4 years ago The warning comes from the statement "WARN(1, "failed to read DBI register, addr=0x%04x\n", addr);" The problem happened earlier, but you did not provide that log.
These are the kinds of issues that I cannot help you solve. Please read README.md and report the problem in the manner suggested there.
