Part Number: OMAP-L138
Tool/software: Code Composer Studio
Maybe someone has already posted this particular solution to the problem, but I wanted add this in case it helps anybody else.
I installed the Linux version of CCS 10.1 on a Dell Inspiron running Mint Linux 19.3, very similar to Ubuntu 20.04. The installation ran with no problems until I started it and got the "Failed to create the part's controls" message. After trying all the suggested solutions I could find from previous posts, I realized that I had neglected steps mentioned on this page:
software-dl.ti.com/.../ccsv10_linux_host_support.html
That doc advises you (under Ubuntu distributions) to "install dependent libraries: sudo apt install libc6:i386 libusb-0.1-4 libgconf-2-4 libncurses5 libpython2.7 libtinfo5" (presumably before CCS install). I added them after installation, and as soon as I did the Resource Explorer window replaced the error message. So there.
One previous post advised using ldd on the .jxbrowser-chromium-lib directory to find missing library dependencies. Before I found the solution above, I ran ldd on the browsercore64 executable, and it reported not finding libbrowsercore64.so, even though it was listed in the directory. Strange. And ldd still reports that even though now everything is working OK.
Anyway, good luck to all of you installing CCS.
