1 year ago Figure out that the problem was in my environment variables. I Solve my problem using *CMake instead of Make for me works with these steps:
- First I create a
toolchain-arm-none-eabi.cmaketoolchain file with the content:
set(CMAKE_SYSTEM_NAME Generic)
set(CMAKE_SYSTEM_PROCESSOR arm)
set(CMAKE_SYSTEM_VERSION 1)
# this info holds the location of installation
set(CMAKE_STAGING_PREFIX /tmp/mbedTLS)
set(CMAKE_C_COMPILER /usr/bin/arm-none-eabi-gcc)
set(CMAKE_CXX_COMPILER /usr/bin/arm-none-eabi-g++)
set(CMAKE_MAKE_PROGRAM=/usr/bin/make)
set(CMAKE_C_FLAGS="-mcpu=cortex-m0plus -mthumb -O2")
set(CMAKE_CXX_FLAGS="-mcpu=cortex-m0plus -mthumb -O2")
set(CMAKE_EXE_LINKER_FLAGS " --specs=nosys.specs")
set(CMAKE_STRIP /usr/bin/arm-none-eabi-strip)
set(CMAKE_FIND_ROOT_PATH /usr/arm-none-eabi)
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)- I put my
toolchain-arm-none-eabi.cmakefile in a folder and from that same folder I ran:
# Download the `.tar.gz` of MbedTLS
wget https://github.com/Mbed-TLS/mbedtls/archive/refs/tags/v3.2.1.tar.gz
# unzip
tar zxf v3.2.1.tar.gz
# Configure to crypto_baremetal
mbedtls-3.2.1/scripts/config.py -w mbedtls-3.2.1/include/mbedtls/mbedtls_config.h crypto_baremetal
# Folder to build
mkdir mbedtls
# Go inside build folder
pushd mbedtls
# Configuring (necessary force that compiler works to CMake)
cmake -DCMAKE_C_COMPILER_WORKS=1 \
-DCMAKE_BUILD_TYPE=Release -DUSE_SHARED_MBEDTLS_LIBRARY=OFF \
-DUSE_STATIC_MBEDTLS_LIBRARY=ON \
-DENABLE_PROGRAMS=OFF -DENABLE_TESTING=OFF \
-DCMAKE_EXPORT_COMPILE_COMMANDS=ON \
-DCMAKE_TOOLCHAIN_FILE=../toolchain-arm-none-eabi.cmake ../mbedtls-3.2.1
# Compiling and installing
make all install
# Free diretory stack
popdThen inside the folder /tmp/mbedTLS I have:
cd /tmp/mbedTLS

Summary
I’m trying to compile the mbedTLS library to use with RP2040 microcontroler (in a .a library file), to use in with CMake pico-sdk of Raspberry Pi Pico board, but I’m getting an linker error.
System information
Mbed TLS version (number or commit id): 1a100b69a4132 (branch development) Operating system and version: Pop!_OS 22.04 LTS x86_64 Configuration (if not default, please attach
mbedtls_config.h): crypto_baremetal Compiler and options (if you used a pre-built binary, please indicate how you obtained it): arm-none-eabi-gcc (15:10.3-2021.07-4) 10.3.1 20210621 Additional environment information: Compilling for RP2040 MCU, using compiler flags and env variables:Expected behavior
The compilation of MbedTLS library for baremetal_crypto configuration. (A
.alibrary file)Actual behavior
The error:
Steps to reproduce
In a linux-based environment (more specificaly in a Ubuntu based Environment):
Additional information
I followed the instructions of README.md did I miss something? Already try to compile in my Raspberry Pi Zero W (using the OS: Raspbian GNU/Linux 11 (bullseye) armv6l) and I get the same result (The same errors).
