Hello,
I am trying to access NOR from bare metal application. My understanding is as it is connected through IFC, we need to access NOR through IFC. Currently I can see as it is mapped at 0x60000000 and I can read the data directly from NOR as buffer. But I am not getting clear understanding how can i write, erase the NOR sectors. I am not able to understand how to send the program / erase command sequence to CFI NOR. Can you please provide some reference for the same?
So for writing as per CFI command sequence can I use something like below
Writing 0xAA at address 0x0x60000100
#define NOR_DEV_BASE_ADDRESS 0x60000000
{
volatile uint16_t *cfi_nor_flash_base = (volatile uint16_t *)NOR_DEV_BASE_ADDRESS;
volatile uint8_t *cfi_nor_flash_8x_base = (volatile uint8_t *)NOR_DEV_BASE_ADDRESS;
cfi_nor_flash_base[0x555] = 0xAA;
cfi_nor_flash_base[0x2AA] = 0x55;
cfi_nor_flash_base[0x555] = 0xA0;
cfi_nor_flash_8x_base[0x100] = 0xAA;
}
Thanks & Regards,
