Hi all,

I would like to know if it is possible to upgrade the firmware on a application based on ST7 by using an RS-232 link (via SCI controller on ST7 MCU).

If possible, do you know an application note about it ?

Thanks in advance.

You can copy the data passed by PC in the RAM, call embalgo routines and pass this data.

The usage of the software is given in below application note:

The flashing routines can be found from:
