GT2560 V3.0 Pinout or how to burn bootloader

Post by BamBam » Mon Oct 08, 2018 10:12 am

Hallo together,

During a Firmware upload I lost connection...
Now the board is just beeping und im unable to upload any firmware.

How can I burn a bootloader on the board?
Where do I need to connect to?

Thank you
Using an A10

Hello.
:mrgreen:

To do this you will need a programmer, e.g. USBASP.
Place photos of the controller board and I will do my best to show you in detail what and how.

I have the same problem and have asked Tech support for help and got no reply! I mistakenly tried to load a Hex file WITH bootloader and now have no communication with the printer. It seems from everything I have read that the GT2560 Rev A & B had a SD Card connector you could use to flash a new bootloader but the V3 has no such connector. I could really use some help here! :oops:

Hi
:mrgreen:

Photos are of poor quality ... :(
Despite this, I saw one unsolderable connector on them. It is located next to the description of the controller board model. ;)

I suggest to check with the continuity tester where the leads are connected.

I was hoping for a little more than that, like maybe someone that has flashed a bootloader to this board and can share the hookup.

But thanks anyway.

Hi
:mrgreen:

If this connector does not have the appropriate signals, there is no other output, you have to solder the wires to the terminals of the SD card slot :!:

there is a full guide here on the forums on burning a boot loader to the gt2560 V3 should try searching before re-posting something that has been documented.
also i can confirm i have personally burn boot loaders to several gt2560 V3 boards and it works i even made a breakout board to make it easy.

Instead of writing this long sentence, You could have written the link to the full guide. This would have been much more helpfull (even when I agree, that it is always recommended to use the search, but sometimes, you don't use the good search words). ;)

This is the link, I guess You are talking about: http://www.geeetech.com/forum/viewtopic ... 98&t=61850
