Why nor flashcan not storage the data

lixuhui112 — Fri, 08 Jul 2016 07:44:07 GMT

We had designed a custom board based on imx6qsabre-AI , but the nor flash storage the data , the code is

#ifdef CONFIG_MXC_SPI

iomux_v3_cfg_t const ecspi1_pads[] = {

MX6_PAD_CSI0_DAT4__ECSPI1_SCLK | MUX_PAD_CTRL(SPI_PAD_CTRL),

MX6_PAD_CSI0_DAT5__ECSPI1_MOSI | MUX_PAD_CTRL(SPI_PAD_CTRL),

MX6_PAD_CSI0_DAT6__ECSPI1_MISO | MUX_PAD_CTRL(SPI_PAD_CTRL),

MX6_PAD_CSI0_DAT7__GPIO5_IO25 | MUX_PAD_CTRL(NO_PAD_CTRL),

};

void setup_spinor(void)

{

imx_iomux_v3_setup_multiple_pads(ecspi1_pads,

ARRAY_SIZE(ecspi1_pads));

gpio_direction_output(IMX_GPIO_NR(5, 25), 0);

}

int board_spi_cs_gpio(unsigned bus, unsigned cs)

{

return (bus == 0 && cs == 1) ? (IMX_GPIO_NR(5, 25)) : -1;

}

#endif

Hi xuhui

for saving environment parameters in spi-nor please check

definition in uboot/include/configs/*board*.h file :

#define CONFIG_ENV_IS_IN_SPI_FLASH

Best regards

Re: Why nor flashcan not storage the data

lixuhui112 — Sat, 09 Jul 2016 06:52:31 GMT

in my uboot/include/configs/borad.h file is such as :

#ifdef CONFIG_SYS_USE_SPINOR

#define CONFIG_CMD_SF

#define CONFIG_SPI_FLASH

#define CONFIG_SPI_FLASH_STMICRO

#define CONFIG_MXC_SPI

#define CONFIG_SF_DEFAULT_BUS 0

#define CONFIG_SF_DEFAULT_CS 1

#define CONFIG_SF_DEFAULT_SPEED 20000000

#define CONFIG_SF_DEFAULT_MODE (SPI_MODE_0)

#define CONFIG_ENV_IS_IN_SPI_FLASH

#endif

but it's the same than I Turn off the power and restored my save data is not in spi-nor flash

After testing found that flash memory can be an environment variable, but can not use，such as :
