Hello Everyone,
I had some trouble uploading sketches to my arduino fio wirelessly. According to my search on the net and also according to my earlier post (viewtopic.php?f=13&t=29199&p=130579#p130579) I have learned that I need to reset the bootloader.
So can some one please help me out as to how do I reset the bootloader? I would appreciate if some one can give me a step by step instructions or point me to a good link/tutorial.
Thank you.
The Arduino and other boards normally have wiring so that when the PC you use to download wishes to do so, the downloading software tool asserts a certain serial port contol line (DTR as I recall). That is usually wired such that when the software tool toggles the line, the AVR CPU is reset. That causes the bootloader to try to accept a download of new code. If the download does not commence, the bootloader in the AVR will give up and execute (again) the code already in the flash memory of the AVR. This might be a time span of a second or less.
Hi,
Thanks for the input. I get the idea of the bootloader. But my question is how do I reset the bootloader,since my bootloader keeps executing whats in the memory and is not letting me upload a new sketch.
Did anyone ever resolve this issue for you? I’m having the same problem and I can’t find where to download the bootloader…
thanks in advance!
