Hi Denis,
You just need to modify riscv_interrupt_disable(). Read the priv-spec
manual for your RISC-V version, and determine which bit should be
cleared (it's called MIE in priv-1.10, but you mentioned you work with
priv-1.9).

Hi Denis,
As per my previous reply, it is gonna be a challenge to make RTEMS
exes fit in 16 KiB of RAM, so it's a good idea to do some analysis on
the compressed ISA.

I found out that there is 16 KiB of RAM. So, Freedom E310 chip has only 16
KiB of RAM.
And Freedeom E310 chip is based on E31 Coreplex core that allows maximum of
64 KiB of RAM.
So, I was just a bit confused with these names at first.

Hi Denis,
Does your board support any accesses to > 0x8000. Note you still
use such region in your linker script, which shouldn't be used if your
board doesn't support it. I'd suggest your read about memory mapping
on your board and fix the linker script accordingly.

Hi Denis,
In riscv_generic, only context switching is supported. It was supposed
to only run hello world (console) and ticker (tickless timer), both
don't need interrupts. I assume you can do the same for HiFive1, which
is the simplest. Then we can discuss about the timer and interrupt
