Optiboot and AVR Studio incompatible #27

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Burn optiboot_diecimila.hex in Arduino Duemilanove
2. Replace boards.txt in Arduino IDE. Test upload - OK on 115200 baud
3. Start AVR Studio, select STK500 programmer and port, press connect - FAIL.

What is the expected output? What do you see instead?
I've expected Optiboot to work with AVR Studio as STK500, because the protocol 
seams the same and now speed 115200 baud is the same.

What version of the product are you using? On what operating system?
Arduino-022, AVR Studio 4.18 SP3, Win XP SP3.

Please provide any additional information below.
Maybe it is not a bug but a feature. But it'll be really nice to be able to 
flash arduino from AVR Studio even if optiboot will grow in size a little.

There are a lot of ways that optiboot is incompatible with a real STK500; 
optiboot only supports a relatively small subset of the STK500 commands needed 
to support uploads.  (I didn't think it would work with the old bootloader 
either; neither supports the "universal" spi interaction command...)

This is going to be a necessary limitation of a really small bootloader.  Since 
AVRDUDE works on all platforms, I don't think we'll try to fix it.
