EEPROM TWRkit

[xavierbuhot]

Hello,

I would like to use the eeprom on my k60 kinetis so I found the example supply with th TWRkit.

When I launch the program the EEPROM still lock and never ready, the program are still running at that sentence:

	/* Wait for the command to complete */
	while(!(FTFL_FCNFG & FTFL_FCNFG_EEERDY_MASK));

Can someone help me?

Best regard.

I just notice that I get the TWR_K60N512 and there is not FLEXNVM memory, it is a devices with program flash only.

So I can use the flash to store all the data? How can I setup the flash part (at that range adress 0x1400_0000–0x17FF_FFFF) to b able to use it?

Is there any example?

More informations about my problem.

I try to put my program into RAM and try to write on flash blocks. But I still have Hard fault and vector 3 interrupt.

Is it really possible to write in flash memory?

Please ... :smileysad:

Hello Xavier:

I noticed you submitted a Service Request about these questions. Are your doubts clarified?

Just to summarize:

- You are correct, K60N512 does not have Flex NVM. But yes, you can still use part of the program flash to store non volatile data.

- You cannot use range 0x1400_0000–0x17FF_FFFF, since this is not present in your  device.

- The available flash memory in K60N512 is from 0x00000000 to 0x0007FFFF.

- For Flash memory storage and code examples, you can refer to Freescale Standard Software Driver (C90TFS), downloadable from the next link:

I hope this helps.

Regards!,
Jorge Gonzalez
