The releases should work. You should not mix different tools across versions, e.g., the 4.12 toolchain won't work right for 4.11, or vice versa. In general, you should match the RSB and rtems you use, and I suggest you be careful about how you set your paths to avoid installing 4.11 and 4.12 tools in the same prefix. Technically, it may work, but I wouldn't trust it to. > 2) What are the current stable versions of the rtems kernel and rsb?

See: https://devel.rtems.org/wiki/Release/4.11 and I see some bit-rot in https://devel.rtems.org/wiki/Release where dot-release version numbers need bumping... > 3) The *.exe files that get built (e.g. both_hello.exe from the examples-v2 > repo) -- these are full images containing the kernel and application, > correct?

Maybe this helps for Zynq? https://devel.rtems.org/wiki/Boards/Zynq%20-%20Zedboard There are some guides written in the past for raspberrypi and beaglebone. some pointers for beagle can be found through https://devel.rtems.org/wiki/TBR/BSP/Beagleboard including Ben's blog about it, and Alan's (http://alanstechnotes.blogspot.pt/) and Andre's (https://asuolgsoc2014.wordpress.com/) blogs have some nice info about RaspberryPi. > 4) What does <arch>-rtems<version>-run use to simulate the application? > Usually this is tied to a GDB processor simulator if one exists. > 5) The test suite applications seemed to successfully build for the arm > architectures I tried, but when attempting to run them, there is no output. > Depending on the application and bsp, arm-rtems4.11-run will exit with an > code of 48, or 0. sparc-rtems4.11-run produced the expected output with its > test suite applications.

You may like to check out the RTEMS Tester tool: https://devel.rtems.org/wiki/Testing/Tester that contains scripts to run the test suite on a variety of simulators and some hardware configurations.
