falsh erase

Hello,
Recently I was working on a project using the S32K344 chip, and while using flash I found a problem that the area between 0x0040 0000 and 0x0050 0000 could not be erased. However, erasing after 0x0050 0000 is no problem.

Hi @Jackson_Ping,

The memory in the range of 0x400000 - 0x500000 is Block 0.

S32K3xx_Memory_Map.xlsx

While the flash controller is performing a flash operation at Block 0, the cores and other masters must not access the block.

Refer to AN13388 S32K3 Memories Guide

Here is a discussion on how to place the C40_Ip driver into SRAM:
