S32K312-Erase Flash Block Interface

Simon-Liu — Mon, 21 Aug 2023 10:02:08 GMT

Hello

When I use DS3.5 to generate C40 code to operate Flash, I found that there is only an interface for erasing Sector (C40_Ip_MainInterfaceSectorErase) in C40Ip.c, but I checked RM and found that bit[ESS] of register MCR can be set to erase Block of. Is there an interface to erase the Block?

BestRegards

In the RM 21.7.1.2, you may read statement that:

„Block erase is for Factory use only, under controlled conditions.“

The Program/Erase cycles value is specified as 25, when using the Block Erase. That’s why flash drivers and external tools do not use this operation.

Thank you for your answer.

I saw this description in RM before, I thought that there was a way to enter the factory mode, now I understand that the block cannot be erased by the driver.
