[Ppcboot-users] Flash Booting problem

[Manuel T. Dall'O. <mt...@tc...>]

I will explain better my question.

I based my design on the STK8xx, so I prefer the ISB set to 11 (0xFFF0000=
0
initial PC).   I will take in consideration your change to 0x000000000 bu=
t
like last option because implied a hardware wire.


1) Is your processor running (reset released)?  Hardware as well as JTAG?
Yes, The procesor work well by JTAG.  It detect my FLASH and let me write=
 and
read RAM/ROM.

2) How are you debugging the board?  BDI-2000 (highly recommended)?
I am debbuging by GDB-5.0

3) Is your memory programmed properly?
Yes, when I work in debugging mode I have a complete control of the
hardware.

   a) How did you program your memory?  Did you verify it was
         programmed OK?  Your statement of writing ROM with gdb is
         confusing since gdb doesn't know how to write flash.

    By the GBD, I write the bootloader in random position and it was read=
 OK.


    b) Are you driving the Reset Config word? Verified with a scope/logic
          analyzer?

    It was indirectly by the register values.


4) Are all of your selection jumpers jumpered correctly (especially
 RSTCONF*)?

  Yes, my word is 0x41E0





My Register value are:
