Using the Internal FLASH for store data

alicetin — Thu, 12 Jan 2023 07:09:50 GMT

Hello,

I want to store any data in my Kinetis MCU's(MKV11Z) flash. I want to read last data value when mcu turn on. There are good pages like Erich Styger's Blog . I read it but I can't try code. Because I couldnt acces component inspector page at MCUXpresso.

Are there any way to store data in kinetis MCU? or example?

Thanks for the helps.

Hi @alicetin ,

I'm using the same (well, similar) approach with the McuLib which includes basically many of the former Processor Expert component functionality, but now ported to the MCUXpresso SDK.

You might have a read at:

I'm using it with an LPC55S16 here too:

The key part is in the McuFlash.c

It supports 'Kinetis', but I have used it only with the K22 and K02 family, and I don't have any KV one. So I assume you would have to implement the basic flash programming in McuFlash.c/h/config, but this should not be difficult (I hope).

I hope this helps,

Erich
