from the OpenOCD GIT, issue the following command:

  git clone git://repo.or.cz/openocd.git

NOTE: Substitute plat for your platform name and arm-crosscc- for your crosscompiler prefix.

• To compile the IPL and prepare the image header, run this from OpenPXA git root directory:

  cd OBM2
  make CROSS_COMPILE=arm-crosscc- PLAT=plat all

  This produces the ntim.bin and ipl.bin files with a small help output on how to flash those files.
   
• To compile the U-Boot bootloader, pull U-Boot sources with OpenPXA changes. Then run the following commands in U-Boot git root directory:

  make CROSS_COMPILE=arm-crosscc- clean mrproper
  make CROSS_COMPILE=arm-crosscc- plat_config
  make CROSS_COMPILE=arm-crosscc-
