Updating firmware using ISP GO command?

2006-03-09 by Srdan Suka

Hi everyone!

I am using LPC2103 in my project. LPC is connected to server using
RS485 interface (Semi-duplex). Also I have EEPROM memory connected to 
LPC. 
I would like to do this if it is possible:

1. Using my resident LPC firmware, load new firmware to EEPROM memory.
2. Load a small program into Flash into first available sector
   (this program I would like to use to copy new firmware from
    EEPROM to Flash over the existing firmware).

Is it possible to use ISP GO command to execute "Copy proggram" from
Flash to start copying firmware from EEPROM to flash memory.
What will happen it copy process fails and I overwrite firmware at
0x0000 0000 address?
Can I "tell" the bootloader alwayws to start the "Copy program" unless I 
"tell" it that the updating is finishead and the main firmware should
be started?

Has anyone tried this? 

Thanks :)

Srdan
