Attempted removing each gpu of 3 using the -d 0,1,2 cn_config etc.. Again, window closes to fast to even see an error message.
Please, I know there has got to be just some switch/call that will enable the application to bypass the unsupported device and stay open.
Closing so fast due to 1 piece of unsupported hardware being attached to the machine and giving no error message, that is surely a bug being re-branded as a feature anyway.
You need to learn to use the console/terminal, rather than just double clicking stuff w/ your mouse. Run 'command prompt' (press the windows button or click on the windows icon, and type 'command' - then click on the 'Command prompt' item at the top of the list.) . Change to the directory of the miner software (type 'cd ' followed by path to your miner directory.) Type the name of your start bat file, and press enter. You'll see the output, including whatever errors occurred.
A window closing after the program has exited is not a bug of the miner - it's the way Windows (and most OS') work.
P.S. I used to have a 7950 (and a 580) installed on a 6-vega rig running TRM - worked perfectly fine using -d to exclude those devices.
I know how to use it, when instructed to I do, have, will. Otherwise, why do things the hard way, all the time, its just not logical?
Using the bat file via cmd prompt did "help".
[2018-12-27 14:47:45] Auto-detected AMD OpenCL platform 0
[2018-12-27 14:47:46] Initialize error, unknown platform 03fd
[2018-12-27 14:47:46] Failed to initialize device number 0 (-20)
[2018-12-27 14:47:46] Successful clean shutdown.
'-d' is not recognized as an internal or external command,
operable program or batch file.
So where to from here?
Yeah, not saying all the time - just in situations like yours, for debugging purposes, terminal is your friend. 'teamredminer.exe --help' is also useful. As someone else already stated, try the parameter --platform=1.
The correct platform is detected just fine. It's an unfortunate choice of reusing the term "platform" in the error message. I'm guessing your Tahiti is device zero, but you're not applying the -d param correctly though. It seems to me like it's placed on a new line in the bat file, since the shell tries to execute the "program" called "-d" after the miner exists.
Do these two things and we'll get this sorted: (1) from the cmd prompt, in the directory where teamredminer.exe resides, run "teamredminer.exe --list_devices". Dump the output here and we'll verify the device list. Then (2) dump the content of your start.bat here as well, with any private data anonymized.
If you want to keep the window open when running the miner from e.g. Windows Explorer in a .bat file, add "pause" on a separate line at the end of the .bat.
