Hi @gzhan88, it looks like you are trying to access physical memory after attaching gdb to the core running on virtual memory. This errors, because 0x40000000 and 0x80000000 are not mapped to the virtual memory space. If, however, this is what you want, you need to remove the following lines from ariane.cfg: https://github.com/openhwgroup/cva6/blob/4abae602c57045a2c89147a2c9c2cc47eab8fc14/fpga/ariane.cfg#L38-L40 This will result in the debugger exclusively accessing physical addresses. Best, Nils

Hi niwis,thank you very much for your prompt reply.The problem has already been settled.

hi，I can not log in to linux by default username root when starting the operating system. Nothing happens when I type root , and the log is same as you.
