MPC5748G DCF

hi,

i see the MPC5748G reference manual , about the UTEST Memory Map section.

the address 0x004000C0 is Soft DCF Record Start Address;

the address 0x00400300 is DCF Start Record;

the address 0x00400308 is Reserved;

the address 0x00400348 is DCF Records;

It makes me wonder , if there has some different between the Soft DCF Record and DCF Record ?

the address 0x00400308 is reserved , can i write something into this area?

Hello,

It makes me wonder , if there has some different between the Soft DCF Record and DCF Record ?

Those are the marks for SSCM machine to read and copy data to correct locations.

the address 0x00400308 is reserved , can i write something into this area?

No. You will write DCFs to :

0x00400348 -- 0x00400FFF 3256 DCF Records
0x00401000 --0x00403FFF 12288 Reserved for customer OTP data

Avoid write to reserved areas at all.

Best regards,

Peter
