so i am using the arduino mege for this , that one has a good decent amount of program memory . now here is what i need . i want to reserve 60kb of program memory (flash memory) . i want to be completely empty . i managed to get the mega to read at a high speed off of an sd card . so can i reserve the space , then write data to it from the sd card ? the execute at the beginning of the 60kb space ? .
it should be independent from the other main program . there is a command to write pages "SPM - Store Program Memory" and i think i can the program to execute a an exact address of the program memory but can the whole thing all togeather work ?
