Hi Andy Dong,

Please refer to the NXP official flashloader:

Flashloader i.MX-RT1050

The source code can be downloaded from the SDK, please go to this link:

Welcome | MCUXpresso SDK Builder 

Choose the EVKB-RT1050 board, in the middleware, please select  mcu-boot:

The flashloader already contains the SD card boot, please refer to it.

If you still have questions about it, please kindly let me know.

Have a great day,
Kerry

Hi Andy Dong,

    If you also download the flashloader:

https://www.nxp.com/webapp/Download?colCode=IMX-RT1050-FLASHLOADER&appType=license 

There has some document about it.

  But, about the detail usage, if you are using the official MIMXRT1050-EVKB board, please download the MCUBootUtility tool from this link:

https://github.com/JayHeng/NXP-MCUBootUtility/releases/tag/v1.4.0

The software user manual link is:

GitHub - JayHeng/NXP-MCUBootUtility: A one-stop boot utility tool based on Python2.7+wxPython4.0, it... 

Wish it helps you!

If you still have questions about it, please kindly let me know.

Have a great day,
Kerry

Hi, Kerry Zhou

I know the MCUBootUtility

But I think I didn't express my demand clearly.

I will put the latest application (image) in SD card 

Everytime when I power on the board, the flashloader ( bootloader?) will check the version of application

If it's not the latest one , then flashloader will update the application from SD card to dataflash(maybe Nor flash or SDRAM).

Just like the firmware upgrade. Can you tell me how to implement it ?

Also, In MIMXRT1052xxxxB -> bootloader_examples 

led_demo_evk_ram, led_demo_evk_flexspi_nor, flashloader, 

These three examples don't have any readme.txt 

I don't know what these three example exactly do. Can you explain to me ?

Thanks!!

Best Regards,

Hi Andy Dong,

    So, you need to read the flashloader source code carefully, you can boot from the app, then check the app version, then decide update the app or not.,about the SD card  and nor flash driver, the flashloader already contains it, you can check the code carefully. You need to modify it by yourself.

led_demo_evk code in folder:

SDK_2.6.1_EVKB-IMXRT1050\boards\evkbimxrt1050\bootloader_examples\demo_apps

is just the app code.

The flashloader code is:

\SDK_2.6.1_EVKB-IMXRT1050\boards\evkbimxrt1050\bootloader_examples\flashloader

So, if you want to write your own flashloader code, you need to refer the flashloader project, not the led, led is just the app code.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Have a great day,
Kerry

Hi, Kerry Zhou

One more thing I want to check.

In Flashloader_RT1050_1.1\Tools\mfgtools-rel\Profiles\MXRT105X\OS Firmware\ ivt_flashloader.bin

this .bin is generated from this Project ( \boards\evkbimxrt1050\bootloader_examples\flashloader ) ,right?
