GCC tool chain version 4.8.4201803 supported for RXv3 (RX66T)?
Hi everyone,
I have a question is GCC tool chain version 4.8.4201803 supported for RXv3 (RX66T)?
According the release note on web site: https://llvm-gcc-renesas.com/release-notes/rx/latest/4.8.4.201803/release_notes.pdf
This version supported for RX66T, but when I built workspace with device RX66T, I got an error.
How can I resolve?
Thank you,
Hi Erika,
I think it should be -misa=v2, not -mcpu=v2
Please kindly confirm
Thank you

We are aware of this problem. A fix for this issue will be available for the next GCC for Renesas RX toolchain release. As a workaround please try using the -mcpu=v2 option along with RXv3.

Hello Erika Molnar,
Thank for your answer.
When I tried V2 option for RX66T, I built with no error. So, V2 and V3 as the same? and can I use -mcpu=v2 option for RX66T with no limitation?
Thank you,
Ly Dang
Hello Ly Dang,
There are no limitations for using the -mcpu=v2 option with RX66T. Due to an unfortunate omission in the compiler, the RXv2 instructions are disabled when using RXv3, the next GCC for Renesas RX toolchain release will contain a fix for this issue.
