Topic: Black bars on my LCD

I think I softbricked the printer while trying to use Repetier. I get black bars when I turn it on. When I try doing anything through Arduino, I get:

" Sketch uses 10,380 bytes (1%) of program storage space. Maximum is 524,288 bytes.

Erase flash
Flash page is locked"

I must have an upgraded board because there are no jumpers or the 3 buttons I see on other boards.

My computer still recognizes the printer as "Bossa Program Port (COM8)" in my Device Manager.


Any help is appreciated!. Thanks

Re: Black bars on my LCD

I think I already replied to your comment on my video, but yeah it will be an easy fix using the bossac flashing tool through command line.

Re: Black bars on my LCD

You did. I've posted this in a few places hoping for help. I installed the Bossa flash programmer, but while it recognizes my printer is on a port it tells me "Could not to device on COMX". I tried changing COM ports, but same outcome.

Thanks for your help, by the way.

I also posted in Voltivo with pics of my board.

Re: Black bars on my LCD

I have the same board (no jumpers on jp1) I used a paper clip to erase the firmware and BOSSA program port installed.
When I uploaded the github/repetier on the arduino sketch an error message: 'Timetick_Configure' was not declared in this scope. black bars appeared on lcd and now stuck at this point.
   
My Bossa flash programmer won't connect either.
I'll keep updated if I ever figure this out

Make sure you have the Arduino Due (native usb) selected in arduino. That should fix the problem. HTH

Re: Black bars on my LCD

yes thank you w34, that worked and downloaded the firmware. It didn't unbrick my printer though, only heated up my bed and extruder. (maybe a pinout problem) the variant file is confusing because it only uploads test off the zip file on the sketch. Do we still need  the sd card?
I checked the device manager and it can't find the necessary software. COM15 disappeared until I erase the chip again. In the manager above ports shows: other devices with a (?)/arduino due is cautioned(!). I'm pretty sure I downloaded all the right drivers from atmel

Re: Black bars on my LCD

ok timr,

You have to have the variant file replaced or you will likely destroy your main board. variant is not a sketch is is a board definition.
I think you will be best off using command prompt and flashing the pre compiled hex file.

https://github.com/bgm370/dav10

download zip and extract to a folder, Variant will be in that folder. also will be repetier-0.91-alpha-davinci10.bin   

the other form already has a couple posts on how to do the bossa flashing
