I am using MX Linux OS and trying to work with the STM32F103C8T6 MCU. Following the user manual Beginning STM32 by Warren Gay, I successfully installed the Git clone of stm32f103c8t6, libopencm3, and FreeRTOS as per the manual.
When I downloaded and unzipped the ARM cross-compiler, the files were saved under the /opt/gcc-arm folder.
Upon typing arm-none-eabi-gcc --version, I encountered a “command not found” error.
Upon further investigation, I typed:
$ ls -l /opt/gcc-arm/bin
It listed arm-none-eabi-gcc in the following format (in green):
-rwxr-xr-x 2 1001 1001 1296976 Nov 24 2020 arm-none-eabi-gcc
Similarly, the type gcc command gives the output:
gcc is /usr/bin/gcc
Instead of:
arm-none-eabi-gcc is hashed (/opt/gcc-arm/bin/gcc)
as mentioned in the user manual.
The type arm-none-eabi-gcc command outputs:
not found
As I understand, the green color of the file means it is executable, but I am unable to determine why the computer is not recognizing the command.
Finally, when running the make command, I received the following response:
user@mx:~/stm32f103c8t6
$ make
