.idcode1 = SPSN_ID_S25FL032A,.idcode2 = SPSN_EXT_ID_S25FL032P,.idmask2 = 0xff00,what does the idcode2 look like such that you need a mask ?
According to the datasheet the RDID command (0x9f) returns the following bytes:
byte 0: Manufacturer ID = 0x01 byte 1,2: Device ID = 0x02, 0x15 (same as S25FL032A) byte 3: Extended ID = 0x4d byte 4,5,6: Spansion reserved (do not use).
byte 4 is read as 0x00 on my part, but due to the above explaination, I cannot say for sure it is always the same, so I had to implement a mask to check for it.
i'd rather we delay adding code to support something that may never change. so drop the whole idmask2 stuff and wait for it to become an actual problem -mike
