PROGRAMMING THE S32K FLASH

Hi,

I'm planning to implement a boot loader on the S32K144EVB which is going to be used as basis for the production bootldr.

I'm planning to start my boot loader at location 0 and the APP at the 1ST 64Kbyte boundary. which will be accomplished by writing the offset in the VTOR register and then jump to 0x10004 after the APP image has been flashed.  

My QUESTION IS:

Can I issue the ERASE and PROGRAM command from the boot loader residing in the flash section starting at 0x00 to 0xffff targeting the application locations(0x10000-- whatever)?

 

If the answers is yes then what are the sections of the flash that this could be done?

and what is the following paragraph actually stating(page 714 ref man)?

 

 

While executing from a particular PFLASH read partition , FTFC commands (except

parallel boot) cannot run over that PFLASH read partition.

Knowing that s32k144 has only one partition of 512k.

 

 

Now is parallel boot is a normal boot the one that takes place every time the board is powered up?

This a bit confusing,

 

Thanks,
