Renesas e²Studio

IDE based on eclipse CDT for Renesas embedded controllers.

Renesas e²Studio can be used with Renesas' compiler toolchain as well as other toolchains and offers J-Link support for the RX Family via GDB and GDB Server.

e²Studio automatically uses the J-Link built-in flash loaders, when it is set up to use J-Link. J-Link built-in flash loaders are highly optimized for flash programming.
