Dear All,

 

We designed the custom i.mx53 board having spi nor flash and we have chosen the SPI pins as shown below:

 

ECSPI2_SS1 = EIM_LBA     (Chip select 2  Signal coming from spi flash and going to Imx processor)

ECSPI2_SCLK=CSIO_DAT8 (Serial clock coming from spi flash and going to Imx processor)

ECSPI2_MOSI=CSI0_DAT9  (Mosi signal coming from spi flash and going to Imx processor)

ECSPI2_MISO=CSI0_DAT10 (Miso signal coming from spi flash and going to Imx processor)

 

ECSPI_SS1=EIM_D19     (Chip select 1 Signal coming from spi flash and going to Imx processor )

ECSPI1_SCLK=EIM_D16 (Serial clock coming from spi flash and going to Imx processor)

ECSPI1_MOSI=EIM_D18 (Mosi signal coming from spi flash and going to Imx processor)

ECSPI1_MISO=EIM_D17 (Miso signal coming from spi flash and going to Imx processor)

 

We are interfacing SPI NOR flash to boot the device.

 

Whether we can use chip select 1 or chip select 2 for booting the device?

 

 

 

Thanks,

Vidya
