Notes: Navigate to the directory that has the file you want. You will need to enter the USB port you are actually using.To find your serial port in Mac/Linux you can run button on the Tiny G board. You can tell that your Tiny G is in bootloader mode by the flashing red Spindle CW/CCW light.You can also enter bootloader mode by sending To transfer the firmware update to your Tiny G you need to use a program called avrdude.
You can get the avrdude prebuilt for your platform here from the code branch your choose (Tiny G Firmware File) you will need to do so.
In 99.9% of cases you will want the hex file located in the master branch.
The file is found here: Synthetos Download Page Save the hex file in some known directory that you can get back to.
If you have not done so you need to return to the firmware updating explained section above and selected a Tiny G firmware file to download.
There are 3 ways to update the firmware on your Tiny G.
The first two methods is to use the bootloader on Tiny G along with avrdude.
This method requires no special hardware programming devices, only the Tiny G USB cable.
The third method is using an AVR Programmer (such as an AVRISP MKII programmer).
This method requires more work and is not described here as of yet.
It is also not needed if you have a bootloader loaded on your Tiny G.
