I have a problem with my application: I developed an update procedure that recive the new firmware, store it in sdram and then write it to flash memory.
It worked fine until now: I noticed that when my .ldr file becomes larger than about 635KB the procedure work fine but very slow (20 minutes against 1 minute). I see that each falsh sector is cleared and written very slowly.
I suspect some problem with memory configuration of my project, but I am not very experienced about that.
I hope you can give me some advice.
Thanks in advance
