how the F411 to use a bootloader?

[spxwh]

I'm using the F411 chip and want to use a bootloader, but the code on the website only provides compilation options for the F407 bootloader.
Can I use the F407 compilation options? Are they compatible? Or where can I download the SD card bootloader code for modification?Thank you.

It depends on which variant. Best would be to copy and modify STM32F411CEUX_FLASH.ld to match the booloader.

Or where can I download the SD card bootloader code for modification?

From github? Try this search.
