Hi all, I am having some doubts regarding the flashes. I am having two types of flash. One flash is of ST make (M29W040B) having two chips of 512kbit size (total size is 1MB). The total sector in each chip is 8. and another flash used for storing code. This is of AMD make (AM29LV160B).It is also of two chips with 2MBit and total is 4MB size.The total sector is 35.
Now my question is how to define these things in myboard.h file. ie #define CFG_MAX_FLASH_BANKS //what values i have to put for these defined variables #define CFG_MAX_FLASH_SECT // what values i have to put for these defined variable #define CFG_FLASH_SIZE //what values i have to put for these defined variable #define CFG_FLASH_ERASE_TOUT 8000 /* Timeout for Flash Erase (in ms) */ #define CFG_FLASH_WRITE_TOUT 5 /* Timeout for Flash Write (in ms) */ #define CFG_FLASH_LOCK_TOUT 5 /* Timeout for Flash Set Lock Bit (in ms) */ #define CFG_FLASH_UNLOCK_TOUT 10000 /* Timeout for Flash Clear Lock Bits (in ms) */ #define CFG_FLASH_PROTECTION
2. I came to know from datasheet of AMD that it is CFI complaint but i did get any info regarding ST make . Can anybody tell is this flash is cfi complaint or not. Please help me in this regard.
