For the past 14 years Analog Devices has developed and maintained the ports of uCLinux, uBoot, GCC, GDB and Buildroot for the Blackfin BF5xx architecture.
We will be shortly stopping our support and maintenance of these products.
The documentation currently hosted on the blackfin.uclinux.org website will no longer be available. However the sources and binary distributions will still be available from SourceForge at the following locations:
Buildroot and kernel
Support for Blackfin uCLinux can still be obtain by the community group at https://ez.analog.com/dsp/software-and-development-tools/linux-for-adsp-sc5xx-processors/
Analog Devices continues to support Linux for the ADSP-SC5xx processor family. For more information please visit https://www.analog.com/en/design-center/processors-and-dsp/evaluation-and-development-software/linuxaddin.html
Analog Devices believes in Open Source Software and continues to support the effort. For more details see https://github.com/analogdevicesinc
Please let me know where to get old documentations that many links even in SourceForge are referring to "docs.blackfin.uclinux.org" and it could not be resolved now.
