2011R1 u-boot-2011.09 Release Notes

November 23rd 2011

• Update to upstream version 2011.09
• Legacy boards that is tested in this release
  • BF518F-EZBRD
  • BF526-EZBRD
  • BF527-EZKIT
  • BF533-STAMP
  • BF533-EZKIT
  • BF537-STAMP
  • BF548-EZKIT
  • BF561-EZKIT
• New processor support
  • BF504/BF506
• New board support
  • bf506f-ezkit
  • bf525-ucr2
  • bf527-sdp
  • bct-brettl2
  • blackvme
  • dnp5370
• All “p” style MMR defines are removed (*pMMR = 0;) -- use bfin_{read,write}_MMR() instead
• NAND is initialized at first use, not always during boot
• go no longer implicitly disables caches
• POST support is working

While we would love to test every environment out there that you may use, we'll document the platforms we actively develop and test on. Refer to the documentation for setting up your system.

Development is actively done with:

• Toolchain: Blackfin Toolchain (GCC-4.3.5)
• Build Platform: Gentoo
• Target board: BF537-STAMP and BF548-EZKIT boards

Released u-boot tar ball posted on our website and testing are both actively done with the same software on SUSE systems, but for all supported boards.

File names generally take the form u-boot-<board>-<boot mode>-<version>.filetype.

Each board has one tarball which contains all of the release images for that board. For information on which file to use, see the binaries and boot modes pages. Additionally, a u-boot.elf and init.elf file are included to facilitate booting via JTAG.

All files are raw binary. That means you use them as is. They are most certainly not in the hex or srec format. Alternative file formats are no longer provided as part of the release. If you really need such a file, you will need to convert it yourself.
