Hi,

After long time again started working on nordic controller's.
Previously my pc was properly configured for NRF5x environment which includes gcc and flahser.

Recently i got nrf52832 board and i started working on..

now, I set up the path for arm-none-eabi-gcc toolchain. and export the path arm-none-eabi-gcc toolchain..
But while compiling i got following error's.

~/projects/nrf5x/sdk/nRF5_SDK_15.2.0_9412b96/examples/peripheral/blinky/pca10040/blank/armgcc
/home/stech/compiler/gcc/gcc-arm-none-eabi-6-2017-q2-update/bin/arm-none-eabi-gcc: 1: /home/stech/compiler/gcc/gcc-arm-none-eabi-6-2017-q2-update/bin/arm-none-eabi-gcc: ELF: not found

Please set values in: "/home/stech/projects/nrf5x/sdk/nRF5_SDK_15.2.0_9412b96/components/toolchain/gcc/Makefile.posix"
according to the actual configuration of your system.
../../../../../../components/toolchain/gcc/Makefile.common:129: *** Cannot continue.  Stop.

And changed the file nRF5_SDK_15.2.0_9412b96/components/toolchain/gcc/Makefile.posix.

following is the updated file.

GNU_INSTALL_ROOT ?= /home/stech/compiler/gcc/gcc-arm-none-eabi-6-2017-q2-update/bin/
GNU_VERSION ?= 6.3.1
GNU_PREFIX ?= arm-none-eabi

i am using ubuntu 16.04 32-bit..

here are the arm-gcc version i tried.

gcc-arm-none-eabi-4_8-2014q3-20140805-linux.tar.bz2

gcc-arm-none-eabi-6-2017-q2-update-linux.tar.bz2

gcc-arm-none-eabi-7-2018-q2-update-linux.tar.bz2

what could be the problem?

 

you have to check existance of "arm-none-eabi-gcc" file in "/home/stech/compiler/gcc/gcc-arm-none-eabi-6-2017-q2-update/bin/" location.
if there's no file,you may need to compile the sources of gcc-arm package you have downloaded.or install them automatically using package managers like synaptic,apt-get,etc and set a new location.

 

It says cannot find a file, does that file exist or do you need a different path for that file? I'm not at my computer now, but there is a config file that you need to edit to change the path, i don't remember the file name but can check later. The keil uvision compiler is really nice and free for binaries under 32k, better than eclipse/gcc. But for larger binaries gcc will get the job done.

 

The config file I was thinking of is in the SDK directory under components/toolchain/gcc/Makefile.windows (assuming you're on Windows).

If you want to get setup for Eclipse (much better than command line gcc as you will have a visual debugger), then this article will get you going:

It's from 2015 so probably a little outdated, but I was able to get things working using that as a reference.
