all,
I have used an112 to implement in-circuit firmware update with the serial port.
I am not having problems updating the firmware (i.e when only the bootloader is present). But the next time, when I call the bootloader using a function pointer from the application code, although the code executes I am getting 'checksum error' .
However if I reset the system (power down and up) after updating the firmware with bootloader, there is no problem in loading a new hex file.
can some one help me on this ??
regards
