I am facing a conflict between fshell USB and appTRK. Since I've installed appTRK (from QT creator), Fshell USB is complaining "Opening port ACM::1 returned -21" and "Failed to create console VT100 (-21)"
I use appTRK for using runondevice.exe in order to install application from some python script on PC.
Using Fshell, I only succed application installation from hyperterminal, not from python.
Any suggestion ?
Thank you
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
-21 is KErrInUse, so the problem seems to be that both appTRK and fshell are trying to use the same serial channel. Most devices only have a single spare serial channel for debug use. I know Tom has been working on a serial multiplexer for fshell, so he might have a white rabbit he can pull out. But in the absence of that, you'll need to not run both appTRK and fshell at the same time. Note, you can use the 'ymodem' command to transfer SIS files to the device and the 'swi' command to install them, if you want to just use fshell.

Did I say KErrInUse? Should have been KErrAccessDenied. Probably a similar meaning in this case though…
