Hi,

I am working with IMX6ULL-EVK. I want to create the QSPINOR partition but it not work.

Following the step test :

  • compile u-boot for quad-spi-nor
  • I obtain u-boot.imx-qspi1
  • set the u-switch of EVK to start in QSPI mode
  • power-on the EVK
  • download the file u-boot.imx-qspi1 into qspi nor flash through lauterbach emulator
  • reset EVK
  • stop the software in u-boot mode
  • set the env

    setenv bootargs 'console=${console},${baudrate} root=${mmcroot} mtdparts=21e4000.qspi:1m(uboot),8m(kernel),1m(dtb),-(user)'

  • save the env
  • reset EVK
  • linux boot (kernel and fs are on SD card)
  • $ cat /proc/mtd

    mtd0: 02000000 00010000 "21e0000.qspi"

  • I see only one partition

     

     

     

  • Why I don't see the partition programmed ?
