RTEMS ARMv8 Query

[Raghav Nayak]

Hey Ray,

Thanks for the info. Do you have any documentation to build toolchain for V8 through source builder?

With Regards
  Raghav

There are some BSPs for V7. But V8 is 64bit instruction and I do not know how well it is compatible with 32Bit instruction.

I think you can start with toolchain for V8 and begin with the cpukit folder porting regarding the context switch and ISR handling.
QEMU 32 bit emulation for AArch64 may help you with initial debugging and toolchain testing.

Hey Nick/Sebastian,

Then in that case if I need to work out for armv8 , Do you have any pointers to start with?

With Regards

As Sebastian pointed out, RTEMS doesn't currently support the ARMv8 anyway, so this wouldn't help you.
