Mbed Sdcard Error

Development Platforms

As you may know, recently we’ve refactored mbed build script and now it uses native mbed tools in order to enable mbed-specific workflow (support for mbed_app.json config files, original build logic, etc) and several options like PIO_FRAMEWORK_MBED_FILESYSTEM_PRESENT became unnecessary (like it or not, but mbed tools build the entire framework). Since the mbed framework exists in two forms - mbed 2.0 and mbed OS 5 we decided to keep -DPIO_FRAMEWORK_MBED_RTOS_PRESENT option to allow the user to switch between these forms. I’m not entirely sure, but filesystem feature depends on OS functionality and without OS you’ll just get a bunch of compilation errors. But I think it might be possible to add this feature to the project as a standalone library. In any case, please let me know if you are able to compile your code without OS in the online mbed compiler.

And as I mentioned above, the configuration of the project should be done in the mbed_app.json file, something like this:

{
    "target_overrides": {
        "*": {
            "target.features_add": ["STORAGE"],
            "target.components_add": ["SD"],
            "platform.stdio-baud-rate": 115200,
            "target.stdio_uart_tx": "PA_9",
            "target.stdio_uart_rx": "PA_10"
        }
    }
}
