Hi All, I am using is S29GL064M90TAIR32 flash memory and my board is ep8248 based (customized), where as in file board/ep8248/flash.c (In U-boot Source) support for Am29LV320MT/B flash is provided.
Since both the flash memories are 0.23 u Mirror Bit and CFI Compliant,
Can I use the board/ep8248/flash.c file for S29GL064M90TAIR32 flash with minor changes like flash size, Total Number of Sectors, Start address of all the sectors of the Flash Memory , Manufacturer Id, device Id, Base address of the Flash Memory.
Do I need to change the "command sequence" i.e the statements prefixed with V_ULONG
e.g /* Write auto select command sequence and test FLASH answer */ V_ULONG(baseaddr + ((ulong)0x0555 << 2)) = 0x00AA00AA; V_ULONG(baseaddr + ((ulong)0x02AA << 2)) = 0x00550055; V_ULONG(baseaddr + ((ulong)0x0555 << 2)) = 0x00900090;
manf = V_ULONG(baseaddr); /* manufacturer ID */
Since both the Flash memories belong to the same family (i.e Mirror Bit Family), I think that command sequence has to be same, but I am not sure about. Please correct me if I am wrong.
