in our imx6 solo lite board, using mx25l25635f spi-nor flash.
u-boot can read / write and probe, but it read / write speed is very slow.
i check on internet, it seem imx driver in u-boot only support 3byte mode.
does imx6 solo lite have mx25l25635f driver patch that support 4 byte mode in u-boot and kernel?
yes, i have tried fast_read, but i can't get any data that be saved before.
it alway return crc error and using default environment setting.
B.T.W: according mx25l25635f data sheet, it should support 4-byte mode.
I mean the i.MX6S Reference manual.
According to the Reference Manual, the boot only support 2 or 3 bytes addressing.
