Posted on February 18, 2008 at 08:52Hello All,
We are working on St10275 Cotroller for automotive application.
I am facing the strange problem in the flash driver.
The code for erasing the flash looks as below,
FCR0H = FCR0H | FLASH_TYPE;
FCR0H = FCR0H | SECTOR_ERASE;
FCR1L = sector_no
FCR0H = FCR0H |WMS;
after this code wait in the while loop till the LOCK bit is reset.
All these code is executed in RAM.
With this pice of code, i am able to erase the Xflash and the first 4(0-3) sectors of the Iflash.
If i tries to erase the 4th sector of the flash controller is getting the reset.
Please help me to solve this problem.
Regards,
Praveen
