IMX7 - ARM cortex M4 development IDE for Linux

[SVC2]

Hi,

I am trying to setup a development IDE for Linux to develop application for the IMX7 - ARM cortex M4.

The instructions in 'NXP's Getting_Started_with_FreeRTOS_BSP_for_i.MX_7Dual.pdf' are old and there isn't much for Linux.

Using Ubuntu 22.04LTS

1. I downloaded the compiler from https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads : x86_64 Linux hosted cross toolchains, AArch32 bare-metal target (arm-none-eabi):    gcc-arm-11.2-2022.02-x86_64-arm-none-eabi.tar.xz
2. I downloaded and installed Eclipse: eclipse-cpp-2022-03-R-linux-gtk-x86_64.tar.gz

When I compile a simple hello world program, I get the following error messages:

• Do I have the right compiler? Seems like this compiler uses cygwin which is meant for windows.
• Are there any instructions on how to setup the IDE under Linux?

Any pointers will be appreciated
