Reorder the 'SYS' menus so that they follow 'features / hardware / display' which should be less confusing for users.
Also fix a bug with a non-implemented menu entry in the 'SYS1' menu on OSTC 4 (mikeller)

| 489 | 1 # How to Create From Scratch a Project for _CPU1-Discovery_ Code # |
| 2 | |
| 3 The OpenSTM32 wiki have a [page](http://www.openstm32.org/Getting%2Bstarted%2Bwith%2BSystem%2BWorkbench%2Bfor%2BSTM32) to start a project from scratch. With the latest version of every support libraries and sources from ST. But here I prefer to have a project with the support files validated (and compatible) with the _OSTC4_ code. | |
| 4 | |
| 5 ## Start with an Empty Project ## | |
| 6 | |
| 7 **Special Notes**: | |
| 8 | |
| 9 - _Linux_ users should read about this **well known _Eclipse_ bug** : http://www.openstm32.org/faq1#q22 | |
| 10 - We do have a _STM32F427IIT6_ chip as CPU1. But the support file provided by _ST_ lake for _LCD TFT Display Controller_ (aka LTDC), even in the latest available version 1.7.2 from 2017-11-06... So we use the STM32F429IITx support file instead, that seems to be similar enough. | |
| 11 | |
| 12 In the following description, I suppose you used _mercurial_ to clone the sources into a **D:\Dev\OSTC4** directory. Make the changes for your own settings... | |
| 13 | |
| 14 0. Start the IDE. On most machine it will be the `eclipse` in the _Ac6_ folder you installed. | |
| 15 1. Create an empty project: `File` > `New` > `C Project` | |
| 16 2. Choose `AC6 STM32 MCU Project` and `AC6 STM32 MCU GCC`. Click `Next` | |
| 17 Note: **make sure NOT TO CLICK FINISH... as it will skip all the rest of the configuration wizard !** | |
| 18 3. Keep `Debug` and `Release` configurations. Click `Next` | |
| 19 4. Create a new board, that you can name **OSTC4-CPU1-F429**, by choosing: | |
| 20 > Series: `STM32F4` | |
| 21 > Mcu: `STM32F429IITx` | |
| 22 > Debug: `JTAG` | |
| 23 Click `Next`. | |
| 24 5. Keep `No firmware` and select `Don't generate startup files`. Then click `Finish` | |
| 25 | |
| 26 ## Configure Various Settings ## | |
| 27 | |
| 28 1. In the _C/C++ Projects_ explorer, select your project top-level folder | |
| 29 2. Right on it, select `Properties`, `Resource` and set `Text file encoding` to **UTF-8** | |
| 30 3. Right on it, select `Properties`, `Resource` then `Linked Resources` and click on `New...` to define a new variable **OSTC4** that points to your source folder **D:\Dev\OSTC4** (or whatever path you used on your system). | |
| 31 This should allow to change the project's origin with a single variable change. | |
| 32 | |
| 33 # Add Sources Folders # | |
| 34 | |
| 35 1. In the _C/C++ Projects_ explorer, select your project top-level folder | |
| 36 2. Right-click to add a `New` > `Folder`. In `Advanced settings >` click `Link to alternate location` and then the `Variables...` button. Click on the **OSTC4** variable, then click `Extend...` and select the **Common\\** sub-directory. Click `Finish` | |
| 37 3. Do the same to import the linked folder **OSTC4\Discovery** | |
| 38 | |
| 39 ## Make _Eclipse_ aware you just added sources, not junk ## | |
| 40 | |
| 41 (_Note: this step is only useful on specific versions of Eclipse. And already done by default on others..._) | |
| 42 | |
| 43 1. In the _C/C++ Projects_ explorer, open your project top-level project. | |
| 44 2. Right click on the `Common` folder, select `Resource Configurations...`, and `Exclude from build`. Make sure to UNCHECK both `Debug` and `Release` check-boxes. | |
| 45 3. Do the same for the `Discovery` folder. | |
| 46 | |
| 47 ## Make _Eclipse_ aware not to compile templates ## | |
| 48 | |
| 49 Some sources or directories in the _ST_ distribution contains source you shall not compile. So you should tell _OSE_. | |
| 50 | |
| 51 1. In the _Project Explorer_, open item `Common/Drivers/STM32F4xx_HAL_DRIVER_v120/Src`. Right click on `stm32f4xx_hal_msp_template.c`source file, select `Resource Configurations...`, and `Exclude from build`. Make sure both `Debug` and `Release` check-boxes are CHECKED. | |
| 52 2. Do the same on the `Common/Drivers/STM32F4xx_v220/Source/Templates` directory. | |
| 53 | |
| 54 # Compile # | |
| 55 | |
| 56 1. Select your top-level project, right-click to edit `properties`. In `C/C++ Build` choose `Settings`, then `MCU GCC Compiler` and `Optimization`. Choose `Optimization Level`: -Os (To reduce flash time) | |
| 57 | |
| 58 Ok, sources are there. You can read them. But you need a few more efforts to let the IDE find everything he requires to compile _CPU1 Discovery_ firmware. | |
| 59 | |
| 60 ## Add include paths ## | |

62 1. Select your top-level project, right-click to edit `properties`. In `C/C++ Build` choose `Settings`, then `MCU GCC Compiler` and `Includes`. **Make sure to select `Configuration: [All Configurations]` **. Click `Add...` choose `Workspace...` and select the `Common/Drivers/CMIS/Include` directory. |

63 2. Do the same for `Common/Drivers/STM32F4xx/Include` directory. |

64 3. Do the same for `Common/Drivers/STM32F4xx_HAL_DRIVER/Inc` directory. |
| 489 | 65 4. Do the same for `Common/Inc` directory. |
| 66 5. Do the same for `Discovery/Inc` directory. | |
| 67 6. Use the _Move Up_ icon to make sure `Discovery/Inc` is first. | |
| 68 7. Use the `Configuration:` pop-up to check you have all the includes in both `Debug` and `Release` configuration. | |
| 69 | |
| 70 Once done, If you go to the _C/C++ Projects explorer_, open your top-level project, and open the `Includes` item, you should see: | |
| 71 | |
| 72 - a few lines added by the system `.../Ac6/Workbench/plugins/.../compiler/...` with include paths required by the GCC compiler. | |
| 73 - then your 5 include directories (shown in alphabetic order, not priority order... too bad). Make sure to open each of them and to double-click on a .h file to check it opens correctly in the IDE. | |
| 74 | |
| 75 ## Add Link Options ## | |
| 76 | |
| 77 1. Select your top-level project, right-click to edit `properties`. In `C/C++ Build` choose `Settings`, then `MCU G++ Linker` and `General`. | |
| 78 And select _linker Script_: `OSTC4/Common/CPU1-F429.ld` | |
| 79 2. In `C/C++ Build` choose `Settings`, then `MCU GCC Linker` and `Miscellaneous`. Add option -u _printf_float in Linker flags. This is necessary to prevent IDE warning "The float formatting support (-u _printf_float) is not enabled from linker flags". | |
| 80 | |
| 81 ## Prepare generation of bin file ## | |
| 82 1. Select your top-level project, right-click to edit `properties`. In `C/C++ Build` choose `Settings`, then tab `Build Steps` and `Post build step command`. | |

83 2. Add option -R .upper\* and -R.font_firmware_data to the command to removed the upper memory section, which is provided by the font library =>arm-none-eabi-objcopy -R .upper\* -R.font_firmware_data -O binary "${BuildArtifactFileBaseName}.elf" "${BuildArtifactFileBaseName}.bin"; arm-none-eabi-size "${BuildArtifactFileName}" |

| 85 ## Build ELF firmware ## | |
| 86 | |
| 87 1. Click the `Build` button (hammer icon) on the top bar. |
