QSPI problems on my ls1021a board

Hi,

 

I meet some problems while I try to access QSPI flash in linux kernel. What I write into/read from QSPI are different.

The linux kernel can recognize my QSPI flash - s25fl256s, but when I try to erase/read/write it, I get some error message:

erase:

fsl-quadspi 1550000.quadspi: can't surport opr dc

read

fsl-quadspi 1550000.quadspi: can't surport opr c

write

fsl-quadspi 1550000.quadspi: can't surport opr 12

They are from the function set_lut in spi-fsl-quadspi.c.

Is this a driver problem or a flash compatible problem?

 

Thanks
