RE: [avr-gcc-list] AT90CAN128 bootloader

[Larry Barello]

I took Jason Kyle’s boot-loader and reworked it to fit in 512 words.  A version that should be relatively easy to modify for your needs can be found in the files section of Yahoogroups “avrrobotcontrol”  You will need to sign up for Yahoogroups to see it & download.  it is a stand-alone program using GCC.  You load it into the target chip and then use the old fashion STK500 protocol to communicate.  With a 16mhz crystal you won’t be able to use “STK500.exe” as that is fixed for 115.2kbaud and you can’t get that baud rate with a 16mhz crystal; use AvrDude, which works fine.

 

The specific loader is for a mega16, but many of the classic chips can be specified (look at the source) and new ones easily added.  For the mega128 the code is fixed for USART1, but again, easy to change.

 

Cheers!

Subject: [avr-gcc-list] AT90CAN128 bootloader

 

I know this has been asked somewhere before, but is there a bootloader that is easy to implement for the AT90CAN128?

 

I would like to have the ability to upgrade firmware on my device through serial port, I found this link and it looked ideal except I am using UART0 and 16Mhz which is not support.

Maybe someone has a how to on including the bootloader in my sources?

 

Thanks
