No support for CFI algorithm 1793 on 16 bit flash

hi,

When i program the sst39vf160 nor flash in NiosIDE , a problem happend:No CFI Table found at address .... i search the help doc and serch internet ,i find that the override file is needed,so i use nios2-flashprogrammer --debug --base=0 and the consol prints the flash 's CFI table ,and reprogram flash by the arg( override file), and it told me that "CFI erase region definitions don't match device size" below is my override file:

[FLASH-00BF-235B]

CFI[0x10] = 0x0051

CFI[0x11] = 0x0052

CFI[0x12] = 0x0059

    all reported values are 8 bit the upper 8 bit are always 00

    check if you flash is in 8 bit mode

    next check if you use 16bit mode that nios adr 0 is not connected as adr bit 0 it is always 0 in 16 bit accesses

    nios a1 should go to flash a0, but some manufacures like spansion label adr bit 0 as a-1 if it is a 16 bit device with 8bit mode.

    regards

    thanks &#39;MSchmitt&#39; , i have cheched my board and the flash is working under 16bit mode. nios A1 is connected to flash a0,sst39vf3201 dosent have a-1 pin, a0 is addressed a byte! perhaps i discriped it not deeply , i provide the nios2-flashprogrammer --debug --base=0 :

    Using cable "ByteBlasterII [LPT1]", device 1, instance 0x00

    Resetting and pausing target processor: OK

    Found CFI table in 16 bit mode

    Raw CFI query table read from device:

    No CFI override data for [FLASH-00BF-235B]

    CFI erase region definitions don&#39;t match device size

    That's a bug, it can't be use in 16-Bit mode for program the Flash. We can use 8-bit mode, that's ok.
