E3Dv6 on Solidoodle Press (Page 11 of 21)

so, soldering my TinyUSB now. 

where do you plug this thing into the board on the Press?  i see two empty 6 pin plugs on the board.

also, for those going the USBtiny route.

in this thread is how i installed the drivers necessary for the programmer.

it seems as if the link on adafruits website is dead for these drivers.

I see. I will try and make sure its connected properly tomorrow. Then attempt to flash it. When the usbtiny is connected to the board is it normal for the green light on it to turn off?

Also. Before running this in avrdude

avrdude -c avrisp -b 250000 -i 10 -p AT90USB1286 -P /dev/ttyACM0 -F -U flash:w:Solidoodle_Press_Modified_Firmware.cpp.hex:i

Its mentioned to navigate to the folder that the modified .hex file is in. Is that done in the command prompt window using avrdude?

Ok. So. I would replace that with....for example here...

cd C:\Users\Zerb\Desktop\HID Bootloader

If that was in fact where the modified hex file was on my PC.

alright.  before i attempt this i just want to make sure ive figured this properly here. 
first off, i assume that viewing the board this was the 6 pin header i want to connect the usbtiny to is the one on the left hand side of the picture labeled 1

so, i plug the connector in like so, no jumper in JP1

in avrdude, to make sure i have a proper connection i type in

avrdude -c usbtiny -p usb1286

to which i get a response of
avrdude: AVR device initialized and ready to accept instructions.

if i place the jumper in JP1 and type in the same command as above i get the same response. so im assuming im on the right track here. 

now for the flashing firmware from what ive read i assume i would type.

avrdude -c usbtiny -p usb1286 -u flash:w:C:\Users\Zerb\Desktop\Solidoodle-Press-E3D-v6-master\Firmware\Prepped for E3D v6\HEX:i

i would just outright ask for someone to tell me how to do this, but i figured i would at least go as far as i felt comfortable and post up here before i actually went ahead and tried to flash anything.

Did you order a USBTINY as well?

I haven't tried to flash anything because I'm still not sure if my above process is the proper way to do it and I don't want to brick anything.

Awesome. Well if you get it to work let me know what code you use in avrdude to flash the board. Again, I'm totally new at this so I'm just trying to make sure I'm doing this properly.

Anyone who used the AVR programmer. Did you need to set the fuses first and load a boot loader prior to flashing? Or did you simply just flash the firmware?

I see this is the method that people used on the older solidoodle boards. Just wondering If this is the same or not.

//Set fuses
avrdude -c usbtiny -p at90usb1286 -U lfuse:w:0xde:m -U hfuse:w:0xdb:m -U efuse:w:0xf0:m
// Flash bootloader
avrdude -c usbtiny -p at90usb1286 -U flash:w:BootloaderHID.hex:i
// flash firmware (not necessary, best done with USB)
avrdude -D -c usbtiny -p at90usb1286 -U flash:w:Solidoodle2_6142013.cpp.hex:i

Make sure that the orientation of the ISCP connector is correct. And you have the correct programmer chosen in the command line.

Not understanding why this is so hard for some folks.

Dream-Cypher, You were able to do it in Windows right? Did you have the same issues as the other folks here? It seemed like it worked as expected for you.

You and me both! 

Alright, doing this from the RPi.  I hooked up the ArduinoISP via USB to the RPi.

using
avrdude -c avrisp -p at90usb1286

it returns
avrdude: ser_open(): can't open device "/dev/ttyS0": No such file or directory

That's about as far as I could get on the RPi.

and now, seems as if bad things just happened

realized i forgot the :w: between flash and the :Solidoodle_Press_Modified_Firmware.cpp.hex and now it looks like ive totally fucked myself because the chip seemed to erase, but not flash the new firmware, unplugging everything and turning the printer on i now have zilch for connection.   printer powers up, but no communication.

avrdude done.  Thank you.

i put the file directly in the Computer>Local Disk (C:)>   folder.
