Now I have a problem: https://github.com/embeddedden/rtems-riscv/blob/hifive1/c/src/lib/libbsp/riscv32/hifive1/start/start.S#L117 When I step to that line, gdb hangs with a message: (gdb) step Note: automatically using hardware breakpoints for read-only addresses. Does somebody know what can be done here? Also, I don't like my initial linker file: https://github.com/embeddedden/rtems-riscv/blob/hifive1/c/src/lib/libbsp/riscv32/hifive1/startup/linkcmds Critique is very appreciated. -- Regards, Denis Obrezkov
