Ok, I tried a few different things.
First I tried to run TC with only removing the word "base". I only removed the word base that stood on its own. I did not remove base from
lst=xfbase.lst. From here I left the install directory, TCE:, as the default, /tmp/tce/optional, the app will download, but did not open. It will say firefoxandflash.tcz OK Same white icon with black X. If I change it to /mnt/sdc1 by the 'set' option, the TCE directory reads
/mnt/sdc1/tce/optional
it will download, but it will say firefoxandflash.tcz Failed.
The second thing I tried was removing base and adding tc waitusb=5 tce=sda1. When I did this an interesting splash screen came up. In it is said, "mdir: can't create directory "/tce/optional': No such file or directory Chown: /tce: No such file or directory"
That kind of makes me think it is not making the permanent app file on the USB. I've included a shot of the splash screen. Also, the GUI did not come up in this case. Only a command line.
