Working and Calibration Page implementation for S32K3

[HemantK]

Hello All,

We are in process of implementing XCP protocol for our project.
One of the features we are implementing is support for calibration.

It seems that S32K3 doesn't support MMU which is required for Working and Calibration Page switch.
I was wondering if we have missed something whilst reading the datasheet.

If not then can you please guide us with how to achieve this.

hello, HemantK

Currently, we also intend to implement xcp based on s32k324, so have you figure out the solution for Working and Calibration Page switch? looking forward to your reply.

Hi @HemantK 

Unfortunately, no hardware support for flash overlay with current S32K3 devices. It requires user programs to implement FLASH-RAM mapping. The FLASH-RAM data synchronization can be implement by a task or state machine, it similar to the EEPROM in MCAL driver.

S32K39x/37x devices (currently silicon and enablement (documentation, software and boards) NDA required) have a module capable of providing this feature.

Many thanks for the feedback.

We will look into what can be done
