Good day!

How do I burn System memory of STM32F407 via OpenOCD?

I do:

dump_image old.bin 0x1fff0000 0x7800

load_image program.elf 0

It says:

21366 bytes written at address 0x1fff0000

But then

dump_image new.bin 0x1fff0000 0x7800

diff old.bin new.bin

says they're equal...

Help, please! Thanks!

It is ROM/OTP, you don't get to change it.

So, is System memory (30Kb at 0x1fff 0000) read only? And there is no way to program it? Nor programmatically nor via OpenOCD?

Thanks!

There is no provision for user programming.
