CheckSum for different Power settings in Global Resources

Question: For the same application code, if I change the power setting between 5V and 3.3V, will the Checksum of the device change?



Yes.  For the same application code, the device checksum will be different for 3.3V and 5V operations.

Based on the Power setting parameter in the global resources, the boot.asm code will be modified.  As the device checksum is nothing but a 16 bit addition of all the code area, the change in boot.asm will result in a different checksum for 5V and 3.3V operations.
