Hi Wiznet Team, I am using Wiznet's W55RP20-EVB-Pico board for developing my application using S2E in addition with some GPIO controlling as per my project requirements. I have cloned W55RP20-S2E source code from github link: git clone --recurse-submodules After cloning to my folder, i opened VS code steps followed as: 1. open Developer command prompt with admin rights 2. type CODE 3. VS code open 4. open folder where I have cloned source code 5. Configure compiler GCC 6. Build project Build process generates error: [build] from D:\URVI\Projects_Backup\Wiznet\W55RP20_S2E\W55RP20-S2E\port\app\http_server\src\httpServer.c:13: [build] D:\URVI\Projects_Backup\Wiznet\W55RP20_S2E\W55RP20-S2E\libraries\pico-sdk\src\common\pico_base_headers\include/pico/config.h:23:56: fatal error: D:/URVI/Projects_Backup/Wiznet/1/W55RP20-S2E/libraries/FreeRTOS-Kernel/portable/ThirdParty/GCC/RP2040/include/freertos_sdk_config.h: No such file or directory [build] 23 | #include __PICO_XSTRING(PICO_CONFIG_RTOS_ADAPTER_HEADER) [build] | ^ [build] compilation terminated. Why this downloaded code gives an error? Any solution for this? ## Replies ### Reply 1 by UrviShah, 2025-06-10 check recursive sub module update and status: D:\URVI\Projects_Backup\Wiznet\W55RP20_S2E\W55RP20-S2E>git submodule update --init --recursive Skipping submodule ''libraries/aws-iot-device-sdk-embedded-C/libraries/aws/device-defender-for-aws-iot-embedded-sdk/test/unit-test/Unity'' Skipping submodule ''libraries/aws-iot-device-sdk-embedded-C/libraries/aws/device-shadow-for-aws-iot-embedded-sdk/test/unit-test/CMock'' Skipping submodule ''libraries/aws-iot-device-sdk-embedded-C/libraries/aws/fleet-provisioning-for-aws-iot-embedded-sdk/test/unit-test/Unity'' Skipping submodule ''libraries/aws-iot-device-sdk-embedded-C/libraries/aws/jobs-for-aws-iot-embedded-sdk/test/unit-test/Unity'' Skipping submodule ''libraries/aws-iot-device-sdk-embedded-C/libraries/aws/ota-for-aws-iot-embedded-sdk/source/dependency/3rdparty/tinycbor'' Skipping submodule ''libraries/aws-iot-device-sdk-embedded-C/libraries/aws/ota-for-aws-iot-embedded-sdk/source/dependency/coreJSON'' Skipping submodule ''libraries/aws-iot-device-sdk-embedded-C/libraries/aws/ota-for-aws-iot-embedded-sdk/test/cbmc/FreeRTOS-Kernel'' Skipping submodule ''libraries/aws-iot-device-sdk-embedded-C/libraries/aws/ota-for-aws-iot-embedded-sdk/test/unit-test/CMock'' Skipping submodule ''libraries/aws-iot-device-sdk-embedded-C/libraries/aws/sigv4-for-aws-iot-embedded-sdk/test/unit-test/CMock'' Skipping submodule ''libraries/aws-iot-device-sdk-embedded-C/libraries/standard/backoffAlgorithm/test/unit-test/Unity'' Skipping submodule ''libraries/aws-iot-device-sdk-embedded-C/libraries/standard/coreHTTP/test/unit-test/CMock'' Skipping submodule ''libraries/aws-iot-device-sdk-embedded-C/libraries/standard/coreJSON/test/unit-test/Unity'' Skipping submodule ''libraries/aws-iot-device-sdk-embedded-C/libraries/standard/coreMQTT/test/unit-test/CMock'' D:\URVI\Projects_Backup\Wiznet\W55RP20_S2E\W55RP20-S2E>git submodule status dbf70559b27d39c1fdb68dfb9a32140b6a6777a0 libraries/FreeRTOS-Kernel (V11.1.0) 2d1dacd946b5d9612439559655ad9fd1b0895940 libraries/aws-iot-device-sdk-embedded-C (202211.00-26-g2d1dacd9) b981401e7f3d07015619adf44c13998e13e777f9 libraries/ioLibrary_Driver (W5500_PHY_LINK-93-gb981401) 2ca6c285a0dd3f33982dd57299012dacab1ff206 libraries/mbedtls (v3.6.0) efe2103f9b28458a1615ff096054479743ade236 libraries/pico-sdk (2.0.0) Second, check if the missing file exists in your project structure. Look for freertos_sdk_config.h in the FreeRTOS-Kernel directory: It is present in that location Third, try cleaning and rebuilding the project completely by deleting any existing build directories and rebuilding from scratch.: Done , but again same error I wonder does any one face this kind of problem? Why am I getting this error? ### Reply 2 by Hannah, 2025-06-12 (in reply to reply 1) We recommend the following versions for successful build and development: - **pico-sdk**: `2.0.0` - **ARM GCC Toolchain**: `13.2.Rel1` > Using other versions of the toolchain may result in build errors. If it still doesn’t work with the above settings, try compiling it using the Pico extension. If it still fails, delete the entire cloned source code and clone it again. ### Reply 3 by UrviShah, 2025-06-12 (in reply to reply 1) Hi **Hannah** , Thank you for the reply. As you suggested i deleted entire cloned directory and again tried with the steps suggested: 1. git clone --recurse-submodules 2. git submodule update --init --recursive 3. git submodule status 4. version for pico sdk is: **pico-sdk**: `2.0.0` 5. compiler used: **ARM GCC Toolchain**: `13.2.Rel1` check logs: dbf70559b27d39c1fdb68dfb9a32140b6a6777a0 libraries/FreeRTOS-Kernel (V11.1.0) 2d1dacd946b5d9612439559655ad9fd1b0895940 libraries/aws-iot-device-sdk-embedded-C (202211.00-26-g2d1dacd9) b981401e7f3d07015619adf44c13998e13e777f9 libraries/ioLibrary_Driver (W5500_PHY_LINK-93-gb981401) 2ca6c285a0dd3f33982dd57299012dacab1ff206 libraries/mbedtls (v3.6.0) efe2103f9b28458a1615ff096054479743ade236 libraries/pico-sdk (2.0.0) [cmake] -- The C compiler identification is GNU 13.2.1 [cmake] -- The CXX compiler identification is GNU 13.2.1 [cmake] -- Detecting C compiler ABI info [cmake] -- Detecting C compiler ABI info - done [cmake] -- Check for working C compiler: c:/Program Files (x86)/Arm GNU Toolchain arm-none-eabi/13.2 Rel1/bin/arm-none-eabi-gcc.exe - skipped I tried this not only in one PC/machine but in other PC also it is giving me same errors even when trying with same procedures and versions.

It has been modified to allow building with a newer GCC version, so we recommend trying a fresh build. Thank you. ### Reply 5 by Grace_Koo, 2025-06-19 And we recommend building using the Pico extension for Visual Studio Code. --- Source: https://maker.wiznet.io/forum/15754
