Hi,i'm trying to erase a Flash sector on FRDM-KL25Z Freedom board using IntFlahs Bean.From the data sheet:
27.1.1.1 Program Flash Memory Features • Sector size of 1 Kbyte
I've prepared 3 sectors in Flash for store my code data,and i'have limited the code area to 64KB,then i've initialized some bytes in the 3 sectors
unsigned char __attribute__((section (".ParametersSection1"))) ParametersFlash1[512]={'S','e','c','1'};
unsigned char __attribute__((section (".ParametersSection2"))) ParametersFlash2[512]={'S','e','c','2'};
unsigned char __attribute__((section (".ParametersSection3"))) ParametersFlash3[512]={'S','e','c','3'};
i can verify that after programming the characters do appear in the memory modules
then i inserted the IntFlash Bean,naming it MyFlash,and in a point of my code i call
MyFlash_DisableEvent();
temp=MyFlash_EraseSector(0x18000);
I expect to see the sector 0x18000 - 0x183FF erased and full of 0xFF 0xFF...but it remains unchanged .
Probably it is not so simple and something is missing or i am completely wrong.
All the example i found are using a bean cold "Flash" instead of "IntFlash"
Can i have your help?
Thanks
