Hi Ralph, Very glad to hear from you. Thanks. Following your steps proposed, according to my experience, can not get the source code of Mbed RTOS in the project, yet. I want to kown how to create project with source codes of Mbed sytem including RTOS based on Keil IDE. Thanks in advance!

Best regards, Qingfeng, Yuan

Hi Qingfeng,

Perhaps something has gone wrong with your export or import. We've updated our answer to include two screen captures. On the export you will get a zip file that you need to unzip. That will have all the Mbed OS files along with a uv5 project file. Open the project file in uVision (you may get prompted to add a device pack) and then you'll readily see all the Mbed files in the mbed-os folder. Please check the screen captures above. -Ralph, Team Mbed

Hi Ralph, First of all, thanks for your efforts. As to screen captures updated from you, I still can not find source code of RTOS. No matter what, I will follow your steps provided to further confirm. Any question will follow this topic ,and need your helps again, thanks.

Hi Ralph, Following the steps provided from you, I can get the project based on KEIL IDE. The files list under the folder of 'mbed-os' doesn't contain the files related to RTOS kernel, which is same as screen captures you posted before. I need the full source code, especillay related to RTOS kernel. Do you have any solution to this question? Thanks in advance!

Best regards, Vine

Hi Vine,

If you aren't seeing the proper directory structure we suspect you didn't start with a proper Mbed project or the export didn't work. Is your exported project building in uVision? What project are you exporting and what target have you selected?

We double-checked that the "Import into MBED IDE" link from this page will work:

• https://os.mbed.com/docs/v5.6/tutorials/blinky-on-the-arm-mbed-online-compiler.html

Once the project is in the Online Compiler you right-click on the project and select "Export Program". The zip file you get from the export will be over 20MB in size. The Mbed directory structure consists of several sub-folders with kernel files located in the "mbed-os\rtos" folder.

Hi Ralph, Maybe, there is a misunderstanding between us. I mean I can get the project with some files, which is same as screen captures you posted before. But I cannot find the files RTOS kernel located in the "mbed-os\rtos" folder. Are you sure that you can get the full souce code following your steps? It includes RTOS kernel files, such as Rtx_thread.c, Mbed_boot.c and so. Thanks again! Looking forward to your suggestion! Best regards, Vine

Hi Vine,

We would like to get to the root cause of your issue but you are not providing any beneficial/concrete information about the problem! Please answer the questions that we have asked you in our previous comment.

In our exported project we are finding rtx_thread.c and mbed_boot.c right where they should be - under mbed-os\rtos\TARGET-CORTEX\rtx5\RTX\Source and mbed-os\rtos\TARGET-CORTEX respectively.

Hi Ralph, Following steps you provided absolutely, including the same hardware selection: lpc1768. Exported project based on KEIL includes the RTOS kernel files, as you descripted before. But exporting project based on another hardware selection: nucleo_f030r8, that's different. No kernel source code of RTOS is included in project. That's werid. Do you have suggestion??

Hi Vine,

The Nucleo F030R8 doesn't support Mbed OS5 - likely because the available Flash/RAM is too small. So you are getting an Mbed OS2 project that is packaged differently. You will probably have to use the CLI (command line interface). The Markdown documentation for CLI is here:

• https://github.com/ARMmbed/mbed-cli

To get the full Mbed OS2 source code you can import an OS2 project like this one:

• mbed import https://os.mbed.com/users/mbed_official/code/mbed_blinky/

Then you can export it to uVision with:

• mbed export -i uvision5 -m nucleo_f030r8

I've moved on to Python3 so can't test this myself as OS2 only supports Python2.
