Flash writing

pietrodicastri — Fri, 29 May 2015 09:32:05 GMT

Good morning

I have programmed the flash using the MK60DN512VLQ10 and the acceleration RAM. It was always ok.

I have used the same code with the MK64FN1M0VLQ12 and it does not work, I get out of the programming command, FlashProgramSection, the

0x20 meaning FTFx_ERR_ACCERR .

Any suggestion???

Thank You

Hello Pietro,

K60 and K64 are using different versions of the Flash controller to program the internal Flash memory. Because of that reason the same code won't work in both devices.

K64 is using the same Flash controller as the K60 120 MHz family. You can create an example based on Processor Expert or you can download the Kinetis KSDK 1.2.0 and go to the folder KSDK_1.2.0\examples\frdmk64f\demo_apps\flash_demo to find an example.

Regards,

Santiago

Hello everybody,

I don t see relevant differences in the URM. I used the EERAM for programing, it should be available in the K64.

The example of the KSDK works, but I would like to understand why mine it does not work.

Help,,,,

Thank You

Pietro

Hello

Just dump a project example using the EERAM for programming the flash, that's a good help.

The example in the SDK is not using the EERAM..

Thank You

Pietro

Hi,

Freescale provides C90TFS Flash driver software (Kinetis Flash driver includes demos).

Customer could refer K70, which using the same Flash architecture with K64. There with example demo about how to program the Flash.

Wish it helps.

Have a great day,
Ma Hui
