README

 
The Bootloader upgrade proccess from UART involves 3 binaries.

1) BUILD the loader binary. This is the binary that runs in 452, 
reads from UART and writes the actual bootloader to flash

  cd loader/
  make sc14452loader

2) Build the actual bootloader

  cd cr16boot/
  make sc14452reef_config
  make  all
  make image_452

3) Build the host PC application that communicates with UART.
  cd uart/host
  Make sure #define MODEMDEVICE "/dev/ttyS0" corresponds to the actual UART device.
  make all
  if you want to run binary from Windows use WinHost.tar
  
3a) Build target UART application
    cd uart/target
    make all

4) Make sure 452 is in boot mode: Short UART TX with GRND (the 2 pins in uart 
    connector edges) while you power ON the device. The UART RX led will start blinking.


5) Please copy all files needed to flash into one place:
    a) uart/host/uartfp
    b) uart/target/452fp.bin
    c) cr16boot/image452.bin

   You can flash target with command:

    On linux host use following command:
	./uartfp 452fp.bin image452.bin
	
    If running in Windows host type:
   uart.exe  31  452fp.bin image452.bin    (31 is COM port number)
   

You should see the following output
