XRDC Memory regions

FabioG — Thu, 11 Apr 2024 08:28:13 GMT

HI there,

I don't understand the cross reference between MRC Slave protected PFLASH_0, PFLASH_1,...PFLASH_WR, ...,PRAM0,PRAM1 (see below)

and the s32k3xx_Memory Maps where FLASH splitted in program flash data flash and ram is splitted in SRAM0,1,2 (see below). I need to know that in order to configure xrdc configurations

Can you help me ?

Hi @FabioG,

You can see the ports in the block diagram.

Figure 8. Block diagram – S32K324, S32K344 and S32K314

The PFLASH_WR port is for writting/programming the flash (not depicted), while other ports are just for reading.

Refer to RM sections:

22.1.1 Flash memory architecture

23.1 Chip-specific PRAMC information

Regards,

Daniel
