I have an original Raspberry Pi B and haven't been able to get PiCore to work on it. I have tried both 14 and 15 versions and get the same results. I created an SD card with the image and it will boot fine. I followed the instructions in the README file to adjust the size of the partition, etc. With that, it works fine as a non GUI system. However, running startx revealed that the GUI wasn't installed. When I ran tce-load -i TC.tcz it didn't find it and I found I needed to download the .tcz file (I didn't see the -wi until later). I did find some instruction how how to download the .tcz files to the "Optional" directory which I did. Then I rand tce-load -i TC.tcz. Id started out fine, but ended up getting errors resulting from a missiong desktop.sh script. That was apparently supposed to be automatically deployed to the /usr/bin directory, but wasn't. I have run the above steps multiple times, and also tried version 14 in addition to 15 with the same result. After some playing and manually installing the flwm_topside extension the desktop.sh file appeared, so I saved it off and started over. This time I manually copied the desktop.sh script to /usr/bin before running tce-load -i TC.tcz. Then it installed with no errors. After launching the GUI with startx, I found that the only application that would run was the terminal app. The rest of the icons in the dock at the bottom of the screen did nothing when I clicked on them, including exit. The popup menu options also did not work. It appears that something is still missing in the installation. Any suggestions would be appreciated. I should mention that I downloaded the armv6 version of everything I used.
