Topic: Uploading Firmware Help
I posted this on the Software/Firmware forum but I'll add it here as well since I am looking for some help
I have a mid-2013 SD2 with a Sanguinololu/atmega 644P board. I am working on updating the Marlin firmware in order to finalize the installation of my E3D-Lite6 hotend. In the process of uploading the firmware I continue to get the following error message:
avrdude: stk500_recv(): programmer is not responding
I have worked through the various 'reset' button pushes and I am still getting the same error message.
Anybody work through this issue as well? I have spent the last several nights trying to get this new firmware uploaded and have gone through the whole process listed over on the soliwiki (http://www.soliwiki.com/E3D_extruder) several times.
I have been spending the day looking through the forums for similar situations & tips but haven't come across a solution. My assumptions at this point is there may be something wrong with the bootloader on the ATMega644P, I read a post from wardjr that stated older sang boards didn't come with an installed bootloader? I am pretty sure when I initially set up the printer I had to flash the Marlin firmware to get started, but I could be mistaken (it was a few years ago).
Anyway I was hoping someone may have a few tricks to try before I start going down the process of either re-burning a bootloader to the MCU or buying a new MCU. I guess this could be when I upgrade to an ATMega1284p unit..
Some extra info:
I am running Mac OS X 10.10.5 (Yosemite) & am using the Mac OS X prepackaged Arduino 1.0.5 IDE (linked over on pg 3 of the Solidoodle2-marlin firmware update thread). I am using the Marlin firmware that is also linked on pg 1 of that thread
Thoughts?
Thanks for the help.
