Hi All,

In a design we are using 2 nos. of AVR micro controllers on one board:

The micro controllers are:
1) AT90USB1286 --- Main Micro
2) AT90MEGA1281 ---- Sub Micro

My querie is:

I want to upgrade the firmware of the Main micro controller using USB boot loader and FLIP tool (provided by Atmel).
I have connected the Main micro controller to the Sub micro controller using SPI interface. This is for upgrading the Sub micro controller firmware.
How can I store Sub micro controller firmware code in Main micro controller Flash memory……..
can I define Sub micro controller firmware as Constant data in my main program…..or
does the Flip tool support programming two different images at two different places in Flash memory.

Thanks in advance for your valuable suggestions....

Isn't the FLIP program used for x51 type controllers?

Well, yes, it is. But as an orphan child, it can also be used for AT90USB.
Check out

or search for "flip3".

You can put lipstick on a pig, but it is still a pig.

I've never met a pig I didn't like, as long as you have some salt and pepper.
