Hi,
I would like to program the lpc2138 flash (on board) to a new firmware by using
only the i2c.
Can it be done? Should I use the IAR-EW “intel-extended” output?
If so, can anyone please tell me if there are any specific settings I should
take care of, and which address should I start programming from?
Thank you.
firmware upgrade using I2C only

When you say, "to a new firmware", do you mean that this lpc chip was already programmed by another means (i.e. jtag) and you wish to update the current firmware to a new firmware ?
When you say "by using only the i2c", do you mean that the lpc is a master (i.e. program received from an external I2C memory) or do you mean that the lpc is a slave, to be programmed by an external I2C master device ?
or do you mean a blank lpc to be programmed by an external I2C master device ?

Sure, it can be done. But you would have to write the code to do it using the IAP (in application) functions provided by the boot loader.

you will be needing to write a boot loader for it and a mechanism to jump to that boot loader without manually restart.
In that boot loader write I2C code with IAP code for the controller
