I'm downloading program from CAN and saving the content on P-Flash addresses mentioned in s19 file. After writing is finished, I want to check that if data written correctly. CRC32 is used for this purpose. But when I want to read the content of P-Flash addresses using pointers, it returns me 0xFF or 0x00. I have multilink &amp; can see the amount of Flash in Hi-wave is correct. Any guide to read content of P-Flash correctly. It that cause can it be used as EEPROM for writing data?</P><P>Thanks for your responses.</P> Sun, 01 Nov 2020 15:02:58 GMT margieenovak 2020-11-01T15:02:58Z https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Read-Content-of-P-Flash-From-BootLoader/m-p/1176246#M17564 <P>Hi, I'm working on a bootloader program based on AN4258 application note for MC9S12G128.
