This toolchain release contains tools for three targets:
bfin-linux-uclibc. All are cross toolchains for the Blackfin architecture. The
bfin-elf target toolchain uses
newlib for the
C library and can be used to develop standalone applications. Both of the
bfin-linux-uclibc target toolchains use
uClibc for the
C library and can be used to develop
bfin-uclinux is used for the FLAT binary format while
bfin-linux-uclibc is used for the ELF FD-PIC binary format.
This release provides twp
GCC versions: 4.3.5 and 4.5.3. The
Binutils version in this release is 2.21. The
GDB version in this release is 6.6. The
uClibc version is 0.9.29 and the newlib version is 1.19.0.
For the 2011r1 release, there will be two separate toolchain releases. This is due to upstream incompatibilities between the shared libraries of GCC-4.3 and GCC-4.5. The default release package is 2011R1-RC4 and contains GCC-4.3. A second toolchain package is available called 2011R1-RC4-45 and contains an experimental GCC-4.5 compiler. The former will install to the default directory /opt/uClinux, the latter to /opt/uClinux-45.
