In fact I'm using OMAPL138 platform and I think that it is not UBL that is copying kernel under that platform.
I have been able to find the kernel image relocation in cmd_bootm.c but that is not the inital copy. 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. Any idea?
