how to erase the whole d-flash every time with PE micro

[gumu]

Hi NXP team,

when I download elf file via PE micro, the d-flash value can't be erased.

I'd like to know how to fix that.

Thanks!

Which device is this question related to?

MCU is S32K314.

Thanks!

Have you chosen right flash algorithm? (i.e. nxp_s32k314_1x32x1012k_hse_disabled.arp)?

In the debugger there is no other option that erase all, so it should always erase the whole flash memory block.

Otherwise it could be possible to use external tool like this:

Hi,

I find that FEE example have the same issue . Here is screenshoot:

The data flash should be erased after downloading code every time.

 but that is not the case at all.

I'd like to know which point I missed.

Thanks！

We have tested it and it really does not erase d-flash. I have reported it to S32DS expert and he creates ticket for this in order to modify ARP algorithms.

It's ongoing, even if the ticket ends up with PeMicro.

Possibly you could speed it up contacting PeMicro support:
