While debugging an application with GDB the following might happen: (gdb) return Make xxx return now? (y or n) y Could not fetch register "fflags"; remote failure reply 'E14' This is because riscv_gdb_get_fpu calls riscv_csrrw_debug with a wrong csr number (8). It should use the csr_register_map in order to reach the riscv_cpu_get_fflags callback.
