MPC5606S: program Test flash block

hello,

I learned from the MPC5606S reference manual that the first 8KB of the Test falsh block may be used for user defined functions. I can read it now ,but I want to know how to program it?

thanks!

Hi,

here is simple example:

   /* unlock all blocks */
   CFLASH0.LML.R = 0xA1A11111; /* write password */
   CFLASH0.LML.R = 0x00000000; /* unlock all low and mid blocks including test flash primary */
   CFLASH0.SLL.R = 0xC3C33333; /* write password */
   CFLASH0.SLL.R = 0x00000000; /* unlock all low and mid blocks including test flash secondary */

   /* program double word to User OTP area of CFLASH0 */
   CFLASH0.MCR.B.PGM = 1;
   *(unsigned int *)0x00400000 = 0x11223344; /* interlock write */
   *(unsigned int *)0x00400004 = 0x55667788; /* program data write */
   CFLASH0.MCR.B.EHV = 1;
   while(CFLASH0.MCR.B.DONE == 0);
   CFLASH0.MCR.B.EHV = 0;
   CFLASH0.MCR.B.PGM = 0;

Notice that this is OTP area, it can't be erased.

Regards,

Lukas
