Wouldn't disabling the flash readout protection erase the custom boot loader that might be stored in the main flash memory?

Where's the CRC and the size of the whole firmware application stored whenever a new application is flashed on to the System flash?

Does the controller perform a CRC confirmation check before running the application to check if the firmware is corrupted? If so, where does this happen; in the bootloader or the application itself? What does it do if the CRC turns out to be wrong? S...
