Which part shall I copy, does 0x000 - 0x3FF registers region and 0x1000 - 0x3FFF RAM matter(it seems cannot erase and PGM directly by loading the .s19 file), we need to take them into consideration or not?</P> Sun, 10 Mar 2024 03:14:43 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/MC9S12DT256-memory-copy/m-p/1824560#M19712 Neo_zhang 2024-03-10T03:14:43Z https://community.nxp.com/t5/S12-MagniV-Microcontrollers/MC9S12DT256-memory-copy/m-p/1825007#M19714 <P>Hi,</P> <P>the S19 record is stored only in the P-Flash memory.</P> <P>Of course you can have something also in the EEPROM memory but it depends on your application whether the EEPROM was also loaded with some code.</P> <P>However, usually...almost 100% of projects have entire code placed in the Flash memory.</P> <P>RAM and registers are not important because registers have their reset status and RAM is RAM.</P> <P>Best regards,</P> <P>Ladislav</P> Mon, 11 Mar 2024 09:46:47 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/MC9S12DT256-memory-copy/m-p/1825007#M19714 lama 2024-03-11T09:46:47Z
