approaching end of life and has not had support added for the new BF6xx and BF7xx processors. The newer toolchain is CrossCore Embedded Studio, which uses supports all Blackfin and Blackfin+ processors using upgraded versions of the same compiler and tools internally, but with a UI based on Eclipse CDT. No free version of either tool is available; a single-user license for VisualDSP++ costs $3500 USD, and CrossCore Embedded Studio $995 USD. Other options include Green Hills Software's MULTI IDE and the GNU GCC Toolchain for the Blackfin processor family. However, like VisualDSP++, these have not been updated to support the newer BF6xx and BF7xx processors. Moreover, neither support all BF5xx processors. Green Hills MULTI lacks support for BF50x, BF51x, some BF52x, BF547, and BF59x. GCC lacks support for BF50x, BF566, and BF59x, and has incomplete support for BF561. Blackfin is also supported by National Instruments' LabVIEW Embedded Module, which requires VisualDSP++. Supported operating systems, RTOSs and kernels Several commercial and open-source operating systems support running on Blackfin. Blackfin was previously supported by μClinux and later by Linux with the NOMMU feature, but as it was not ever widely used and no longer had a maintainer, support was removed from Linux on April 1, 2018; 4.16 was the last release to include Blackfin support.
