help mx6q boot from spi nor flash

[lixuhui112]

Hi everyone,

I have designed a custom i.MX6 board based on MCIMX6Q-SDB board and am planning to bootup from SPI NOR Flash. I have run the DDR Stress test and updated the calibration details in my u-boot file,but the uboot not bootup .My nor flash chip is S25FL064P .I just change the following：

1.mx6qsabresd.c

/*........................uart1..........................................*/

static iomux_v3_cfg_t const uart1_pads[] = {

    MX6_PAD_SD3_DAT6__UART1_TX_DATA | MUX_PAD_CTRL(UART_PAD_CTRL),

    MX6_PAD_SD3_DAT7__UART1_RX_DATA | MUX_PAD_CTRL(UART_PAD_CTRL),

};

/*............................spi nor......................................*/

#ifdef CONFIG_MXC_SPI

static 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),

};

static void setup_spi(void)

{

    imx_iomux_v3_setup_multiple_pads(ecspi1_pads, ARRAY_SIZE(ecspi1_pads));

}

int board_spi_cs_gpio(unsigned bus, unsigned cs)

{

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

}

#endif

2 mx6qsabresd_defconfig

CONFIG_SYS_EXTRA_OPTIONS="IMX_CONFIG=board/freescale/mx6sabresd/my_mx6q.cfg,MX6Q,SYS_BOOT_SPINOR"

CONFIG_ARM=y

CONFIG_TARGET_MX6SABRESD=y

CONFIG_SYS_MALLOC_F=y

CONFIG_SYS_MALLOC_F_LEN=0x400

CONFIG_DM=y

CONFIG_DM_THERMAL=y

I do not know if there are any problems，Can anyone guide me please

thank you very much !!!

Hi xuhui

Sabre SD design unfortunately does not allow to boot from

spi-nor, as described in attached Release Notes Table 7. Known

Issues and Workarounds. It is necessary to follow Sabre AI design,

steps for spi-nor programming are given in sect.7.5 Flash U-Boot on

SPI-NOR  i.MX_6Dual6Quad_Sabre-AI_Linux_User's_Guide.pdf

Porting new spi-nor is described in Porting Guide Chapter 5

Configuring the SPI NOR Flash.

Best regards

igor

yes ,my board also made reference the Sabre AI design, I use the MFG TOOL down  my modified uboot on my boot ;

Bad Linux ARM zImage magic!

=>

but I'm not sure if uboot burned into the spi nor flash,I use this command:

  <LIST name="Nor Flash" desc="Choose Nor flash as media">    

    <CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot.imx" ifdev="MX6Q">Loading U-boot</CMD>

  <CMD state="BootStrap" type="jump" > Jumping to OS image. </CMD>

    <CMD state="Updater" type="push" body="send" file="files/u-boot.imx" ifdev="MX6Q">Sending U-Boot</CMD>

    <CMD state="Updater" type="push" body="$ dd if=$FILE of=/dev/mtd0 bs=1k seek=%seek%">write U-Boot to NOR flash</CMD>

    <CMD state="Updater" type="push" body="$ echo Update Complete!">Done</CMD>

  </LIST>

and how can sure uboot is in nor flash

Thank you!!!
