+How to use U-Boot with SPI flash on NXP i.MXRT1050 EVK +------------------------------------------------------
+- Build U-Boot for i.MXRT1050 EVK:
+.. code-block:: bash
- $ make mrproper
- $ make imxrt1050-evk_spi_defconfig
In the previous patch, the new defconfig is called imxrt1050-evk_fspi_defconfig.
- $ make
+This will generate SPL, uboot.img, fspi_header.bin, and the final image (flash.bin).
+To boot from SPI flash on other boards you may need to change the flash header config, +that is specific to your flash chip, in Kconfig. +The flash config is 4K in size and is documented on page 217 of the imxrt1050RM.
It would be helpful to mention the SPI NOR flash part number that is used on the i.MXRT1050 EVK.
