Re: about MPC555 PCB

hi,dir Allan,
  Firstly thanks your help!
  I just do according to your suggestion.But  it dstill doesn't work.
  Here I am trying to describe my steps to you,( All these are 
finished in the visionclick  7.0)  
  1.Select the ¡°00: MPC555 K1,2,3,M ( 448 x 8 ) 1 Device¡± Driver.
  2.Use internal RAM workspace starting at 0x003F9800.
  3.Set physical flash Base Address to 0x0.
  4.PREPARE the special *.BIN file and specify its path and file 
name.
  5.enable VPP to 5v, epee t0 3.3v and force Sys. rstcnf* connected 
to sreset* ,Clock to 40MHz.
  6.Click on ¡°Erase-only¡±. This will erase BOTH Shadow and Main 
Arrays.
  7.manually set CMFMCR_A SIE bit to ¡°1¡± in target beforehand. 
Program data into Shadow array (256 bytes), After completion, return 
the bit to ¡°0¡±.
   8.check that the CMFMCR_A SIE bit is
set to ¡°0¡±Program data into Main array (448K-bytes), here the 
speed is much slow and reach to 3 minutes(too long). But it come to 
success in programming the flash.
   After i finished these, and connected the power again, the board 
doesn't work.(by the way, the file burning to the board has been 
tested in the estsbc555 demo board, so i think the program is 
right!£©
   Here i suspect that the problem comes from the board? But the 
power. the clock, is right.
   What can i do? here I send you the .sch, and .pcb and .reg files 
to your email, hope you can find something in these!
   Thank you so much!
