Debian SuperH (SH4) port

SuperH (SH) is a RISC Architecture created by Renesas Electronics. SuperH is used in embedded systems such as cellular phones, NAS, LCD TVs etc. The Open Processor Foundation are reviving SuperH as an open source architecture.

Target

Renesas SH has many types of CPU (SH/SH2/SH3/SH4 and bi-endian).

The Debian SH (SH4) port project is active for supporting SH4 (m4 and m4a).

The SH3 CPU type can be supported as well, but sh3 is no longer developed and work is shifting to SH4.(Renesas does still sell SH3.)

Similarly, it is difficult to build the environment where buildd works for SH3.

Therefore, development is focused on SH4.

The Open Processor Foundation plans to support SH4 in their J-Core CPUs in 2017.

Cross compiler

Cross compilers can now be installed directly from the main Debian repositories thanks to the efforts of Matthias Klose (doko):

# apt-get install gcc-sh4-linux-gnu g++-sh4-linux-gnu
