another question is how can SBL read the bootable image in SD card?

There is SDK sdmmc driver integrated in SBL/SFW.

You have to implement an 2nd bootloader to support SD OTA in you application.

You can refer to below OTA reference from NXP SE team, it includes SD OTA.

Hi,

I have read the prj(sbl and sfw) ,  my question is not to use SD to update apps ,  but use some media(such as usb or net) to update app in SD(the boot device)

[jay_heng]

You can refer to \SDK_2.12.0_MIMXRT1170-EVK\boards\evkmimxrt1170\bootloader_examples\flashloader demo, it contains what you want (data from USB HID to SD Card).
