Having a problem when write data into on chip flash

jqy — Thu, 03 Aug 2017 09:02:31 GMT

I tried to modify the demo code" frdmkl03z_driver_examples_flash_pflash". i coped the code from the main() to my code. It works fine to initialize the driver, read the data and even erase the sector. The problem is when it programmed the data in to the flash sector, a hard fault event happened. Any idea about this problem?

i couldn't run the demo code on my own development board.

See http://www.utasker.com/kinetis/FRDM-KL03Z.html
At the bottom of that page there is a binary that you can try and also a link to a video explaining the operation. All code, including a number of different parameter system options, is available in the uTasker project (allows also simulation of the KL03 and its internal Flash operation).
