Hii sir,
I am using sdk v04.00.00.04 and AM335x EVM processor.
I want to read and write part no and serial no. for SPI FLASH.
I built dts file for spi flash memory (w25q64) but I don't know what is the next step after this for spi flash configuration?
I have attached am335x-evmsk.dts file.

And we need to modify in mux.c or it's ok? I am using this mux.c for spi0 :-
static struct module_pin_mux spi0_pin_mux[] = {
{OFFSET(spi0_sclk), (MODE(0) | RXACTIVE | PULLUDEN)}, /* SPI0_SCLK */
{OFFSET(spi0_d0), (MODE(0) | RXACTIVE |
PULLUDEN | PULLUP_EN)}, /* SPI0_D0 */
{OFFSET(spi0_d1), (MODE(0) | RXACTIVE | PULLUDEN)}, /* SPI0_D1 */
{OFFSET(spi0_cs0), (MODE(0) | RXACTIVE |
PULLUDEN | PULLUP_EN)}, /* SPI0_CS0 */
{-1},
};
I am using ti-sdk/board-support/uboot/configs/am335x_evm_defconfig for this spi.

Can anyone help me for this to do spi configuration.
I am stucking in this so many days.
