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

Testing is 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.
