RE: mpc555 internal flash programming

see the end of my email and also see Allen Dobbin's email.
 
program 0x0 into location 0x0 of the shadow block of the device. this
will enable the internal flash and cause execution to start at address
0x100.

Hi Dees,
Thanks a lot.
Pulling D20 to high and /RSTCONF to low worked. I could write into
internal flash. 
But now a new problem i am getting that is if i remove the debug probe,
And then power on the target, The code doesnot start to execute. 
If through debuger i give run command it executes.

In my program, I have given a jump to main at location 0x100 which is
the reset location of mpc555. 
This same code i have tested on phycore mpc555 evaluation board it works
over there. So is there anything specific we need to do in the hardware
to start executing from internal flash.

be sure to program HC bit in the flash reset config word to a zero (0b0)
to enable the flash in normal boot mode.
