How to read data from internal P-Flash for KL26?

yenhsu — Wed, 02 Aug 2017 11:36:19 GMT

Hello,

I am trying to use internal P-flash of KL26 as a NVM to save data, of course I will carefully not to access the area that stored binary source code to mess it up then cause the system crash. It seems to me that I can use "FTFA_FCCOB0" command to write or erase a sector, but I would like to know how to read data from internal flash for KL26. I will deeply appreciate if someone who can teach me about this? (It would be better if you can provide an example code for a reference.)

Thanks

Hello Chris chen,

Read flash data is very easy, just read the according address is OK, you don't need to use any other flash command.

Take an example, printf the data in address 0x0008:

printf("0x%x,",*((uint32_t *)(0x00000008)));

(uint32_t *)(address);//address is just the flash address where you want to read the data.

Wish it helps you!

Have a great day,
Kerry
