Hi everyone

I am playing about with danni's bootloader for Attinys and Megas

I have managed to upload the bootloader onto my Mega32

I have even managed to connect to the bootload and upload a hex program. But i can do this just once. I cannot seem to envoke the bootloader the second time. Reseting the device is no use.

Should i change the fuses after uploading the Bootloader to the mega32?

Right now my fuses are BOOTSZ set to 512 words
and BOOTRST cleared.

Thanks Rodney

It need to be checked for the micro to go into the bootloader after reset.

Bootloader FAQ explains about BOOTRST and other stuff - as you'll read there my opinion is that BOOTRST must always be set when using a bootloader as you cannot rely on an (intact) app being located at 0x0000
