How could I write and read in KEA64 EEPROM?

MartinFalcon95 — Tue, 15 Nov 2022 23:24:11 GMT

Hi! I'd like to know how to code for configuration, writting and reading EEPROM in a KEA64 (S9KEAZN64A).

My "bus CLK" = 20MHz

I already have the reference manual and I'm in chapter 18.

It could be very helpful if someone could share me an example code too please.

I'm working in CodeWarrior

Hi MartinFalcon95,

Please refer to the discussion in KEA64 EEPROM

Hope it helps.

Best Regards,
Robin

Hi Robin,

Thanks your your answer. I'm seeing the post you shared me and I have a question, if I'm using Code Warrior, the package in the image, "Keil.Kinetis" will work for Code Warrior? Thanks

I'm seeing the page from the link and it takes me to this:

Which of all is the version do I have to download?

Thanks

I have another question; how do you install the pack in Code Warrior once this is downloaded?

Sorry I didn't make it clear:

I did not find example for KEAZN64, but I think you can refer to the EEPROM_demo of KE02. Download the FRDM-KEXX Driver Library Package

Then you should be able to find the example (C:\Users\nxa07315\Desktop\FRDM-KEXX-Driver-Library-Package\ke_drv_lib\build\cw\ke02\EEPROM_demo)

This project is based on CodeWarrior. You don't need to download the Keil package.

KEAZN64 is a derivative from KE02Z64, so you can use it.

What is the process to adapt it?

I already downloaded the Package, and I have the EEPROM project in my workspace, I took the flash.c and flash.h to my project but there's some failiures,

is it really needed to add the common.h and the arm_cm0.h?

You may need to manually modify the EEPROM API in flash.c so that it does not depend on common.h and the arm_cm0.h
Sorry for the inconvenience we bring you!

These TRK-KEA64_LABTS1\2\3\4 examples contain only a few peripheral(UART\FTM\ADC\KBI) drivers.
Have you considered what to do if you need other peripheral drivers?

Maybe you should use Processor Expert to create a KE02 40MHz project, and then add the peripheral drivers you need.

Hello, thank you for the info.

So, if I create a new project, with KE02, it could work for SKEAZN642?

Re: How could I write and read in KEA64 EEPROM?

Yes. For example, if you are using KEAZN64, you can choose KE02Z64 when creating a Processor Expert project. The corresponding package needs to be configured in the project.

To create a Processor Expert project is necessary to create a "New MCU project"? Or It can be created inside of my current project?

Re: How could I write and read in KEA64 EEPROM?

Robin_Shen — Wed, 23 Nov 2022 00:37:35 GMT

Please create a "New MCU project" with Processor Expert.

Hello. I see this image in the datasheet but, I don't see where EEPROM memory start, between which directions EEPROM is available? (where does it start and where finish it?)

Thanks.
