Re: 回复： RE: [MPC500] How to use vision Click to program MPC555 shadow and boot from internal flash?

I use a simple assembly program that looks something like this:

_START:
;# use all the defaults
.4byte 0x0

;# reserved space
.4byte 0xffffffff
.4byte 0xffffffff
.4byte 0xffffffff

.byte "anything you want here to fill up te 256 byte shadow"
.end

You then assemble and link this at address 0 and you have an elf file
that CLick can convert to a bin file, to use to flash the shadow area.

Also, what version of VisionCLick are you using? You may need one of the
many, many patches available for VisionClick. Specifically, you will
need the patch that gives you the following flash programming algorithm:

MPC555 K2 CMF+SHADOW ( 448 x 8 ) 1 Device

THis is the one I use to successfully burn the shadow flash area with
VisionClick.

The diffrence of them is that in the former :CMFMCR_A   is 89FF00FF(SIE bit is 1 ) , and in the later : CMFMCR_A  is changed into 81FF00FF. But I still have some problems when operation in VisionClick to program the shadow.
>formerly    the board would read the reset configuration word form the databus and when i programming, I just program the Main flash and in visionClick I just select the : MPC555 K1,2,3,M ( 448 x 8 ) 1 Device Driver.
