Installing ti-sdk-am335x-evm-05.06.00.00-Linux-x86-Install leaves me with a number of 0 byte files in the root directory, including the setup.sh and Makefile:
-rwxr-xr-x. 1 ken ken 0 Dec 16 14:52 Makefile
-rwxr-xr-x. 1 ken ken 0 Jan 14 20:38 Rules.make
-rwxr-xr-x. 1 ken ken 0 Dec 16 14:54 setup.sh
I've downloaded it twice on different machines and have the same result...
