RZ, KPIT GNU
embOS for Renesas RZ was developed for and with the KPIT GNU compiler and supports all memory models offered by this compiler.
It comes with easy to use start projects. Initilization code for different Renesas RZ starter boards is included.
Software development with with JTAG tools like J-Link is possible.
