hiii

i have interfaced  CY8CKIT-050 kit and W25Q128Fv flash chip using http://www.cypress.com/documentation/code-examples/ce204087-interfacing-spi-nvram-psoc-35

it works good upto 350kHz frequency but it doesnt work more than that frequency, in the datasheet they have mentioned that it works upto 4MHz

what might the reason behind this?

how can i solve this?

Watch out to which pins you connected the flash chip (look at the -050 kit schematic). Some of them are used for other peripherals, and some of them even have capacitors attached. This can wreak havoc with the signals.
