For example, for the ARM Compiler 5: + +``` +mbed compile -m K64F -t ARM +``` + +Your PC may take a few minutes to compile your code. At the end you should get the following result: + +``` +[snip] ++----------------------------+-------+-------+------+ +| Module | .text | .data | .bss | ++----------------------------+-------+-------+------+ +| Misc | 13939 | 24 | 1372 | +| core/hal | 16993 | 96 | 296 | +| core/rtos | 7384 | 92 | 4204 | +| features/FEATURE_IPV4 | 80 | 0 | 176 | +| frameworks/greentea-client | 1830 | 60 | 44 | +| frameworks/utest | 2392 | 512 | 292 | +| Subtotals | 42618 | 784 | 6384 | ++----------------------------+-------+-------+------+ +Allocated Heap: unknown +Allocated Stack: unknown +Total Static RAM memory (data + bss): 7168 bytes +Total RAM memory (data + bss + heap + stack): 7168 bytes +Total Flash memory (text + data + misc): 43402 bytes +Image: .\.build\K64F\ARM\mbed-os-example-blinky.bin +``` + +### Program your board + +1.

Start uVision. +1. Import the uVision project generated earlier. +1. Compile your application and generate an `.axf` file. +1. Make sure uVision is configured to debug over CMSIS-DAP (From the Project menu > Options for Target '...' > Debug tab > Use CMSIS-DAP Debugger). +1. Set breakpoints and start a debug session. + + + +## Troubleshooting + +1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9` + + ``` + mbed --version + ``` + + If not, you can update it easily: + + ``` + pip install mbed-cli --upgrade + ``` + +2. If using Keil MDK, make sure you have a license installed. [MDK-Lite](http://www.keil.com/arm/mdk.asp) has a 32KB restriction on code size.
