I've been using DES bootloader from atmel app note for a while. The problem is that occasionally my mega8 locks up. It will still accept and complete upgrade, but the application will simply not run any more. I have to re-program the boot loader to make it work again. Does anyone have experience with this kind of behaviour? Someone on avrfreaks hinted that there was a problem and linked to a non-existing thread. The fuses are setup so that no LPM/SPM is allowed in the boot section. Any clues? -- Siol ------------------------------------------------ Rather than a heartless beep Or a rude error message, See these simple words: "File not found."

I find it hard to believe that noone uses the DES encrypted bootloader. -- Siol ------------------------------------------------ Rather than a heartless beep Or a rude error message, See these simple words: "File not found."

No bootloader at all in any of my AVR products (at the moment) - they are factory-programmed once over JTAG or SPI. I'm going to add a bootloader to one of my devices in the foreseeable future, but it will not use any kind of encryption, and it will be loading the upgrade code off a removable flash media card.
