Problem after attempting to upgrade firmware

hk Aug 13, 2013 #

I just received a tinyg V8. I wanted to connect via tgFX but it said I needed to upgrade the firmware. I attempted to upgrade and got this response..

C:\Users\Jason\Desktop\avrdude>avrdude -C avrdude.conf -p x192a3 -c avr109 -b 11
5200 -P COM10 -U flash:w:tinyg.hex

avrdude done. Thank you.

I have attempted several different tinyg.hex files and none seem to do the trick. After doing some research it looks like I have to get an mkII programmer and set the lock bits to nolock. I had assumed when I purchased this that I would not need the mkII to be able to upgrade firmware otherwise I would not have attempted the upgrade. Now every time I power up my tinyg I just get the flashing D5 (SpDir) light. I cannot seem to do anything else with this and am now kind of dead in the water. Can anyone help out?

You do not need to set the fuses. Or should not.

If your goal is to use tgFX you need to right click save this file.
https://github.com/synthetos/TinyG/raw/edge/firmware/tinyg/default/tinyg.hex

That is Edge. Normally you will always use master for tgFX support. However, I pushed past master on accident. Edge will be pushed to master shortly. However as of today (Aug16 2013) Edge works with tgFX.

Try that file and we can see if that fixes things. If not you can send us the board back and we can get you a new one. Your fuses should be set right. However, mistakes do happen. We will get you working.

Sorry for the late reply I am watching this thread and should be much faster to reply.

Thanks,

I did attempt to use edge with a similar result. It does not appear to accept any.hex. It always ends with a similar. I have ordered an mkii to try and resolve this issue.
