program with acess to IMX7D Qspi

[hyoungkikim]

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

Hi Hyoung

one can try to use proper dts files:

https://source.codeaurora.org/external/imx/uboot-imx/tree/arch/arm/dts/imx7d-sdb-qspi.dts?h=lf_v2021...

https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm/boot/dts/imx7d-sdb-qspi.dts?h=lf-...

hi  igor

i did it already,  in u-boot    wth dm command   i can see  that device tree node 

eth_phy_ge 1 [ + ] eth_phy_generic_drv | | `-- ethernet-phy@1
spi 0               [ + ] fsl_qspi                        |    |-- spi@30bb0000
spi_flash 0      [ + ] spi_flash_std              |     | `-- mx25l51245g@0

is there any thing  i shoud check ?  

thank you
