In fact I'm using OMAPL138 platform and I think that it is not UBL that is copying kernel under that platform.
The UBL set up the processor in a fixed way, and have no knowledge about the kernel. It loads u-boot, and the kernel is copied inside u-boot.
I added printf/puts into the code to find where exactly it happens and my last print before the copy is displayed from
file: hush.c function: static int run_pipe_real(struct pipe *pi) line: rcode = (cmdtp->cmd) (cmdtp, flag,child->argc-i,&child->argv[i]);
This is a function pointer and I just don't know where it jumps and it's what I trying to find.
Of course, you find only the point where the shell starts the function executing a command. However, as already reported, you have to take a look to the "cp" command, whose function do_mem_cp is in common/cmd_mem.c.
