I want to customize System memory UART Boot-loader and will use as Flash Memory Boot-loader. Please share the System memory Boot-loader Source code or the link where it is available.

Regards

Even if you get sources, you cannot patch the system memory bootloader. It is not rewritable.

I don't want to rewrite it in system memory. I will use as flash memory bootloader .

You are on the wrong track.

Forget about the ROM-based system bootloader. Even if you pay ST dearly, it is of no worth for your endeavor.

You want a second-stage bootloader, which is just viewed as a normal application during system start.

There are plenty of examples available for several STM32 types, not sure about L071.

I submitted an "Idea" to ST, asking them to publish bootloader source code.

If you're also interested in the bootloader sources, be sure to vote on the idea: https://community.st.com/s/ideazone#0873W000000PAwtQAG
