I took the DM368 off a bord but Im yet to find the other bot pin required to boot from the UART. The pin you found is one of them, I might probe inside the can again to see if I can find the other one.I assume that there is a standard pinout,
Maybe I'll connect later and check
Karma refusing to pair - Reverse engineering investigation
- Thread starter Argiris
- Start date
If I remember correctly, then the second pin for starting to download via UART is connected to ground, and this only means one thing, that it is connected to the nearest ground on the board, most likely gnd it is located directly under the DM368
This can only be known for sure by removing all components from the board and sanding off its layers, as is done during reverse engineering of PCB boards.
Is this justified?
Or is this already a sporting interest?
This is exactly why I went the route of loading from SD card.
Yeh , I get it, if there is only one pin exposed and that is for SD card boot then that is the method that needs to be used. If we were able to find the second pin for UART boot then some of the complexities around the SD boot would be removed from the process (soldering on small pads, needing a micro SD slot). These two things make the process hard for some people.

Am Ende ist noch ein Log über STMDBG UART XI2C.

I assume that the firmware as already on the controller as I dont think the backend GoPro server has been operational for a while.
I don't know if GoPro servers are working. But in the controller, the firmware is stored
You can also get these firmwares by going to your account on the GoPro website

Great, lets hope they are useful. It could be worth checking with GoPro to see if they will be releasing an update to the WMM but as they no longer support the Karma more than likely they will not be.
did you get clipping the micro sd card to the board to work ? I tried it and it failed to boot off it. I assume the pins just arnt protruding enough to make contact?
Have a look at my controller image here
It should have maps for Canberra Australia in it. If not let me know and I will see what else I have.
Alle 8 Kontakte danach auf Durchgang prüfen (wenn 9 Kontakte) 9=Masse
Thanks, but this is a dump of the "system" partition.Have a look at my controller image here

I assume that the maps are saved in the "data" or "gopro"(less likely) partition
