Both the versions of U-Boot and Linux kernel are very, very old. I
strongly recommend to use more current versions of the software.

Indeed. And what was the panic message? What was the contents of the
log_buf area?
I'm afraid you will have to type the commands to display the contents
of the log buffer yourself - you did not give instructions how to log
