How to use U-Boot on NXP i.MXRT1050 EVK
|
|
---------------------------------------
|
|
|
|
- Build U-Boot for i.MXRT1050 EVK:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ make mrproper
|
|
$ make imxrt1050-evk_defconfig
|
|
$ make
|
|
|
|
This will generate the SPL image called SPL and the u-boot.img.
|
|
|
|
- Flash the SPL image into the micro SD card:
|
|
|
|
.. code-block:: bash
|
|
|
|
$sudo dd if=SPL of=/dev/sdX bs=1k seek=1 conv=notrunc; sync
|
|
|
|
- Flash the u-boot.img image into the micro SD card:
|
|
|
|
.. code-block:: bash
|
|
|
|
$sudo dd if=u-boot.img of=/dev/sdX bs=1k seek=128 conv=notrunc; sync
|
|
|
|
- Jumper settings::
|
|
|
|
SW7: 1 0 1 0
|
|
|
|
where 0 means bottom position and 1 means top position (from the
|
|
switch label numbers reference).
|
|
|
|
- Connect the USB cable between the EVK and the PC for the console.
|
|
The USB console connector is the one close the ethernet connector
|
|
|
|
- Insert the micro SD card in the board, power it up and U-Boot messages should come up.

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_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,
|
|
which is specific to your flash chip, in Kconfig.
|
|
The flash config is 4K in size and is documented on page 217 of the imxrt1050 RM.
|
|
The default flash chip on the i.MXRT1050 EVK is the S26KS512SDPBHI02 HYPERFLASH.
|
|
|
|
- Jumper settings::
|
|
|
|
SW7: 0 1 1 0
|
|
|
|
where 0 means bottom position and 1 means top position (from the
|
|
switch label numbers reference).
|
|
|
|
- Connect the USB cable between the EVK and the PC for the console.
|
|
|
|
- Use either JTAG or SWD to write `flash.bin` to the NOR. I used Mcuexpresso IDE's GUI flash tool.
