KW36 flexNVM EEPROM not working

Hi,

I want to use FlexNVM EEPROM functionality of KW36 & I'm trying the example in SDK "FlexNVM_EEPROM" for testing. However, the example does not seem to run on the go & I'm getting following error on debug -

There is no available EEprom (FlexNVM) on this Device by default.

I have not made any changes in the example code. I found that error is observed for flash_command_sequence function & further in that after following call is executed, I am getting flash access error.

callFlashRunCommand((FTFx_REG8_ACCESS_TYPE)(&FTFx->FSTAT));

 

 

Can you please help me with this issue.

Some relevant information : 

- I am testing on freedom board FRDM KW36

- MCUxpresso IDE 11.2.1

- SDK version 2.2.6

 

Thanks in advance,

Abhijeet

Hi,

I test the sdk. It doesn't work. I refer the other mcu's eeprom finding that this sdk may has some problems. I modify the example. You can use the attachment to test. By the way, this program is built by mcuxpresso 11.3. I am not sure if it will work on 11.2. This is the result.

Hi,

Thanks for your input.

I tried your example both on MCUXpresso 11.2 & latest 11.3 with latest SDK 2.2.7, but I got the same error.

Between, before trying this EEPROM example, I was testing OTAP client example with internal flash as file storage. So, is it possible that flash configuration is unable to be overwritten?

I also tried with mass erase but to no avail. 

 

Thanks in advance,

Abhijeet

Hi,

Before you do this test, you should do full chip erase, or this may failed. I used IAR to erase the memory. You can have a try.
