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 implementations.
Originally RTEMS had a one big linkcmd for each platform, which defines linker symbols (used in C code) and required sections. This has been improved with current BSPs (like ARM-based ones), by splitting up shared linkcmd parts (linkcmd base) and BSP specific ones that include the shared one. riscv_generic, given that it's old, follows the old way of having a single big linkcmd. You can change this for your new BSP.
