Firmware update from target MCU
I wish to use a Freedom KL25Z board in a product as a USB input device and plan to cover over the SDA port in the casing. This leaves me with a problem on how to do firmware upgrades in the future. Ideally I would like to enter the device into an upgrade mode where the devices flash is exposed as a MSD just like through the SDA port. Unfortunately to implement the mbed MSD class I need to expose the flash at a low level while the mbed libraries only expose the flash at the file level through LocalFilesystem.
Can anyone suggest a firmware update solution that could be done from within the target MCU?
