Easy to do if your OS is running from RAM. In case its XIP, you can
write an app which is loaded completely into RAM. This app should read
the update, turns off interrupts and erases/writes to flash directly.

Hi All,
Are there any ideas as how I can run OS updates to a custom device after it
is released? For example, at what sequence would the updates have to be
written? I am thinking that it would have to be done straight after the
bootloader startup and before the kernel address is loaded/jumped to. Is
this correct? What would need to be done? I am unclear how updates are
performed across a custom device. Any ideas?
