I have been looking on Readme, Dulg, list and could not find where is exactaly the hrcw for 8xx based systems.
Please read the MPC8xx User's Manual. The HRCW is a hardware issue. It cannot be set and not even read (directly) by software.
Looking at my image (either at the embedded system or the *bin file), I've found the magic number (0x27051956) in the begining of it. I thought it isn't the hrcw, so, I came around the /cpu/mpc8xx/start.S
No, that's indeed not the HRCW. Not even mine :-)
So, if the magic number is in the cs0, address zero, it will be at the data bus at the reset moment, if CS0 is asserted (better: if the device is activated).
No, the HRCW is asserted by external hardware.
I do not undestand. Is the magic number the HRCW?
No, it ain't. To most people it's just a magic number.
