I found the location to download the toolchains. It looks as if the one I want is:
NXP_GCC11-4_eARMv7_gf703eb2-LINUX
But it says that it's a .bin but when I run it either with "bash file.bin" or "chmod +x file.bin; ./file.bin" I get the error below.
Why would Java be in the mix? Is there tarball version of these tool. There is a tarball for the GCC tools but I assume this not the NXP adapted compiler (which I need to build the RTD).
