FYI: I haven't check the Spansion datasheet, but when Winbond datasheets say read instruction accepts SPI clock up to 50MHz it refers to the normal read instruction (0x03) and for higher clock you should switch to fast read instruction (0x0B) which can be done by adding m25p,fast-read to dts. I guess the situation with Spansion datasheets are the same. _______________________________________________ openwrt-devel mailing list [email protected] https://lists.openwrt.org/mailman/listinfo/openwrt-devel
