Hi Joel,

After bootstrap if I want to add something for configure do you have any steps?

Hi,

I could build the armv8 toolchain properly but do I need to do anything else to build RTEMS other than providing the toolchain path

There is no 64-bit aarch64 port of RTEMS. One would have to be written.

In the mean time, you can run 32-bit ARMv7 code on the same CPU but not take advantage of newer instructions in 32-bit ARMv8 mode.

With Regards
 Raghav

Yes, I will do this once the next gcc snapshot is made which should be in a day or so.

I will add this to rtems-tools.git/tools/4.12.
