looking for sample and simple C code for A53 based SoC

hi Ronan,

I am able to go to the documentation that explains the flow to run an example test but I am not able to find the download link itself.

In the getting started section, point #4, it says, "point to the download path where you downloaded the file"

Thanks

See "Support Files" here:

Thanks. A couple of follow-up questions please.

1) i guess the execution flow is that the processor starts with startup.s and then jumps to main.c

If this is the case, how it is specified that the startup.s should be placed at the address from where the processor starts execution?

2) how it is specified that code has to jump from startup.s to main.c?

The only other file I see is the scatter.txt but I dont see anything that specifies these.

1) The linker option --entry is used to say that this is the first instruction to execute. You are correct that in this case, it is not explicitly placed first in the code area, but just picked up by the catch-all "* (+RO)" line.

You could add to the scatter file with something like:

  BASE 0x80000000
  {
	 startup.o (BOOT, +RO)
     * (+RO)
  }

2) The startup code ends with a branch to __main, which is the start of the C library initialization code... this will ultimately get to main(), where your application begins.
