program with acess to IMX7D Qspi

hi everbody

i like to use qspi spi-nor on imx7dsabresd

i depoluated and polulated related Resistors

with mx7dsaresd_defconfig i added some define in imx7dsabresd.h and qspi related device tree ( i like to support sd and qspi and nand in u-boot)

what did i miss ? or how can i debug this problems ?

these are what i added in imx7dsabresd.h

#define CONFIG_FSL_QSPI

#define CONFIG_CMD_SF

#define CONFIG_MTD

#define CONFIG_DM_SPI_FLASH

#define CONFIG_SPI_FLASH

#define CONFIG_SF_DEFAULT_MODE 0

#define CONFIG_SF_FLASH_MACTRONIX

#define CONFIG_SF_DEFAULT_BUS 0

#define CONFIG_SF_DEFAULT_CS 0

in u-boot i can probe qspi nor flash but i can't write or read ( not sure which is wrong , maybe both)

if i read spi-nor flash , no error messag but nothing is read

--- from u-boot console
