MIMXRT1170 how to remove uboot in QSPI flash

yunlian — Tue, 20 Sep 2022 16:44:34 GMT

Hi,

I tried to install the BSP from emcrafts to install linux on the board.

Now the devices uses the uboot on the QSPI flash to boot to linux every time. I want to go back to

the default system so that I can play with the MCUXpresso SDK. But I don't know how to do that.

The emcrafts people told me "bringing the board back to the factory state is just erasing U-Boot in the QSPI Flash", So my question becomes how to access and remove files in the QSPI flash.

Thanks

Hello!
I hope you are well.

You can erase the content from the flash by using MCUBoot Utility: GitHub - JayHeng/NXP-MCUBootUtility: A one-stop boot utility tool based on Python2.7+wxPython4.0, it can help you get started with NXP MCU (i.MXRT,LPC,Kinetis...) secure boot easily | 恩智浦MCU安全启动一站式工具（研发模式），既可独立使用也可配合MfgTool或RT-Flash，助你轻松入门安全加密启动

Please note that to use you need to set your board in Serial Downloader mode.
If you have more questions do not hesitate to ask me.
Best regards,
Omar

Thanks,

I found a doc in https://community.nxp.com/t5/Blogs/Overview-of-using-the-MIMXRT1170-EVK-with-MCUXpresso-IDE/ba-p/1241069

And I erased the uboot though the IDE.
