New Revision: https://docs.blackfin.uclinux.org/doku.php?id=toolchain:re lease-notes:2014r1 Old Revision: https://docs.blackfin.uclinux.org/doku.php?id=toolchain:re lease-notes:2014r1&rev= Edit Summary: created =====2014 Release 1 (2014R1) Toolchain Release===== Version: 2014R1 Date: March. 19, 2014 This toolchain release contains tools for three targets: bfin-elf, bfin-uc linux, and bfin-linux-uclibc. All are cross toolchains for the Blackfin ar chitecture. The bfin-elf target toolchain uses newlib for the C library an d can be used to develop standalone applications. Both of the bfin-uclinux and bfin-linux-uclibc target toolchains use uClibc for the C library and can be used to develop Linux applications. bfin-uclinux is used for the FL AT binary format while bfin-linux-uclibc is used for the ELF FD-PIC binary format. This release provides two GCC versions: 4.3.5 and 4.5.3. The Binutils vers ion in this release is 2.21. The GDB version in this release is 6.6. The u Clibc version is 0.9.33.2 and the newlib version is 1.19.0. For the 2014R1 release, there will be two separate toolchain releases. Thi s is due to upstream incompatibilities between the shared libraries of GCC -4.3 and GCC-4.5. The default release package is 2014R1-RC1 and contains G CC-4.3. A second toolchain package is available called 2014R1_45-RC1 and c ontains an experimental GCC-4.5 compiler. The former will install to the d efault directory /opt/uClinux, the latter to /opt/uClinux-45. The release is available as Linux 32-bit (i386), Linux 64-bit (x86_64) and Windows 32-bit (win32). Additionally, there are two different releases of the uClibc libraries; th e default and a “full” package, which contains a few extra features (IPV6, Wide Char, new file tree walk, netlink and ai_addrconfig support). =====Quick Selection Guide===== Under Files -> 2014R1 Select a RELEASE: 2014R1-RC1 - The default GCC 4.3 compiler 2014R1_45-RC1 - The experimental GCC 4.5 compiler Then Select a PLATFORM: i386 - Linux 32-bit x86_64 - Linux 64-bit src - Source Code blackfin-toolchain-win32-RELEASE.exe - Windows 32-bit If Selecting A Linux Release, Download: blackfin-toolchain-RELEASE.PLATFORM.{rpm/tar.bz2} - The base package For Linux (one of): blackfin-toolchain-uclibc-default-RELEASE.PLATFORM.{rpm/tar.bz2} - The d efault uClibc libraries blackfin-toolchain-uclibc-full-RELEASE.PLATFORM.{rpm/tar.bz2} - The full uClibc libraries And/Or For Bare-Metal: blackfin-toolchain-elf-gcc-{4.3/4.5}-RELEASE.PLATFORM.{rpm/tar.bz2} - Th e bare metal gcc compiler. =====Known Issues===== elf2flt passes -q option to real.ld. --gc-sections will be ignored by ld s ince it cannot be used together with -q. We do not support profiling using gprof. The latest uClibc no longer suppo rts gcc -fprofile-arcs -pg style profiling. You may use other alternatives , like OProfile. Single stepping through hardware loop does not work when there are only on e instruction in the loop. It will step over the whole loop instead. There are some incompatibilities between GCC-4.5 and GDB-6.6. Compile and link with -gdwarf-2 to limit this issue. There is a known anomaly with BF60x which can cause problems when both par ity and L1 instruction cache is enabled. There is currently no workaround available for this issue. See 16000005 - Using L1 Instruction Cache with P arity Enabled is Unreliable: http://www.analog.com/static/imported-files/ic_anom/ADSP-BF606_BF607_BF608 _BF609_anomalies_rev.B.pdf =====Changes===== * Support for bf606, bf607, bf608 and bf609, silicon revisions 0.1 and 0 .2. * Updated linux headers * gdbproxy: workaround for BF609 anomaly 16000040. * Changes to the build system and distribution packaging scripts to ensu re better compatibility. * GCC/GAS: Workaround and warning for anomaly 05000506/16000043. * PPL: Fixes for Canadian Cross compiles. |
