Is there are flash example for the K20?

[rhana]

Hello,

   I am looking for a flash example for the k20 (specifically for TWR-K20D72M.)  Is it different than for the k60 or is writing to the flash the same for the kinetis family?

Thanks.

Flash writing is identical for the K20D72 and K60 (without FPU).

The following gives some details Re: Re: Serial number programming in production - Kinetis K10 (towards end)

Generally the differences (valid for KE, KL and K parts) are:

- parts with FPU and KE parts use phrase programming (8 bytes at a time) and other parts use long word programming (4 bytes at a time)

- the sector size varies between 512 bytes (KE parts), 1k (KL parts and some slower K parts - <= 50MHz), 2k most other parts, and 4k for FPU parts

There is a Flash driver that supports (automatically adapts itself to) all KE, KL and K parts in kinetis.c at http://www.utasker.com/forum/index.php?topic=1721.0

Hello Robert:

If you installed CodeWarrior v10.6, there is a Flash example for your board using processor expert at the next path:

C:\Freescale\CW MCU v10.6\MCU\CodeWarrior_Examples\Processor_Expert\Kinetis\TWR-K20D72M\FLASH

In case you do not like or simply don't want to use PEx, you can always download the C90TFS Driver from the next link:

http://cache.freescale.com/files/32bit/software/C90TFS_FLASH_DRIVER.exe

The package includes examples and instructions on how to use the flash APIs.
