2009R1.1 u-boot-2008.10 Release Notes
December 25th 2009
Highlights
- Update to upstream version 2008.10
- New SPI Flash subsystem (replaces eeprom/SPI)
- Booting Linux kernel ELF images does not pass command line (
boote) -- use bootable u-boot images instead (bootm) - POST support is broken
Build Environment
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-4.1.2)
- Build Platform: Gentoo
- Target board: BF537-STAMP and BF548-EZKIT boards
Testing is actively done with the same software on SUSE systems, but for all supported boards.
Deliverables
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.

ChangeLog
- Update to upstream version 2008.10
- disable PPI/DMA when booting Linux to avoid suspend errors when Linux does not use the PPI
- cm-bf527/cm-bf537: increase max flash sectors to cover newer boards
- increase default console size to allow people to type longer variables (like the kernel command line)
- bf527-ezkit: add example NAND boot settings
- fix vprintf/do_reset exports to standalone u-boot applications
- enable silent console support by default in ADI boards
- Blackfin TWI:
- add timeouts to all transfers instead of forcing CTRL+C
- implement bus speed get/set functions for dynamic speed changing
- fix bus clock divider calculation
- cm-bf527/cm-bf533/cm-bf537e/cm-bf548/cm-bf561/tcm-bf537:
- set default boot command to flashboot
- add better default voltage settings
- fix sector erase offset in ST Micro SPI flash driver
- pet the watchdog when doing udelay()'s
- bf533-ezkit: push out env sector to allow for larger images
- use the scratchpad when processing exceptions to avoid double faults when the stack gets a CPLB miss
- allow people to set default bootcommand when using the ADI common settings
