I can compile and flash the code to microcontroller using mbed-cli, but the output isn't working

I installed and configured mbed-cli for Linux, following the official documentation. I can compile and flash the code to micro controller but the output isn't working (not even serial print), but it is working if I compile and flash using mac-OS in a macbook).

I tried updating the version and reinstalling too. All my configurations match the screenshots of the documentation.

Compilation output:

WARNING: MBED_ARM_PATH set as environment variable but doesn't exist
Building project xxxx_v1 (LPC1768, GCC_ARM)
.

.
  Filling region application with ./BUILD/LPC1768/GCC_ARM/xxxx_v1_application.bin
.

.
Image: ./BUILD/LPC1768/GCC_ARM/xxxx_v1.bin

Config list output:

[mbed] Global config:
GCC_ARM_PATH=/usr/bin
ARM_PATH=home/xxxxteam/ARM_Compiler_5.06u6

[mbed] Local config (/home/xxxxteam/Documents/MBED/xxxx_v1):
TOOLCHAIN=GCC_ARM
TARGET=LPC1768

Code to flash into SD card:

#mbed compile -m LPC1768 -t GCC_ARM
cd BUILD/LPC1768/GCC_ARM/
rm firmware.bin
mv xxxx_v1_application.bin firmware.bin
rm $1/*.bin
cp firmware.bin  $1 
umount $1

first argument in above code is 'media/xxxxteam/xxxxcycle'

Even a simple code of printing hello world is not working.

Source is the same, but compiler is different? I couple of possibilities: maybe crt (C runtime, startup code) differs; maybe one of the compilers initialises something, the other doesn't; maybe built-in libraries differ; maybe your code has some #ifdef for specific compilers. I would go for the simplest possible working piece of code (just a blinky?), and compare compiled binaries with disassembler - hopefully something stands out. – domen – 2019-04-10T08:25:20.857

Will do that and test, Thanks. – ElecTron – 2019-04-10T09:59:41.503
