i.MX8MMini FlexSPI QSPI NOR Flash Boot

[chenandy]

hello

     I want to imx8mm QSPI NOR Flash Boot.

     How do I set SW1101 and SW1102?

     uboot-imx  is use to imx_v2018.03_4.14.98_2.0.0_ga branch,

     make imx8mm_evk_fspi_defconfig

     It is will  generate to  uboot-imx/SPL,  u-boot.bin, u-boot-dtb.imx, u-boot-dtb.img, u-boot-dtb.bin , u-boot-nodtb.bin, u-boot.img,qspi_header.  uboot-imx/spl/u-boot-spl.bin  uboot-imx/spl/u-boot-spl-nodtb.bin

    How  I make SPL(QSPI NOR Flash Boot ) with those files?

    and  How  I make uboot(QSPI NOR Flash Boot ) with those files?

     I  want to Boot from emmc, and the firmware burn to NOR Flash through uboot,

     and boot from QSPI NOR Flash through to set SW1101 and SW1102

Hi igorpadykov

    I switched off the board and booted from QSPI,use to imx-boot-imx8mmevk-fspi.bin-flash_evk_flexspi,and that works well.

    but I want to know imx-boot-imx8mmevk-fspi.bin-flash_evk_flexspi is make up of files?

can you tell me? it is script for making?

Hi igorpadykov:

    I switched off the custom board and booted from QSPI, and QSPI NOR Flash is W25Q80DV.

I use default fspi_header, but the board works not well. How do I change this fspi_header

and  What do these parameters represent of fspi_header . Do you have detailed documentation of
fspi_header parameters?

Hi Andy

right, with default fspi_header W25Q80DV may not work well.
It is necessary to change it accordng to specific W25Q80DV parameters.
Unfortunately I am not aware of additional detailed documentation for changing
fspi_header parameters. May be suggested to use Commercial Support and Engineering Services | NXP 
as changes may be not simple and different for each qspi flash memory.

Best regards
igor

Hi Andy

one can look at Yocto Guide in linux documentation
i.MX Software | NXP
