-/bin/ash: ./Test_app.elf: not found

I'm attempting to run the Xilinx SDK Hello Word example on a MicroZed (7Z020), using SDK 2017.4 on Windows 10.

MicroZed is running the as delivered Linux OS:

zynq> uname -a
Linux 192.168.1.10 3.8.0-xilinx #2 SMP PREEMPT Thu Jun 13 10:25:52 PDT 2013 armv7l GNU/Linux

I followed the How to create Linux applications video https://www.xilinx.com/video/hardware/how-to-create-linux-applications.html and get as far as launching the executable but then get an error at the Eclipse console:

zynq> /tmp/Test_app.elf

-sh: /tmp/Test_app.elf: not found

Running from a Linux shell produces the same result:

zynq> ls -la
total 33
drwxrwxrwt 2 root root 60 Jan 1 02:45 .
drwxr-xr-x 18 root root 1024 Jan 1 02:03 ..
-rwxr-xr-x 1 root root 32008 Jan 1 02:38 Test_app.elf
zynq> ./Test_app.elf
-/bin/ash: ./Test_app.elf: not found

Toolchain is 'Xilinx ARM v7 GNU/Linux Toolchain' with tools:

ARM v7 Linux gcc assembler
ARM v7 Linux gcc compiler
ARM v7 Linux g++ compiler
ARM v7 Linux archiver
ARM v7 Linux gcc linker
ARM v7 Linux g++ linker

readelf shows:

readelf.exe -h Test_app.elf

The only possible issue I see is that build commands are 'arm-linux-gnueabihf-gcc' when I was expecting 'arm-linux-gnueabi-gcc'.

I tried switching to 'Xilinx ARM GNU/Linux Toolchain', but then get build errors ''arm-xilinx-linux-gnueabi-gcc' is not recognized as an internal or external command'.

Do I need to select a different Linux toolchain or change some other configuration?

Thanks
