DCF record flash code

[yuriy_serdyuk]

Hi All,

I try to flash DCF record with code from example

C55FMC.LOCK0.R &= 0xFFFFFDFF;

/* Program one page in the mid block */
C55FMC.MCR.B.PGM = 1;
*(unsigned int*)0x400638 = 0x0; 
*(unsigned int*)(0x400638+4) = 0x0;
C55FMC.MCR.B.EHV = 1;
while(C55FMC.MCR.B.DONE == 0);
C55FMC.MCR.B.EHV = 0;
C55FMC.MCR.B.PGM = 0;

But it was not success.  Can you help me?

Thank you
