Attempted to update firmware, Bossa will not work.

Just write and verify, I don't think I've ever used read. Don't forget to hit the reset button again after verify has been completed.
At one point I had completely swapped the buttons in my mind. When I thought I was pressing reset I was actually pressing erase. So make sure to check the labels on the PCB for each button.

Ok that is what i figured. I'm fairly positive I have been clicking everything correctly. I'm worried perhaps the LCD screen is dead. It doesn't light up at all when connected to power, pre or post reset. I've checked all the connections and they seem alright. Should it light up even just white at any point in this process?
-
Are you sure you have the correct firmware for your board? I have seen it not light up at all if I have used the wrong version before. I was still able to reflash to the correct version afterwards.
Have you been able to successfully flash the firmware using this computer in the past? It's possible the USB port isn't providing enough power.

That screen looks OK to me. What happens when you press Write? If it reports success, what happens when you press Verify?
Check the size of the downloaded file. It should be around 181kb.
-
fairly positive. I know the paneldue is a V3 and the screen is 5 inches. From upper left to bottom right corner it is 5 inches.
This is my first time programming it. I had "success" when I tried the 4 inch firmware in that it lit up, however it the screen mirrored horizontally for half the screen and the other half had broken rainbow lines on it.

This is the screen for write:
Here is verify:
And here is the file I am uploading:
-
Your downloaded file is 256kb long, whereas the official release binary at https://github.com/dc42/PanelDueFirmware/releases is 181kb. As the processor has only 256kb of flash memory, my guess is that either you have a corrupt file, or you have appended your own splash screen to the -nologo version and in doing so made the file slightly too long because your splash screen doesn't compress well.
-
That was it! I didn't add a splash screen (don't even know how to) so it must have corrupted at some point. I'm very glad this is solved though. Thank you!
-
I'm glad you solved it. In RepRapFirmware we do a quick check on the firmware binary to avoid installing an obviously bad file, but unfortunately Bossa can't really do that because it has to be more general.
-
Gotcha. I'll keep an eye out for stuff like that in the future. Thanks again.
