Bootloader from Flash

Post by AJ Smith » Tue Jul 29, 2008 8:14 pm


A buddy of mine is using an LPC2148. He is using USB and is trying since days to implement an USB bootloader but with no success. His bootloader is on the Flash, NOT the RAM. He is using the IAP function to start the bootloader. This seems to work so far. He can delete sectors BUT as soon as he wants to write to the Flash the Flash is unlocked and he can't write to it.

Is the reason maybe that with IAP you can't write to Flash because
it's running from the Flash?

Any ideas why this is not working?
