Hello Samuli,

I think I have found the file defining the sectors info for the bootloader. You can modify it as follows:

  • Open the mbed-os/tools/arm_pack_manager/index.json file
  • Search for STM32F411RETx. You should find something like:
        "name": "STM32F411RETx", 
        "processor": {
            "Symmetric": {
                "core": "CortexM4", 
                "fpu": "SinglePrecision", 
                "mpu": "Present", 
                "units": 1
            }
        }, 
        "sectors": [
            [
                134217728, 
                16384
            ], 
            [
                134283264, 
                65536
            ], 
            [
                134348800, 
                131072
            ], 
            [
                536836096, 
                528
            ], 
            [
                536854528, 
                4
            ]
        ],
  • Select the “sectors” section for copying and then search for STM32F401RETx. You should find something like:
"name": "STM32F401RETx", 
        "processor": {
            "Symmetric": {
                "core": "CortexM4", 
                "fpu": "SinglePrecision", 
                "mpu": "Present", 
                "units": 1
            }
        }, 
        "sectors": null,
  • Paste the “sectors” section from the STM32F411RETx here so it becomes:
"name": "STM32F401RETx", 
        "processor": {
            "Symmetric": {
                "core": "CortexM4", 
                "fpu": "SinglePrecision", 
                "mpu": "Present", 
                "units": 1
            }
        }, 
        "sectors": [
            [
                134217728, 
                16384
            ], 
            [
                134283264, 
                65536
            ], 
            [
                134348800, 
                131072
            ], 
            [
                536836096, 
                528
            ], 
            [
                536854528, 
                4
            ]
        ],
  • Save the file and compile the bootloader for the NUCLEO_F401RE target.
