I want to write procedure that upgrades code in internal flash. It will be full upgrade of flash with executing mass erase command, so I should copy upgrade procedure to ram, execute it from ram and upgrade program.
And I have questions:
1. when I copying function to RAM, i copying data from flash address to ram address, but how detect size of function (it will not be only one function but more functions, so I want collect them...)
2. how to execute program from RAm after copy ? simple jump ?
3. how tell the linker to locate pocedures in flash at specified address ? (I want them to be inside first page of flash)
4. how tell the linker to locate some constants at special flash address ? (for veryfing flash contents)

with best regards,
